Identification and Marking of Materials & Equipment
The requirements of Appendix-B shall be strictly applied to ensure easy identification of material on arrival at site.
Preservation Requirements
Material or equipment from vendors often must be stored before it is put in use. Consideration should also be given to atmospheric conditions and the length of storage time. The preservation of new materials is directly controlled by the following factors:
-
Effective delivery scheduling of new equipment can reduce or eliminate the need for storage protection. When equipment is stored over long periods, regular inspections must be scheduled to assure protection has not deteriorated.
-
Some protective measures may be provided by the vendor before shipment. It may be advisable to specify the protection required in the purchase order. Cost and available facilities usually determine where protection should be applied. If protection must be removed for receiving inspection, final protection must be provided at the plant site.
-
Acceptable oil-resistant, water-resistant and pressure sensitive tapes these tapes have less than 250
ppm chloride content (not applicable to stainless steels)
In consideration of the fact that the material protection is subject to many variables, site/ stores individual circumstances must be considered and additional measures shall be taken where necessary. It is therefore recommended to check the integrity of the protection after the arrival of the equipment/materials on site and whether any changes have occurred in the duration, location or conditions for storage
- The desiccant bags shall be kept inside the aluminum foil or outside plastic wrap to control the humidity
and are provided with humidity indicators in steps of 30%, 40% & 50%.
- The monitoring frequency shall be submitted along with the preservation procedure based on manufacturer recommendations. The equipment shall be physically inspected for rust marks or any other deterioration which is suitably attended to, before applying preservatives.

Methods of Preservation
Equipment and Materials shall be protected as described herein, these items include but are not limited to the following:
Exterior Protection
A. Cocooning:
Cocooning is the envelopment of equipment in a single plastic coating. The coating is applied by spraying either directly onto the equipment body or onto a special wrapping of paper or wire netting. Before cocooning, the equipment shall be carefully cleaned of grease and dust, and then dried. Cocooning should conform to the equipment Manufacturer’s recommendations. Where possible, the envelope should be pressurized by inert gas (small overpressure).
B. Painting:
Routine maintenance painting programs for external protection should be continued.
C. Coating:
VCI for temporary protectives suitable for the bright-finished moving parts of mechanical equipment. Storage under cover is preferred. Before application, surfaces shall be thoroughly cleaned and dried.
D. Wrapping:
Wrapping with waterproof paper or VCI paper. However, the equipment protected in this way should be
stored under cover.
Interior Protection
A. Oil Mist/ coating:
Internal oil coating of stationary equipment may be carried out by spraying or, if the foundation is strong enough, by filling and subsequent draining. Use can be made of VCI Class III or of a light oil of medium viscosity (approximately 35 mPa.s at 38°C) to form a protective film on the surface.
B. Filling:
Often one of the factors limiting the filling of process and storage equipment is the strength of the foundation. Adequate measures shall be taken to allow for expansion of the filling fluid, which can be a gas oil or inhibited fresh water (or inert gas, see below).

C. VPCI/ VPI/ VCI/VSI:
Can be used advantageously for the internal protection of engines, bearings, turbines, heat exchangers, pipes, drums, small tanks and like equipment. Care should be taken to ensure that no pockets of water are present and that the piece of equipment to be protected is dry and properly closed off from the atmosphere. Refer to Appendix A2 for details of each type.
D. Dry inert gas filling:
All hermetically closed equipment may be protected by drying the air or displacing it by an inert gas, e.g. nitrogen, and maintaining a slight positive internal pressure. This pressure is not necessary if a desiccant is present or a vapour phase inhibitor is used.
E. Desiccants:
Drying agents, such as silica gel, can be used inside closed equipment. The desiccant should be placed in a suitable container and periodically renewed. It shall not be used in combination with VCI.
F. Electric heating:
The following methods of electric heating may be considered:
a. Fan heaters; for space heating, e.g. sub-stations, control rooms, basements. b. Warm air (strip heating, electric trace heating or lamp bulbs); for equipment which is
cocooned or otherwise enclosed.
c. Anti-condensation heaters for electrical equipment
External and Internal Metal Surfaces Preservation
In case it is impractical to seal off equipment from the atmosphere by wrapping or boxing, the unpainted surfaces, if any, shall be protected as follows:
a) External non-painted surfaces, except air cooler finned tubing, including bolting and flange faces, shall be thoroughly cleaned and given a coating of a P-1 preservative (Refer to Appendix - A1)
b) Exposed shafts and shaft couplings shall be coated with a P-1 preservative and wrapped with waterproof moldable cloth, then sealed entirely with waterproof, cloth-backed duct tape. The shafts shall be free to rotate.
c) Oil lubricated pump bearing housings, equipment cases, stuffing boxes and gearboxes shall be fogged and filled 10 to 50 percent of the internal volume with VSI circulating oil. Subsequently, all openings shall be tightly sealed.

7 EXTERNAL AND INTERNAL PACKING
External Packing
Construction of Packing Containers
The container and interior packaging shall be designed so as to both absorb the shocks and relieve the destructive forces by means of cushioning material, or to distribute, localize and transform these forces in such a manner that the commodity and container will be able to withstand them without damage to the merchandise.
Selection of packing depends on the nature of the commodity. Items which completely fill the container and contribute to the strength of the package are normally the easiest and most economical to package. Articles which do not completely fill the selected container must be cushioned, braced, fastened, or blocked to prevent damage to the article itself or destruction of the container.
Minor disassembly and nesting to conserve shipping volume and prevent damage shall be followed. Material requiring special jigs, fixtures, tooling or recalibration for reassembly shall not be dismantled. Parts, attachments, or fixtures of the commodity packed shall be boxed, or blocked and braced within the shipping container (where practical) containing the main unit, maintaining a low centre of gravity.
If the load must be kept upright, equip the packing with lift handles, skids, top peaks or gables, or some similar device to assure stowage and handling in an upright position. Break bulk items shall be equipped with lifting lugs when required.
Do not exceed whatever capacity the (box, crate, etc.) was designed to accommodate. Inner blocking and bracing must distribute the contents’ weight over interior surfaces rather than concentrate it on one or two critical points.
Bundles and Pallets
Unitize, palletize, or assemble cargo in the largest practical unit consistent with handling, weight and dimension limitations at transhipment points and destination. Material packed on pallets shall be enclosed and strapped to four way entry pallets. Material must fit pallet without large voids and must be capable of withstanding stacking without damage.
Material packed in bundles shall be segregated to length and size, shall be securely strapped (32 mm width heavy duty strapping) with a stretching tool, secured with crimped steel seals (spaced 900 mm apart) and skidded to permit stacking without damage. Bundles are not to exceed 1000 kg gross weight unless previously approved by the CONTRACTOR.
Sturdy commodities such as rough castings, structural or fabricated steel, heavy wall pipe, or tanks not subject to water or handling damage, shall be bundled, skidded, or secured to pallets for shipments.

thick.
c) Use 16 mm (5/8) inch diameter carriage bolts when fastening pieces over 92 mm thick.
Prevent loosening of nuts by using lock washers, or lock nuts, or deforming the bolt threads, or by staking the nut to the bolt.
Crates
Open crates can be used where contents are virtually indestructible and packing is required only to facilitate handling and stowage. Crates also serve well as over packs to consolidate fibreboard boxes or to provide unit pack stiffness to resist crushing. Three ways corner construction reinforced with diagonals shall be used for all crates that are not plywood sheathed.
Large crates usually must bear great superimposed loads. Ensure top strength by frequent (not more than 950 mm apart) top joists. When sheathed, place joists under sheathing.
Provide joist supports directly under joist ends. Reinforce floor at load bearing points when between skids or sill members.
To permit entry of forklifts, terminate end sheathing at flooring. Terminate side sheathing 12 mm short of skid bottom. To transfer load to the tines of the forklift, add additional cross members at 500 mm and 1000 mm from each end.
Ventilation holes shall be placed at intervals around the sides and ends of sheathed crates.
Provide drainage holes through the deck or space floor boards 10 mm apart when the crate structure above the base is not weatherproof or where condensation can occur.
Where excessive heat and humidity can be expected, additional ventilation should be provided. This can be done by drilling holes through the ends near the top, but not through any frame members. These holes should not be greater than 38 mm diameter nor more than three holes per 600 mm of crate length or width.

APPENDIX A2 RUST PREVENTIVE MATERIALS
A2.1 Vapor CORROSION Inhibitor (VCI)
VCI is a powder used to protect equipment that will be packaged or otherwise enclosed. VCI will assure constant protection for as long as two (2) years.
VCI reaches the metal surfaces in the vapor phase, and is absorbed on the metal to form an invisible film which prevents corrosion. Excellent protection is given to ferrous metals, most nonferrous metals and nonmetallic materials.
VCI can be applied dry by use of a Floc Gun or other dusting device. VCI powder shall be dispersed over exposed metal surfaces.
Application requirements and limitations shall be in accordance with manufacturer’s instructions.
Note: Vapor Corrosion Inhibitors or Volatile Corrosion Inhibitors (VCI) is generic terms for corrosion preventive products that contain environmentally safe chemicals.
A2.1.1 Safety Precautions
VCI shall be handled in accordance with the manufacturer’s instructions. VCI under normal conditions is not hazardous. However, workers exposed to air containing VCI powder shall wear dust masks.
A2.2 Vapor Corrosion Inhibiting Papers
VCI Vapor Barrier is a Kraft paper that is coated with a rust inhibiting chemical. It offers excellent protection for up to two (2) years when applied correctly. It is supplied in rolls, sheets and strips.
VCI papers give off invisible vapor that prevents oxygen in moisture from combining with steel to form rust. There are no special requirements for storing materials protected with these papers other than storing them in a cool, or shaded area and in a dry location. Packages could be opened briefly for inspection without loss of protection by merely resealing the package immediately following inspection.
A2.3 VCI Emitters
VCI Emitters are sponges that have been treated with Vapor Corrosion Inhibitor. Generally they have an adhesive backing for attachment to the inner surface of the enclosure where corrosion control is required. These emitters are convenient and an acceptable alternative to porous pouches of VCI.
A2.4 Vapor Space Inhibited (VSI)
VSI is an oily concentrate and contains an oil soluble, volatile anti-rust compound. This corrosion inhibitor fills the vapor space above the oil level to form a rust preventive barrier on exposed interior metal surfaces and combats vapor space rusting. VSI oil is available in one viscosity grade and is suitable for hydraulic, turbine, and general lubricating applications.

APPENDIX – C PREPARATION OF PRESSURE VESSELS AND HEAT EXCHANGERS FOR SHIPMENT
-
This section covers the requirements for MANUFACTURER’S preparation of shop fabricated pressure vessels and heat exchangers for shipment. These requirements do not apply to pressure vessels which are shipped in sections for assembly at the jobsite.
-
The MANUFACTURER/VENDOR shall submit for approval the complete details of the preparation for
shipment.
-
Vertical vessels shall be furnished with shipping saddles and tie downs. Vessel shells shall be designed to maintain structural integrity during shipment and storage when supported on horizontal supports. The dimensional tolerances of the ASME Code requirements and Project Specifications shall apply to the vessel after removal from the horizontal supports.
-
Horizontal vessels shall be shipped on their own supports.
-
Parts shipped or stored loose from the vessel are to be shop fit up by the MANUFACTURER/VENDOR
for field fit up prior to shipment of storage.
- Watertight Integrity
a) Carbon steel or low alloy steel vessels and heat exchangers without internal austenitic stainless steel
Lining.
All openings shall be made watertight against an external pressure of 1.05 kg/cm2. For covers on nozzles over 24 inch nominal diameter, adding external stiffening bars is an acceptable method to reinforce the cover plate.
All flanged connections which are not furnished with permanent blinds shall be covered with gasket and 12 mm minimum thick, full diameter, steel plate covers. The covers shall be installed with full bolting. Flanges drilled for bolting larger than ¾-inch diameter should be secured with ¾-inch diameter bolts and suitable cut washers. Flange edges shall be sealed with waterproof, cloth-backed tape.
