7.2.1 During the transportation of steel and cast iron pipe must meet the following conditions:

— when using cranes for loading and unloading long lengths of pipe to use spreader bars with slings, traverses vacuum or mechanical traverse in accordance with the approved schemes of slinging;

— apply the pipe-laying in piles of wood, polymer (retinochoroiditis) or other strips to enable grip during unloading in the case of laying tubes without lifting clamps;

— when transporting the pipe on the platforms to install side vertical wooden or polymer (rubber composite) stand connected on top of the pipes with a wire;

— do not place pads under the joints, tapered or upset ends of pipes;

— when transporting the pipe by rail to put them on the pad, eliminating the contact of the pipes with the metal elements of the bottom of the vehicle.

7.2.2 Loading or unloading pipes with thread should only be carried out with the set screw of the safety details.

When unloading pipes with thread manually, you need to use a rope loop and roll the pipe on a guide rail parallel to the stack, preventing damage to the threads and thread safety details.

7.3 Transportation fittings

Conditions of transportation of fittings in terms of the impact of mechanical factors should correspond to GOST 23170.

8 Storage

8.1 General provisions

8.1.1 During storage must be ensured the safety of products quality and quantity, as well as rational distribution of goods, excluding their entanglement and loss of identity.

8.1.2 in the storage and warehousing of consumer products should be divided into batches, sizes, grades of steel or cast iron, classes (groups), types of threaded connections, etc.

8.1.3 Products can be stored in a dry enclosed spaces, sheds or open storage areas.

8.1.4 Order of stacking of goods at storage locations and storage conditions depend on the type of products, dimensions of products, the type and method of packaging, the presence of preservation coatings.

8.1.5 it is Recommended that each storage location to supply a sign with the details placed on this place products.

8.1.6 Before styling products on storage check the conformity marking, the presence of safety parts or protective devices, as preservative coatings, permanent exterior protective coating and screw lubrication.

8.1.7 If the products conservation cover or screw lubrication the deadline for their conservation and protection should be 6 months, if the instrument of acceptance inspection of the goods unless stated otherwise.

Upon expiration of the term conservation protection coating or thread lubricant must be completely removed, and the product is made fresh.

8.1.8 Storage products with outer permanent protective coating must be conducted in conditions that prevent mechanical damage to the coating.

When storing goods with outer permanent protective coating over one month, is recommended to protect them from exposure to ultraviolet radiation, using sheds, or other means.

8.1.9 In case of loss installed on the ends of the jewelry safety parts or protective devices, they must be restored.

8.1.10 When storing products with a thread monitor the presence and condition of thread lubricant under the screw of the safety parts to prevent corrosion damage thread.

8.1.11 storage of the products in terms of the impact of climatic factors should take into account the GOST 15150.

8.2 Storage of steel and cast iron pipes

8.2.1 Pipe specified in 6.2.6 shall be stored in dry closed rooms. Allowed storage of such pipes under a canopy while protecting them from the falling precipitation.

8.2.2 Pipe should be stored by stacking in piles or on racks. Not allowed to lay the pipe, packages, and riots pipes to steel or concrete floor without the pads, as well as on the ground and the train tracks.

8.2.3 working (reference) surface of the rack must be positioned above the ground or floor must be level to prevent accidental rolling of the pipes.

The design of the rack should eliminate the deflection of the pipe or damage to their thread.

8.2.4 Between the rows of packs of pipe should be stacked at least three wooden, plastic or composite strips with a minimum thickness of 35 mm, uniformly distributed along the length of the packages.

For pipes of length less than 6 m is possible to have fewer spacers.

Allowed not to use spacers when stacking packages of tubes, is provided with securing means.

When stacking packages of pipe with couplings to the stacks several rows of them are placed so that the weight of the upper rows of tubes is distributed to the clutches of the lower ranks.

8.2.5 When storing the pipes, not bound in packages, the second and subsequent rows of pipes should be stacked on wooden, polymer, composite gaskets or lodgements.

When laying pipe with the belled end sockets in each row to be alternately directed in different directions.

8.2.6 When rolling pipe on the racks it is necessary to eliminate displacement of pipes at an angle to the axis of the rack, which can lead to collision and damage to pipe ends or threaded safety details.

8.2.7 In case of manual strapping of pipes load handling devices lifting means the height of stacks of pipes, tied in packages, and pipes with outside diameters of over 500 mm shall not exceed 5 m for tubing external diameter 500 mm and less, not bound in packages of pipes of 4 metres must be installed side supports, preventing rolling of the pipes.

8.2.8 the Distance between piles or racks should be at least 1 m Distance between racks in the same row should be from 0.5 to 1.0 m Distance from pile to rail road (nearest rail) shall be not less than 2.3 m.

8.3 Storage of fittings

8.3.1 Details should be stored in dry closed rooms or under a canopy provided to protect them from falling precipitation.

8.3.2 Details should be stored by stacking in piles or on racks. Not allowed to put details on steel or concrete floor without the pads, as well as on the ground and the train tracks.

Not allowed laying in piles of parts with outer permanent protective coating.

8.3.3 Height of the pile of parts, boxes of parts, containers or pallets must not exceed 1.5 m.
