2. TECHNICAL REQUIREMENTS

2.1. Pipe manufactured in accordance with the requirements of this standard for technological regulations approved in the prescribed manner.

Pipes are made from lead brands C1 and C2 with the chemical composition according to GOST 3778.

(Changed edition, Rev. N 1).

2.2. Surface of the pipe must be clean, smooth, without cracks, captivity, scratches, pits, and nonmetallic inclusions. Allowed some minor surface defects, oxide films, minor imprints, if they are not in the sweep output tubes for maximum deviations in size.

2.3. The pipe ends should be cut smoothly and should not have a significant Burr.

2.4. (Deleted, Rev. N 1).

3A. ACCEPTANCE RULES

3A.1. Pipes take by the parties.

The party should consist of pipes of the same size made of lead to one brand and feature a document about quality that contains:

trademark or the name and trademark of manufacturer;

the symbol of the pipes;

batch number;

the designation of this standard.

3A. 2. Check the outer surface, control the size and shape subjected to each pipe.
