Electrowelded steel pipes with a spiral seam

Steel spiral pipes are intended for pipelines, boiler installations, designs and other technical purposes.

Steel spiral pipes are made on the basis of mentioned below technical requirements, on condition of existence of isolation or its absence on internal and external surfaces:

• Covered with polyethylene;
• Coated;
• Covered with epoxy;
• Covered with concrete;
• Covered with fiber glass matter;

These pipes depending on diameter and a form of isolation can be used in lines of gas distribution, in lines of drinking and technical water, in the base, in the industry, in lines of a high pressure and in other places.

Pipes which are made by the enterprise pass in internal laboratories test a water stream under the pressure of 120 A.d. and test for ultrasound x-ray devices. Depending on appointment, the following requirements are imposed to the spiral pipes made of different types of steel sheets:

• high resilience;
• resistance to a high pressure;
• durability;
• elasticity.

For compliance to requirements and competitiveness in the internal and world markets, the quality standards of production of the USA, Germany and Russia are taken as a basis.
