Production | Pipe for general service

The main features:
Pipes are manufactured from coiled steel that ensures a narrow range of chemical composition, low percentage of harmful impurities (sulfur, phosphorus) and inclusions, minimum difference in wall thickness in the final pipe.
The set precision of thickness of coiled steel, out-of-the-state technology and high precision of rolls ensure much better geometrical parameters in the final pipe compared to the same seamless pipe. That allows us to make precise calculations of the water/gas pipelines and as a result to lower the cost.
100% of welded seam is annealed that ensures weld seam structure normalization and equal strength both of the weld seam and the base material.
The pipes are manufactured from the following steel groups: 3сп, 10, 20, 09Г2С, 09ГСФ.
The pipe withstands the pressure not less than 6.0 МPa (60 kgf/сm²) for the diameter 73.0-89.0 mm., not less than 3.0 МPa (30 kgf/сm²) for the diameter 108.0-426.0 mm.
As agreed with the customer, the pipe of intermediate sizes and grades can be manufactured.
