Spiral seam electric welded steel pipes
Spiral seam electric welded steel pipes are manufactured in accordance with GOST 20295-85, GOST 33228-2015, GOST 31447-2012, GOST 3183-2015 and API Spec 5L.
AREA OF APPLICATION
Spiral seam electric welded steel pipes are used for the construction and repair of:
– main gas pipelines, oil pipelines and oil product pipelines transporting natural gas, oil and petroleum products;
– process and field pipelines;
– pipelines for general use;
– water pipelines transporting both industrial and drinking water.
HYGIENE REQUIREMENTS COMPLIANCE
Samples of pipes manufactured by our plant in accordance with GOST 3183-2015, both uncoated and provided with liquid epoxy anticorrosive coating, were transferred to the Service of Sanitary and Epidemiological Welfare and Public Health of the Republic of Uzbekistan. The results of laboratory tests, Report No. 20-8/1954 dated March 30, 2021, show that the quality of water in both samples meets the hygienic requirements of O’zDST 950 “Drinking water. Hygienic Requirements and Quality Control”.
The existing process equipment makes it possible to manufacture pipes in a wide range of diameters and wall thicknesses. Depending on the technical requirements of customers, pipes can be made of various steel grades and strength classes.
The presence of the certified Central Plant Laboratory equipped with modern instrumentation, testing and spectral analysis equipment, as well as hydraulic test standss and non-destructive testing equipment (X-ray, ultrasonic and magnetic testing) installed in production lines make it possible to ensure the compliance of pipes requirements of regulatory documents.
1. The outer diameter of the pipes is of 426 to 1620 mm, the wall thickness of the pipes is of 5 to 24 mm.
The standard length of pipes varies from 10,000 to 12,000 mm, as it is optimal when transporting pipes in flatbed truck or in railway open cars.
2. Pipes can be made of steels of strength group B, X42, X46, X52, X56, X60, X65 and X70 in accordance with GOST 3183-2015 or API Spec 5L, or strength classes K34, K38, K42, K48, K50, K52, K54 , K55, K56 and K60 in accordance with GOST 20295-85.
Steel grades corresponding to the above groups and strength classes in terms of mechanical properties and chemical composition are selected in accordance with GOST 14637-89, GOST 1577-83 and GOST 19281-2014.
