API 5L GR B longitudinally welded pipe
ZS Steel Tubular Products ASTM/ASME A53/SA53 ERW PIPE is a general, all-purpose pipe used in generator plants, refineries, compressor stations, natural gas transmission, and steam conduction. It is acceptable for welding, flanging, and bending.
Our steel is locally sourced, developed and produced which means our customers are assured of the highest quality standards and a local, concerned customer service presence invested in the success of your project. ZS Steel has control over every step of the pipe manufacturing process, from melt to final product. We manufacture our tubular products at several ZS Steel-based facilities that produce high-quality tubular products with low-residuals in a wide range of strength levels with superior toughness.
Electric resistance welding (ERW) refers to a group of welding processes such
as spot and seam welding that produce coalescence of faying surfaces where heat to form the weld is generated by the electrical resistance of material combined with the time and the force used to hold the materials together during welding. Some factors influencing heat or welding temperatures are the proportions of the workpieces, the metal coating or the lack of coating, the electrode materials, electrode geometry, electrode pressing force, electrical current and length of welding time. Small pools of molten metal are formed at the point of most electrical resistance (the connecting or "faying" surfaces) as an electrical current (100–100,000 A) is passed through the metal. In general, resistance welding methods are efficient and cause little pollution, but their applications are limited to relatively thin materials and the equipment cost can be high (although in production situations the cost per weld may be low).
Material Test Reports
At ZS STEEL, all test reports are computer-generated and available following final shipment. Your sales representative will be happy to discuss any of these reports in more detail with you. Reports available on line pipe manufactured to API 5L specifications:
Mechanical property tests
Fracture toughness tests
Data regarding skelp properties
Additional specific tests as requested by customer
Line pipe is hydrotested to at least the API 5L specified minimum test pressure. ZS STTEEL endeavors to hydrostatically test to 100% specified minimum yield strength (SMYS) where possible. Pipe is tested with the weld line facing up, and the trained HydroTest operator visually monitors the entire weld line during testing.
ZS STEEL provides our primary nondestructive testing for quality assurance through the ultrasonic evaluation of the entire weld for each pipe.
The performance of the equipment and the application of this procedure is the responsibility of ZS STEEL’s qualified ASNT-TC-1A, Level III. All additional ZS STEEL personnel who perform this testing are certified to ASNT-TC-1A, Level II.
ERW Black Steel Pipes and tubes are used in various engineering purposes, fencing, scaffolding, line pipes etc. These tubes & pipes are available in varying qualities, wall thickness, diameters and finishes depending on the requirement of the end-users.
In manufacturing these ERW pipes & tubes, we utilize superior quality, continuous casted, fully killed, fin-grain, control-rolled, low carbon steel. High strength corrosion resistance, high malleability, superior strength, sturdy & durability are the special features of high performance ERW steel pipes & tubes that are manufactured by us.
Being a quality conscious manufacturer & exporter, our ERW steel pipes and tubes are processed through numerous tests including a hydro-test, an ultrasonic weld inspection, bevel check, micrometer check, straightness evaluation, and ring gouge to ensure it's quality.
