Carbon Seamless Steel Pipe
Seamless steel pipe, as the name suggests, is a pipe without a seam or a weld-joint. Seamless steel pipe is a tubular section or hollow cylinder, usually but not necessarily of circular cross-section, used mainly to convey substances which can flow — liquids and gases (fluids), slurries, powders and masses of small solids.

Certificate: ISO 9001, ISO 14001, ISO 45001, CE
Out Diameter: 1/8 – 36inch (10.3-914.4mm)
Wall Thickness: 1.25 – 50mm
Length: Random Length, Fixed Length, SRL, DRL
Steel Grade:
ASTM A53/ASTM A106: GR A, GR B, GR CASME
ASME A500: GR.A, GR.B, GR.C, GR.D
Test Required:
Chemical Analysis, Mechanical Test, Visusal Inspection , Tension Test, Dimension Check, Bend Test , Flattenting Test, Impact Test, DWT Test, NDT Test, Hydrostatic Test, Hardness Test

ERW/HFW Pipe
The High-Frequency Longitudinal Seam Welded Steel pipe is also called ERW steel pipe, it’s manufactured by cold-forming a sheet of steel into a cylindrical shape. Current is then passed between the two edges of the steel to heat the steel to a point at which the edges are forced together to form a bond without the use of welding filler material.
MAIN CHARACTERISTICS OF ERW STEEL PIPES:
High-security welding seam: as a result of special welding method of melting of the parent metal together without filler metal, the welding property is better and the welding seam is much smaller than spiral welded pipes.
Cost effective and short production period
A wide range of thickness/diameter ratio, covering hundreds of specification
In –line inspection and testing
APPLICATION OF ERW PIPES:
Casing and tubing: lined inside drilling well. Seamless pipes use to be the only choice for lining pipes inside drilling well, but as the worldwide acknowledgement of ERW pipe’s high-quality weld seam and the cost-effective, more and more projects have been choosing ERW instead of seamless pipe.
Constructional structural pipes(round, square and rectangular): round, square and rectangular ERW structural pipes are widely used in frameworks of shopping centres, theatres, airports, bridges, workshops etc.
Low-pressure flow transmitting: ERW pips are also used in water supply; cooling water supply for plants and equipment; low pressure thermal distributing; coal slurry transportation and more. Pipes for raw materials in the manufacturing industry: automobile vent-pipe; low and intermediate pressure boiler pipes; bulk matters transportation pipes. Other application: piling pipes, furniture fabricating and more.
