Square Pipe(SHS)

Rectangular tubes are divided according to the production process: hot-rolled seamless tubes, cold-drawn seamless tubes, extruded seamless tubes, and welded tubes. Square tubes are divided by material: plain carbon steel square tubes, low alloy square tubes. 1. Common carbon steel is divided into: Q195, Q215, Q235, SS400, 20# steel, 45# steel, etc. 2. Low alloy steel is divided into: Q345, 16Mn, Q390, ST52-3, etc.

ST42 Carbon steel pipe

The tensile strength of ST42 Carbon Steel Pipe shall not be less than 42kgf/mm2, which is 420MPa.ST42 Carbon Steel Pipe is a German standard seamless steel pipe, which is widely used. German standard seamless steel pipes for general purposes are rolled from ordinary carbon structural steel, low alloy structural steel or alloy structural steel, with the largest output, and are mainly used as pipes or structural parts for fluid transportation .

Welded API 5L Line Pipe

API 5L pipe is carbon steel pipe used for oil and gas transmissions, it includes the pipes manufactured in seamless and welded (ERW, SAW). Materials covers API 5L Grade B, X42, X46, X52, X56, X60, X65, X70, X80 PSL1 & PSL2 onshore, offshore and sour services.

Welded Structural Steel Pipe

Welded steel pipes for structural use are made by double-sided submerged arc welding or high frequency welding. Welded steel pipes for structures Uses: Steel structures, bridge supports, pipes for building structures, pipes for pile foundations, etc. Since structural pipes require great pressure bearing and pressure resistance capabilities, generally the wall thickness is greater than 8mm.

API 5L X80 carbon welded steel pipe

API 5L X80 Pipe is a standardization for pipeline transportation systems within the rock oil, gas, water, and fossil fuel industries. API 5L-X80 steel is used in polar regions, wherever high toughness at low temperatures is needed.Product introduction API 5L X80 Pipe is a standardization for pipeline transportation systems within the rock oil, gas, water, and fossil fuel industries. API 5L-X80 steel is used in polar regions, wherever high toughness at low temperatures is needed.

LSAW Steel Pipe

LSAW Pipe is taking the steel plate as raw material, mold it by the molding machine, then do double-sided submerged arc welding. Through this process the LSAW steel pipe will get excellent ductility, weld toughness, uniformity, plasticity and great sealing.

Seamless Boiler Tube

General boiler tubes are mainly used to manufacture water wall tubes, boiling water tubes, superheated steam tubes, superheated steam tubes for locomotive boilers, large and small smoke tubes and arch brick tubes, etc. High-pressure boiler tubes are mainly used to manufacture superheater tubes, reheater tubes, gas guide tubes, main steam tubes, etc. of high-pressure and ultra-high pressure boilers.

Seamless Alloy Steel Tube

These Alloy steel pipes & tubes are used in different application industry like oil refineries, chemical plants, fertilizers plants, petrochemicals plants and sugar mills etc.
