Seamless steel pipes are perforated from whole round steel, and steel pipes without welds on the surface are called seamless steel pipes. According to the production method, seamless steel pipes can be divided into hot-rolled seamless steel pipes, cold-rolled seamless steel pipes, cold-drawn seamless steel pipes, extruded seamless steel pipes, and top pipes. According to the cross-sectional shape, seamless steel pipes are divided into two types: round and special-shaped. Special-shaped pipes have square, elliptical, triangular, hexagonal, melon-shaped, star-shaped, and finned pipes. The maximum diameter is 900mm and the minimum diameter is 4mm. According to different uses, there are thick-walled seamless steel pipes and thin-walled seamless steel pipes. Seamless steel pipes are mainly used as petroleum geological drilling pipes, petrochemical cracking pipes, boiler pipes, bearing pipes, and high-precision structural steel pipes for automobiles, tractors, and aviationStandard | ASTM A106, ASTM A53, API 5L Gr.B, DIN17175,DIN1629 | |||

Seamless Steel Pipe,as the name suggests,is a pipe without a seam or a weld-joint.
Seamless Steel Pipes 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,powders and
masses of small solids
The production of our seamless steel pipes is tightly regulated and all of the pipes we produced
have been fuly tested to international standards to ensure we only supply the hightest products.
Advantage:
1) Hot rolled and cold drawn technique, producing more large diamter
2) Cutting customized length on production line with tolerance +/-5mm
3) Bevel is free
4) Packing the products as per your requirement
Packing and Shipping:
1. In bundle with 8-9 steel stripes for small diameter steel pipe
2. Wrapped the bundle with water-proof bag and then bundled by steel stripes and nylon lifting belt in both ends
3. Loose package for big diameter steel pipe
4. As per customer's requirement
