Alloy pipe is defined by the steel pipe according to the production materials (that is the material), as the name suggests, it is a pipe made of alloy; while the seamless pipe is defined by the steel pipe according to the production process (seamless), which is different from the seamless pipe. Seamed pipes, including straight seam welded pipes（Welded Steel Pipe） and spiral welded pipes（Straight Seam Welded Steel Pipe）.
The material of the alloy tube is roughly: 16Mn（Q345 E355 Gr.50seamless Steel Tube）, 27SiMn, 40Cr（40cr Alloy Tube）, 42CrMo, 12Cr1MoV, T91（Astm T91 Boiler Tube）, 35CrMo, 15CrMo, 20G, 15CrMoV, 45CrNiMo, etc. It is mainly used on high-pressure and high-temperature pipelines and equipment such as power plants, nuclear power, high-pressure boilers, high-temperature superheaters and reheaters. It is made of high-quality carbon steel, alloy structural steel and stainless heat-resistant steel. (extrusion, expansion) or cold rolling (drawing).
Alloy steel pipe is a kind of economical section steel, which is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes, automobile transmission shafts, bicycle frames and steel scaffolding used in construction. Using alloy steel pipe to make ring parts can improve the utilization rate of materials, simplify the manufacturing process, save materials and processing time, such as rolling bearing rings, jack sets, etc., which have been widely used in steel pipe manufacturing. Alloy steel pipe is also an indispensable material for various conventional weapons, and the barrel, barrel, etc. must be made of steel pipe. Alloy steel pipes can be divided into round pipes and special-shaped pipes according to the shape of the cross-sectional area. Since the area of the circle is the largest under the condition of equal perimeter, more fluid can be transported with a circular tube. In addition, when the ring section is subjected to internal or external radial pressure, the force is relatively uniform, so most steel pipes are round pipes.Carbon Seamless Steel Pipe Precision Steel Tube 1045 Seamless Steel Tube Astm A106 Gr.
