Diameter, wall thickness. standard. Professional steel pipe manufacturers direct sales of thick-walled steel pipes, seamless thick-walled, straight-seam thick-walled steel pipes
Thick-walled steel pipe specification range
The outer diameter of thick-walled steel pipes usually exceeds, and steel pipes with wall thickness exceeding The maximum seam can be reached, the wall thickness can be reached. The maximum double weld seam can be reached.
Uses of thick-walled steel pipes
Thick-walled steel pipes are mostly used in large-scale steel structure construction as the main support part, such as bridge piling, submarine piling, and high-rise building piling. Its material is generally used. It will also be used in areas with lower temperatures.
Thick-walled steel pipe production process
The production process of thick-walled steel pipes generally includes hot rolling, hot coiling, casting and other production methods! Thick-walled steel pipes are mostly seen in the double-sided submerged arc welding production process. The products are bent, Multiple processes such as seam jointing, internal welding, external welding, straightening, and flatheading meet the standards of the American Petroleum Institute.
Thick-walled steel pipe production process
Tube blank inspection, peeling inspection, heating, perforation, pickling, grinding, lubrication, air-drying, welding head, cold drawing, solid solution treatment, pickling, pickling, passivation inspection, cold rolling, degreasing, cutting, air-drying, internal polishing, outside Polishing Inspection Marking Finished Product Packaging

Thick-walled Steel Pipe Weight Formula< br/>[(Outer diameter wall thickness)*Wall thickness]*./meter (weight per meter)
Calculation method of steel pipe pressure
One way to know the outer diameter specifications of seamless steel pipes Calculation method for thickness to withstand pressure (different steel pipe materials have different tensile strengths)
Pressure (wall thickness** steel pipe material tensile strength)/(outer diameter* coefficient)
Two ways to know that seamless pipes have no Calculation method of wall thickness based on outer diameter and pressure of seamed steel pipe
Wall thickness (pressure*outer diameter*coefficient)/(*tensile strength of steel pipe material)
Expression method of pressure coefficient of three steel pipes
