How are steel pipes classified according to material?
Steel pipes can be divided into non-ferrous metal and alloy pipes, ordinary carbon steel pipes, etc. according to their materials. Representative steel pipes include seamless alloy steel pipe ASTM A335 P5, carbon steel pipe ASME A106 GRB
How are steel pipes classified according to their cross-sectional shapes?
Steel pipes can be divided into round pipes and special-shaped pipes according to their cross-sectional shapes.
How are steel pipes classified according to pipe end status?
Answer: Plain tube and threaded tube (threaded tube)
How are steel pipes classified according to diameter and wall?
①Extra thick-walled tube (D/S＜10) ②Thick-walled tube (D/S=10~20) ③Thin-walled tube (D/S=20~40) ④Extremely thin-walled tube
(D/S＞40)
The diameter-to-wall ratio reflects the difficulty of steel pipe rolling production.
How are the varieties and specifications of seamless steel pipes marked?
The specifications of seamless steel pipes are expressed by the nominal dimensions of outer diameter, wall thickness and length, such as 76mm×4mm×5000mm seamless
Steel pipe refers to a steel pipe with an outer diameter of 76mm, a wall thickness of 4mm, and a length of 5000mm. But in general, only the outer diameter and wall thickness are used
Indicates the specifications of seamless steel pipes.
