Seamless steel pipe specifications and wall thickness

Seamless steel pipe specifications and wall thickness
The specifications and wall thickness of seamless steel pipes vary depending on application scenarios and types. Common types are as follows:

Hot rolled seamless steel pipe. The outer diameter is usually greater than 38mm, and the wall thickness is between 3~80mm.
Cold rolled seamless steel pipe. The outer diameter can be up to 6mm and the wall thickness can be up to 0.25mm.
High pressure seamless steel pipe. The outer diameter ranges from 10 to 159mm, and the wall thickness ranges from 2 to 45mm.
Precision seamless steel pipe. The outer diameter ranges from 10 to 377mm, and the wall thickness ranges from 1 to 25mm.
stainless steel pipe. The outer diameter range is from 6 to 530mm, and the wall thickness is from 0.5 to 15mm.
In addition, there are ordinary seamless steel pipes, alloy seamless steel pipes, structural seamless steel pipes, hydraulic seamless steel pipes, etc., and their specifications and wall thicknesses are also different. For example, the wall thickness of ordinary seamless steel pipes usually ranges from 1.5mm to 10mm; the wall thickness of precision seamless steel pipes usually ranges from 0.6mm to 6mm; the wall thickness of alloy seamless steel pipes usually ranges from 2mm to 30mm; the wall thickness of structural seamless steel pipes The wall thickness is usually from 3mm to 40mm; the wall thickness of hydraulic seamless steel pipe is usually from 4mm to 50mm. These specifications ensure that seamless steel pipes can be adapted to a variety of industrial needs and standards
