JIS G3445 Carbon Steel Mechanical Tube
JIS G3445 carbon steel mechanical pipe is suitable for machinery, automobiles, bicycles, furniture, appliances and other mechanical parts.
ASME SA179 seamless steel pipe is a low-alloy high-strength steel with excellent corrosion resistance and high-temperature performance. It is suitable for manufacturing equipment components in harsh environments, such as drill pipes, chemical equipment, and boilers. In heat exchangers, ASME SA179 U-shaped elbow heat exchanger tubes can withstand high temperature and high pressure working environments, and at the same time have good heat conduction properties and can effectively transfer heat from one medium to another.
Technical Parameters
Outer diameter: 12.7-38 mm
The bending radius is from 1.5 times the outer diameter to 1250 mm. The outer diameter is over 28mm,
The minimum bend radius can be further discussed.
Straight pipe length is the shortest 1000mm
Straight pipe length up to 12000mm
The bending radius is below 1000mm and heat treatment is required.
