DETAILS

Simmer bending pipe is also called medium frequency bending pipe, its production process belongs to the scope of thermal expansion.

classification

By material:

Carbon steel: ASTM/ASME A234 WPB, WPC

Alloy: ASTM/ASME A234 WP 1-wp 12-wp 11-wp 22-wp 5-wp 91-wp 911, 15Mo3 15CrMoV, 35CrMoV

Stainless steel :ASTM/ASME A403 WP 304-304l -304H-304LN-304N

ASTM/ASME A403 WP 316-316 l - 316 - h - 316 ln - 316 - n - 316 ti

ASTM/ASME A403 WP 321-321h ASTM/ASME A403 WP 347H

Low temperature steel :ASTM/ASME A402 wpl3-wpl 6

High performance steel: ASTM/ASME A860 WPHY 42-46-52-60-65-70

Cast steel, alloy steel, stainless steel, copper, aluminum alloy, plastic, argon psychology, PVC, PPR, RFPP, etc.

1. The production method can be divided into pushing, pressing, forging, casting, etc.

2. The manufacturing standards can be divided into national standards, electrical standards, ship standards, chemical standards, water standards, American standards, German standards, Japanese standards and Russian standards.

3. According to its radius of curvature, it can be divided into long radius elbow and short radius elbow.Long radius elbow refers to the outer diameter of tube whose radius of curvature is 1.5 times, that is, R= 1.5d.Short radius elbow means that its radius of curvature is equal to the outside diameter of the pipe, which is R=1.0D.D is the diameter of the elbow and R is the radius of curvature.

4. According to the pressure grade, there are about 17 kinds of pipes, which are the same as the American pipe standard, including: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s and XS.Sch80, SCH100, Sch120, Sch140, Sch160, XXS;The two most commonly used are STD and XS.
