Thermal insulation pipe

he anticorrosive heat insulation elbow is bent by using a set of bending dies, and is divided into two processes, namely, cold simmer and hot push. No matter what kind of machine equipment and pipeline, most of them are used to bend pipe, mainly used for oil, gas, liquid and so on. The main production equipment of anti-corrosion and heat preservation pipe bending machine is pipe bending machine, pipe bending machine can be roughly divided into CNC pipe bending machine, hydraulic pipe bending machine and so on. According to the requirements of function, diameter and wall thickness, hot bending equipment and control techniques, different hot bending processes are selected and suitable hot bending process parameters are worked out to ensure the qualified bending pipe.

Classification of anticorrosive insulation elbow

1.

Carbon steel: ASTM/ASME A234 WPB, WPC

Alloys: ASTM/ASME A234 WP 1-WP 12-WP 11-WP 22-WP 5-WP 91-WP911 15Mo3 15CrMoV, 15Mo3

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

ASTM/ASME A403 WP 316-316L-316H-316LN-316N-316Ti

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

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 leaching, PVC, PPR, RFPP (reinforced polypropylene), etc.

2. the production methods can be divided into push, press, forge, casting and so on.

3. According to the manufacturing standard, it can be divided into national standard, electric standard, ship standard, chemical standard, water mark, American standard, German standard, Japanese standard, Russian standard, etc.

4. according to its radius of curvature, it can be divided into long radius elbow and short radius elbow. Long radius elbow refers to its radius of curvature equal to 1.5 times the outside diameter of the pipe, that is, R = 1.5D; short radius elbow refers to its radius of curvature equal to the outside diameter of the pipe, that is, R = 1.0D. (D is the elbow diameter, R is the radius of curvature).

5. There are about seventeen kinds of pressure classes, which are the same as the American pipe standards: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, SCH100, Sch120, Sch140, Sch160, XXS; the two commonly used ones are STD and XS.
