Reducer pipe process and size

The reducer is also called the size head and is divided into concentric heads and eccentric heads.

First, the performance of the reducer

1. The method is expressed by multiplying the diameter of the big head by the diameter of the small head. For example, "8 x 6" means that the large head is 8 inches in diameter and the small head is 6 inches in size.

2, the pressure wall thickness is Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, Sch100, Sch120, Sch140, Sch160, XXS

3, the material is divided into carbon steel, alloy steel, stainless steel

a, carbon steel: 10#, 20#, A3, Q235A, 20G, 16Mn, ASTM A234, ASTM A105, etc.

b, stainless steel: ASTM A403, 1Cr18Ni9Ti, 0Cr18Ni9, 00Cr19Ni10, 00Cr17Ni14Mo2, 304, 304L, 316, 316L, etc.

c, alloy steel: 16MnR, Cr5Mo, 12Cr1MoV, 10CrMo910, 15CrMo, 12Cr2Mo1, A335P22, St45.8/III, A10bB

4. Execution standards: National Standard, American Standard (ANIS), Japanese Standard (JIS), British Standard (BS), German Standard (DIN), Italian Standard (UNI), etc.

5. Product use: Petroleum gas pipeline engineering, natural gas pipeline engineering, chemical plant, power plant, shipyard, pharmaceutical, dairy, beer, beverage, water conservancy, etc.

Second, the reducer production process

Re-inspection of raw materials --- cutting and cutting --- press forming --- plastic --- heat treatment --- processing groove --- finished product inspection --- surface treatment --- logo --- data confirmation --- packaging --- Storage and transportation

Third, the reducer geometry
