Various pipe fittings are used for waterway construction.
Stainless steel pipe fittings mainly include equal diameter joint, reducing joint, adjustable joint, 90 ° elbow A(B), external thread tee adapter, reducing tee, internal thread tee adapter, 90 ° (internal) external thread adapter, 45 ° elbow A(B), equal diameter tee, equal diameter cross, (internal) external thread adapter, moving screen adapter, pipe cap, pipe bridge, flange adapter, etc.
Take equal diameter joint and 90 ° equal diameter elbow as an example.
The specific production process is similar, with subtle differences. For example, a constant diameter joint is a long water pipe. After cutting according to the equidistance, remove the burr, reach the water forming machine, water forming once. It is understood that the internal water pressure of the small water forming machine is about 70 tons, and the large water forming machine is 700 tons.
Straight diameter stainless steel pipe fittings.
90 ° equal diameter elbow includes manually operated machine and automatic elbow for water rise. The manual elbow machine mainly uses the machine to bend the cut equal distance pipe, and then forms the water rise on the water rising machine. The automatic elbow water rise is mainly to manually put the cut equal distance pipe into the tank. After the machine is started, the mechanical arm is automatically taken out and placed in the designated position to improve the elbow water and high work efficiency.
90 ° elbow fittings.
Domestic stainless steel pipes have national standard I series, national standard II series, European standards and other products. The national standard II series and European standards are only used in a few places in China, and more or more national standard I series are used.
Thin-walled stainless steel pipe fittings were released in 2011, and part of the GBT1928.1-2011 stainless steel pipe fittings implemented in 2012 was the standard for pipe fittings. This standard specifies pipe fittings with diameter less than DN100 and nominal pressure no greater than PN16.
Part of stainless steel clamping pipe fitting assembly: clamping pipe fitting.
The international pipe flange standard has two main systems, namely, the European pipe flange system represented by German DIN (including the former Soviet Union) and the American pipe flange system represented by the American ANSI pipe flange. In addition, there are Japanese JIS pipe flanges, but they are generally only used for utilities in petrochemical plants and have little international impact. Now the national pipe flange is introduced as follows:
1. European system pipe flanges represented by Germany and the Soviet Union.
2. The American system pipe flange standard represented by ANSIB16.5 and ANSIB16.47.
3. British and French pipe flange standards, the two countries have two casing flange standards.
In summary, the internationally accepted pipe flange standards can be summarized as two different and non-exchangeable pipe flange systems: one is the European pipe flange system represented by Germany; the other is represented by the United States. American pipe flange system.
IOS7005-1 is a standard promulgated by the International Organization for Standardization in 1992. It is actually a pipe flange standard formed by merging the two casing flanges of Virtue.
