What is the Application of Compressed Air Porting Block in Pneumatics?

The Compressed Air Porting Block, also known as the steam distribution drum in pneumatics, is one of the main support equipment for steam boilers. Various pipes are used for distributing steam produced during the boiler's operation. The gas distribution block is a pressure-bearing device and belongs to a pressure vessel.

The primary function of the gas distribution block is steam distribution; therefore, there are several ports on the gas distribution block in different locations for connecting the main steam valve and the steam distribution valve of the boiler to distribute steam within the gas distribution block.

Main Components of Compressed Air Porting Block

  • Steam distribution valve seat
  • Main steam valve seat
  • Safety valve seat
  • Drain valve seat
  • Pressure gauge seat
  • Thermometer seat
  • Head material
  • Shell
  • Flange Q235-A/B 20#, 16MnR
  • Specification model ф159 to ф1500
  • Working pressure 1 to 2.5 megapascals
  • Working temperature: 0 ~ 400 ℃
Compressed Air Porting Block in Pneumatics

The function of the gas distribution block involves steam, hot and cold water, and compressed air. When the environment is steam, it must be designed according to the "pressure vessels regulations" and the diameter, material, and thickness of the cylinder should be determined. The cylinder diameter should be 2 to 2.5 times the diameter of the largest connecting pipe, which can generally be determined based on the fluid flow rate in the cylinder.

The seamless pipe material is 10-20#, Q235B, 20#, and 16MnR plate. The coil and number of connecting pipes are determined by engineering design.

Compressed air porting block systems can be installed and set up 50% faster than traditional methods. The unique design of the collet lock keeps the pipe secure and safe without deforming or restricting flow.

Connections are also completely separable, reducing system downtime during maintenance and making alterations or expansions of the systems quick and easy.
