Can Stainless Steel Pipe Be Used For Natural Gas

Stainless steel pipes can be used for natural gas. Steel pipe is the main material of the pipeline. Natural gas transportation steel pipes are special metallurgical products formed by deep processing of plates (belts). For natural gas pipelines, strength, toughness and weldability are the three most basic quality control indicators.


According to its application, natural gas transmission pipeline can be divided into three types: gas collection pipelines, gas transmission pipelines, and gas distribution pipelines. Modern gas collection pipelines and gas transmission pipelines are made of steel pipes connected by electric welding . There are various types of steel pipes , such as seamless pipes , spiral seams, and straight seams . Seamless pipes are suitable for pipes with a diameter of 529 mm or less, and spiral seams and straight seams are suitable for large-diameter pipes. The gas distribution pipeline is the pipeline from the urban pressure regulating and metering station to the user branch line, with low pressure, many branches, dense pipe network and small pipe diameter. Generally, steel pipe is used.


The stainless steel corrugated pipe is installed in the liquid transportation system as a flexible pressure-resistant pipe fitting to compensate the mutual displacement of the pipe or the connecting end of the machine and equipment, absorb the vibration energy, and can play the role of vibration reduction and noise reduction. It has many characteristics such as good flexibility, light weight, corrosion resistance, fatigue resistance, high and low temperature resistance.


Stainless steel corrugated pipe have many advantages as domestic natural gas pipeline:

1. High aging resistance. Stainless steel under natural conditions is not prone to brittle, hardening, fracture and other aging phenomenon.

2. High temperature resistance. Stainless steel corrugated pipe can withstand high temperature, under fire will not soften, fire.

3. It is firmly installed. Stainless steel corrugated pipe is connected by threaded thread at the pipe connection, which can prevent accidental falling off.

4. Corrosion resistance. Stainless steel corrugated pipe are usually made of 304 stainless steel. The common corrosive liquid can resist, and the PVC protective coating also has a certain fire-retardant and anti-corrosion effect.

5. Long service life. Compared with rubber hose, the service life of stainless steel corrugated pipe is much longer.

6. Easy to install. The stainless steel corrugated pipe, due to its dense and deep corrugation, has good flexibility, can be bent at will, and is easy to install.
