Application of 316 ultra-high pressure precision stainless steel pipe

316 ultra-high pressure precision stainless steel pipe is made of high-grade stainless steel material. After hardening, it has high strength and corrosion resistance. It can transmit liquid and gas without leakage, and the pressure can reach 1034MPa. With the development of today's technology, ultra-high-pressure precision pipes are widely used in the industry.

316 ultra-high pressure precision stainless steel pipe is highly fatigue-resistant and not easy to burst. The maximum length of 1/4-inch high-pressure pipe is 7.9 meters; the maximum length of 3/8-inch and 9/16-inch high-pressure pipe is 7.9 meters. It is widely used to transport various liquids and gases, such as air compressors, high-pressure water jets, high-pressure water cutting, high-pressure cleaning machines, etc. The following is a detailed introduction to its application:

1. Air compressor pipeline

316 ultra-high pressure precision pipe is used as the pipeline of the air compressor, and it must withstand high pressure. Air compressor pipelines generally use double clamping connection, because it is convenient to achieve double clamping and firm sealing effect. It has the characteristics of shock resistance, pressure resistance, and corrosion resistance for compressed air, vacuum, nitrogen, inert gas, etc. In addition, the use of 316 ultra-high pressure precision stainless steel pipe as the air compressor pipeline has high strength, which is 3 times that of copper pipe and 8 to 10 times that of PPR pipe, and can withstand the impact of high-speed fluid at 30 meters per second. It can also work safely for a long time at a temperature of -270℃-400℃. Whether it is high temperature or low temperature, no harmful substances will be precipitated. The material performance is quite stable and has good ductility and toughness.

2. Oil pipeline

The oil pipeline is the biggest consumer of stainless steel pipes. In the equipment manufacturing, oil production, refining, and transportation of the oil industry, stainless steel pipes play an important role. As the transport of liquids such as oil, 316 ultra-high pressure precision stainless steel pipe must have high-pressure resistance, corrosion resistance, high and low-temperature resistance, and other properties. After testing, 316 ultra-high pressure precision stainless steel pipe has the advantages of high pressure without leakage, high precision, high finish, cold bending without deformation, expansion, flattening without cracks, etc., which can fully withstand it.

In terms of welding, the weld is the weak link of oil pipes, and the quality of the weld directly affects the safety of pipelines and even transmission pipelines. We conduct 100% radiographic inspection on all welds. The welds must be free of defects such as incomplete penetration, weld inclusions, undercuts, and cracks to ensure the stability of the welded joints under low-temperature conditions.
