Analysis of five connection methods for thin-walled stainless steel pipes
Analyzing the connection methods of thin-walled stainless steel pipes, common connection methods in the Chinese market include:
1. Dual compression connection:Insert the piping into the pipe fitting and use a special installation tool to clamp the pipe wall into a hexagonal shape, and the internal sealing ring also becomes a hexagonal shape.
2Conical thread typeconnect:By directly tightening the pipe fittings or pipes, the two connectors with conical pipe threads at the inner and outer interfaces are tightened, and the connection effect is achieved through pressure sealing of the connection thread (similar to traditional threaded galvanized steel pipe sealing).
3Socket welding connectionInsert the piping into the socket type fitting, and perform a circular argon arc welding between the fitting and the piping to seal and complete the piping connection.
4Groove connection:Grooved pipe fitting connection technology, also known as clamp connection technology, has become the first technology for liquid and gas pipeline connection at present. Although this technology was developed later in China than abroad, it was quickly accepted by the domestic market due to its progressiveness technology.
5Flange connection:Perform circular argon arc welding between the flange and the piping, fasten with quick clamps or bolts to ensure that the sealing gasket between the flanges plays a sealing role, and complete the piping connection.
Thin walled stainless steel pipes will be widely popularized in the next few years, applied in civil building cold and hot water pipelines, gas, chemical, pharmaceutical and other industries. The product materials are superior, and the production and installation processes are advanced, reaching the international advanced level of the pipe fitting industry. The hygiene performance of the product meets the requirements of drinking water standards in other developed countries such as Europe, America, Japan, and so on.
With the widespread promotion of thin-walled stainless steel pipes by the country, they will inevitably become products in the pipeline industry. The Chinese Science and Technology Commission has been working for a long timeIn the notice of "Promoting the Application of High Diameter to Wall Ratio and High Precision Stainless Steel Medium and High Pressure Water Supply Pipes and Supporting Pipe Fittings and Special Technologies" in 2001, thin-walled stainless steel pipes were fully recognized, and it was believed that the promotion and application of this technology and product would be of great significance for improving and ensuring water quality. On January 3, 2003, the Ministry of Construction also proposed in Jian Zhi (2003) No. 4 "Selection of Pipe Fittings and Meters 2" that thin-walled stainless steel pipes should be given priority (SUS316 should be used for buried materials and SUS304 should be used for open installations). The pipe fittings for thin-walled stainless steel pipes have been included in the 2002 National Torch Plan project.
Multiple connection methods for thin-walled stainless steel pipes seize the market opportunity and have an advantage in price; The product has the characteristics of wide adaptability, high technological content, full functionality, low price, good usage effect, novelty and uniqueness, and convenient installation.
With the improvement of national living standards, people's consumption and health awareness will become increasingly strong, and the improvement of quality of life will inevitably bring products into popularization and inevitability.
