Stainless steel is widely used in construction and industrial piping systems due to its excellent durability. Among them, stainless steel pipe fittings have an irreplaceable position in the industrial field. Its most prominent advantage is corrosion resistance. During the use of stainless steel pipe fittings, if they can be used and maintained correctly, their service life can be effectively extended. The following factors directly affect their long-term performance:
The impact of material on the life of pipe fittings
Stainless steel material directly affects the corrosion resistance and service life of pipe fittings. Commonly used materials such as 304, 304L, 316, and 316L differ in the content of elements such as carbon, nickel, and molybdenum, which determine their corrosion resistance and applicable environment.
The influence of forming process on performance and life
The forming process of pipe fittings determines its structural accuracy and strength. Cold extrusion and bulging processes are commonly used. Cold extrusion molding has a smooth surface, high dimensional accuracy, good local wall thickness control, and improved product durability. The bulging process is suitable for complex shapes and stable forming, but the local wall thickness will be thinned, and reasonable design is required to ensure performance.
The influence of wall thickness on connection and life
Wall thickness is the key to affecting the connection strength and impact resistance of pipe fittings. During the production process, bending and forming processes are prone to local wall thickness changes. If the wall thickness is lower than the standard, it is easy to cause leakage risks. Reasonable selection of wall thickness and control of wall thickness in elbows, U-shaped grooves and other parts are important prerequisites for long-term safe use. MTSCO has a professional quality inspection team that conducts a series of inspections and tests on pipe fittings. For welded pipe fittings, we conduct 100% ultrasonic or radiographic testing on raw materials and pipe fittings to ensure that there is no problem with the wall thickness of the pipe fittings.
The influence of solid solution process on corrosion protection and life
Solid solution treatment (about 1050℃) is a key process to improve the corrosion resistance and fatigue performance of pipe fittings. Through stress release and intergranular structure optimization, the metal toughness is improved, the hardness is reduced, and the corrosion resistance is enhanced. Pipe fittings that lack solid solution treatment are prone to early failure, affecting the life and safety of the overall pipeline system.
