Stainless Steel End Caps Fittings is available in different grades, materials, sizes, finishes, etc. The industry is having a professional team that is looking after the entire production of the Stainless Steel Coupling Fittings that is assuring in supplying the defect-free product. Stainless Steel Coupling Fittings is available in different grades, materials, sizes, finishes, etc. The industry has a specialist team that oversees the entire manufacturing of the Stainless Steel Tee Fittings and ensures that the product is defect-free. Stainless Steel Tee Fittings come in a variety of grades, materials, sizes, and finishes. The industry has a specialist team that oversees the entire manufacturing of the Stainless Steel Elbow Fittings and ensures that the product is defect-free. As NPT connections are assembled, it will reduce the possibility of leakage.Elbow Fittings are made using cutting-edge technology, cutting-edge equipment, raw material quality requirements, and industry standards. The standard thread for tapered groove is National Pipe Thread (NPT). The tapered groove allows the pipes to be easily assembled with threaded fittings. Threaded end(TE) pipes are pipes with tapered groove that cuts into the ends of pipes. Pictures of bevel end are illustrated in the product literature pdf file below. Bevel end pipes are usually used for butt weld fittings and flanges where they can be directly welded to each other. However, pipes with non-standard angles can also be produced. It also has a root face of 1.6mm (☐.8mm). It is also suitable for socket weld fittings and flanges.īevel end (BE) pipes are pipes that have a standard angle of 30° (+5°/-0°) on the pipes end surface. Generally, plain end pipes are used for small diameter pipe systems. Plain end (PE) pipes are pipes with unfinished ends. There are 3 main types of pipe ends for stainless steel pipe, namely plain end (PE), bevel end (BE) and threaded end (TE). And it also prevents chromium from being depleted, thus, it can still form the chrome oxide layer on the pipe surface. The lesser the carbon content the stainless steel has, the greater it is in weldability. The meaning of “L” designation in SS316L grade is that carbon content is restricted to 0.03% where the normal carbon content in stainless steel SS316 is 0.08%. It also provides higher tensile strength at elevated temperature. In addition, SS316/316L material will reduce the tendency of the material to crack after welding. The nickel and molybdenum content provides great corrosion resistance in corrosive surroundings, such as salt water or chloride environments. The molybdenum content in stainless steel pipe is around 2.0% to 3.0%, while nickel content is around 11% to 14%. SS316/316L is a chromium-nickel-molybdenum bearing austenitic stainless steel. This allows it to form an invisible chrome-oxide layer by reaction with oxygen. Stainless steel pipes contain at least 10.5% of chromium. The minimum tensile strength for stainless steel pipes is 515 N/mm² while minimum yield strength at Rp 0.2% at 205 N/mm². The welding should be selected in accordance with DIN EN 1600 and DIN EN 12072 part 1 taking into account the type of application and the welding technique.Ĭhemical composition for ASTM A312 / ASME SA312, TP316/TP316L dual grade seamless stainless steel pipe is as per the table below. Pipes made of TP316 and TP316L are suitable for arc welding using usual techniques. There are three types of end connections for stainless steel pipes: plain end (PE), bevel end (BE), and threaded end (TE).Ī bend radius of 3x the external tube diameter, is recommended for the tube’s cold bending using tube benders or by manual hand bending. The unit SCH refers to the variation of thickness. The unit used in stainless steel pipes is Inch NB size range and thickness is in schedules (abbreviated as “SCH”). Stainless steel pipe is available in one finishing, namely annealed and pickled. SS316 pipes are most supplied in high performance fluids application for its great corrosion resistance and for its ability to withstand higher pressure. The material of stainless steel pipe is available in dual grade which is SS316 / 316L which allows dual usage of tubes. Seamless cold drawn stainless steel pipes are made in accordance to ASTM A312 TP316 / 316L standards.
