Stainless steel material is used to produce various products. Pipes being one of them. They are divided into subcategories. ASTM A312 Stainless Steel Pipe is one such grade that is heavily cold worked welded stainless steel pipe. It is designed to be used in high temperature and high services where general corrosion is commonly seen. They are manufactured either in welded, seamless, or coldworked form. ASTM A312 Pipe has a diameter ranging from ⅛ inches to 30 inches in size. The thickness of these pipes ranges from schedule 10s to schedule 80. Filler metals are not required to be added for the welding process.
A312 pipe material is free from contaminated iron filling and oxide scaling. Incase the mentioned pipe is bright annealed then there is no requirement for surface finishing, blasting, or pickling. However,at customers' request, these pipes can be passivated. ASME SA312 can be individually quenched or rapidly cooled in water post heat treatment. The electric fusion welded pipes are less susceptible to localized corrosion when compared to other pipes. The low carbon content of these pipes makes them easy to form and weld. ASTM A312Mis available in 1.2 mm to 2 mm thickness. The pipe is available in regular sizes of 3 meters, 6 meters, and 10 meters. The brushed and satin finished pipes are used in malls and various other places due to their aesthetics.
ASTM A312 Seamless Stainless Steel Pipe is pushed or pulled to form a raw material billet which is used to produce seamless pipes. The products supplied by us are passed through various tests such as hydrostatic test, flattening test, straightness, and surface quality test and so on. ASTM A312 Tubing has a high yield and tensile strength. They also display high resistance to pressure. They have a melting point of 1400 degrees C and a density of 8.0 g/cm3. These pipes can resist high mechanical stress and are said to be reusable. The 312 pipes supplied by us are made as per the international standards and are supplied with utmost care.
