Methods of Heating

Buttweld fittings are pipe fittings used to change the pathway of a pipeline (elbows), reduce/increase the pipe bore size (reducers), branch (tees, cross) or blind a pipeline (butt weld cap). ASME B16.9 (and MSS-SP 43) Buttweld fittings are used for piping systems above 2 inches in diameter, whereas

Stainless steel flanges are pipe fittings with stainless steel as the main material, which have good corrosion resistance, strong rigidity and not easy to wear. Therefore, it is widely used in chemical, petroleum, construction, shipbuilding, medicine, food manufacturing and other industries. In orde

PIPE ELBOW MANUFACTURING PROCESSButtweld elbows 45 and 90 degrees can be manufactured in different ways, the main ones are the “mandrel process” and the “cold forming” (other methods are the elliptical forming and the double-seam welding method).Mandrel ProcessCold forming

Advantages of Stainless steel flang: 1. Stainless steel flange is acid and alkali resistant, corrosion resistant, and fireproof. 2. Easy to use and install, in one step.3. Diversified scope of application, suitable for various pipelines. 4. Long application life, not easy to age. 5. Low carbon and environmental protection, high durability.

The seamless steel pipe is hollowed out in the middle, which is mainly used to transport fluids, such as gas, natural gas, oil and solid materials. Compared with solid steel pipe, seamless steel pipe is lighter in weight and is a kind of economical cross-section steel. Seamless steel pipe is widely used in the manufacture of mechanical parts and structural parts, such as automobile transmission shafts, oil drill pipes, and steel scaffolding used in construction.
