- BUTTWELD FITTINGS IN PIPINGButtweld 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, whereasProduct knowledge December 01, 2021
- Precautions for Welding Stainless Steel FlangesStainless 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 ordeProduct knowledge November 11, 2021
- PIPE ELBOW MANUFACTURING PROCESSPIPE 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 formingProduct knowledge December 22, 2021
- Advantages of Stainless Steel FlangeAdvantages 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.Product knowledge November 18, 2021
- SEAMLESS STEEL PIPEThe 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.Product knowledge December 09, 2021
- SEAMLESS VS WELDED BW FITTINGSSEAMLESS VS WELDED BW FITTINGS Butt weld fittings are available in seamless and welded execution (seamless for bore sizes below 24 inches, welded for sizes above 24 inches). Seamless buttweld fittings have no seam welds and are therefore considered superior to welded BW fittings (a weld is always aProduct knowledge January 26, 2022
- PIPELINE SYSTEMSPipe selection and wall thicknessSteel pipe is required in the majority of oil and gas production and pipeline applications. ASME A53 and A106 and API 5L seamless, electric resistance welding (ERW), and submerged arc welding (SAW) steel pipe are commercially available and most commonly used in pipeProduct knowledge November 26, 2021
- Application of Welded PipesWelded pipes have low production costs, common raw materials, short production cycles, and can be manufactured into different lengths according to requirements, so they are used in large quantities.Welded steel pipes are widely used in many fields because of low cost and high efficiency.Product knowledge December 02, 2021
- BUTTWELD ELBOW 45/90/180 DEG.BUTTWELD ELBOW 45/90/180 DEG.ASME B16.9 buttweld elbows are manufactured in a wide range of dimensions (combinations of outside diameter and wall thickness) to fit ASME B36.10 and ASME B36.19 carbon, alloy and stainless steel pipes of any size between 2 and 48 inches (and above).Buttweld elbows beloProduct knowledge December 08, 2021
