Butt Weld Pipe Fittings

Pipe fitting is work that involves the installation or repair of pipes or tubes. Pipes and tubes are necessary for a wide range of reasons. We are passionate about elbows, tees, reducer … Pipe elbows  >> Steel elbow is used to be installed between two lengths of pipe or tube allowing a change of direction,usually these carbon steel elbows distinguished by connection ends. +  Long radius  +  Short radius Pipe bending  >> Pipe bend can be made of variety materials,like carbon steel,alloy steel,stainless steel,low temperature steel or high performance steel,etc. + 180 degree bending     +  ASTM API 5L Gr.B bends   Pipe Tees  >> We can provide seamless tube tees and welding tube tees,which can also be divided into straight tees and reducing tees.Usually,the pipe tees have the same inlet and oulet sizes. +  Reducing tee     +  Barred Tee   ...

Japanese Industrial Standards specifies the standards used for industrial activities in Japan. The standardization process is coordinated by Japanese Industrial Standards Committee and published through Japanese Standards Association. JIS G3429  Seamless steel tubes for high pressure gas cylinder. In the Meiji era, private enterprises were responsible for making standards. However, the Japanese government did have standards and specification documents for procurement purposes for certain articles, such as munitions. These were summarized to form an official standard old JES in 1921. During World War II, simplified standards were established to increase matériel output. The Industrial Standardization Law was enacted in 1949, which forms the legal foundations for the present Japanese Industrial Standards. The Industrial Standardization Law was revised in 2004 and the  JIS  mark product certification system was changed. Standards are named like “ JIS  X 0208:1997″, whe...

American National pipe ( NPT , NPS), Like British Standard Pipe ( BSP ), is designated by trade size, rather than actual diameter, as shown in the table below. NPT Thread – American Standard Taper Pipe Thread (ANSI/ASME B1.20.1), Taper 1:16 Thread Form Data – Basic Dimensions of American National Standard Taper Threads, NPT (National Pipe Tapered) There are two basic types of National pipe threads: NPT: National Pipe Taper NPS: National Pipe Straight NPT threads are also sometimes referred to as MIP (Male Iron Pipe) FIP (Female Iron Pipe) IPT (Iron Pipe Thread) FPT (Female Pipe Thread) MPT (Male Pipe Thread) Note that these references are somewhat casual, and might possibly be used in reference to NPS instead of NPT. Both NPT and NPS have the same thread angle, shape, and pitch (threads per inch). However, NPT threads are tapered and NPS threads are straight (parallel). Both threads have a 60° included angle and have flat peaks and valleys (this is a Sellers thread form). If you’ve wor...
