Which Type Of Steel Pipe Fittings Used For Connecting API 5L Line Pipe?

Which type of steel pipe fittings used for connecting API 5L line pipe?

 

Customer often ask me that what pipe fittings used for connecting his pipes.obviously,different pipe can be connected with different pipe fitting and pipe flanges.Pipe Fittings,accessories used to connect two pipes. The connection provides a firm bound to the pipe which ensures mechanical and structural strength to hold the equipment. It also ensures the free flow of liquid in the process.Most Commonly used pipe fittings are Elbow, Tee, Reducer, Bends, Cap and stub ends.

 

The complex chemical and physical properties of the various grades of API 5L welded pipe allow for a broad range of service usage.It is widely used for transmitting oil, natural gas,water and other liquids.API 5L X Grades 42 through 70 are utilized for the water and petroleum industry to transport liquids or as platforms on offshore rigs.

 

As a professional manufacturers of butt weld pipe fittings and pipe flanges,we have to meet specifications and requirements of many organizations to assure quality, compatibility and performance of their products including American Society for Testing and Materials (ASTM), American Society of Mechanical Engineers (ASME), International Organization for Standardization (ISO) and so on.Take API 5L welded pipeline Grades B (X42, X52, X60, X65 X70 and X80) for example,the commonly used pipe fittings are listed as follows:
