Socket Weld Flanges (SW Flanges) are similar to slip-on flanges in outline, but the bore is counter-bored to accept pipe. The diameter of the remaining bore is the same as the inside diameter of the pipe. The positive of this is that is creates a smooth bore with the proper welding and grinding. The negative of this type of flange is that it can be more expensive than a slip-on due to more intricate machining, and they can be less readily available than slip-ons due to the fact that the bottom half of the inside diameter must be made to the same schedule as the pipe that is being used. (you must specify the schedule needed) These socket weld flanges were initially developed for use on smaller sizes of pipe at higher pressure ratings.
Socket Weld flanges are typically provided with a raised face, flat face, or RTJ facing. When a raised face is necessary for socket weld pipe flanges, the standard height is 1/16 inch for socket weld pipe flanges less than 400#. For socket weld pipe flanges of 400# and up, the standard socket weld pipe flange raised face height is 1/4 inch
Example:
British and French pipe flange standards, two countries each have two pipe flange standards, to sum up, the international pipe flange standard can be summarized as two different, and not interchangeable pipe flange system: a European pipe flange system represented by Germany; Another is the American pipe flange system represented by the United States. Ios7005-1 is a standard promulgated by the International Organization for Standardization in 1992, the standard is actually the United States and Germany two series of pipe flanges merged into the pipe flange standard. The pipe flange connection sizes of the two systems are different and cannot be matched with each other. The pipe flanges of the two systems are most suitable to be distinguished by pressure grade, that is, The European system is 0.25, 0.6, 1.0, 1.6, 2.5, 4.0, 6.3, 10.0, 16.0, 25.0, 32.0, 40.0MPa. The American system is 1.0, 2.0, 5.0, 11.0, 15.0, 26.0, 42.0MPa.
1. Current status of pipe flange standards in China
Common standards for pipe flanges used in China's chemical and petrochemical industries 1. British pipe (internationally common piping series) GB 9112-9125, SH 3406
2, metric pipe (commonly used domestic steel pipe outer diameter size series) HGJ44 ~ 76, JB/T74 ~ 90 DIN connection size and JB standard is different
