Fitting the classification of information, introduces below is provided by wenzhou pipe fittings.
Wenzhou fittings according to the classification of USES
1, used for tube connected to each other fittings are: flange, articulated, pipe hoop, card sets and throat hoop, etc
2, change the direction of the pipe fitting: elbow
3, change the pipe diameter of the tube: variable diameter (reducer), reducing elbow
4, add piping branch pipe fittings: tee, four-way
5, used for pipe line seal: gasket, ribbons, cotton and ramie thread woven, blind flange plate, tube plugging
6, used for pipe fixed tube: snap ring, towing hook, rings, bracket, bracket, pipe clamp, etc
Wenzhou pipe connection and special-shaped tube, is connection of the pipe installation accessories, used in [1] variable diameter, which leads to the branch, change for piping, pipe end block etc. Pipe connections are threaded connection, socket connection and electric melting welding this several.
BUTT WELDING pipe fittings (BUTT WELDING FITTING/BW) -- -- -- -- -- -- -- -- refers to the pipe and pipe fittings on the WELDING groove BUTT weld pipe connected.
SOCKET WELDING pipe fittings (SOCKET WELDING FITTING/SW) -- -- -- -- -- -- -- -- -- refers to the inserted within the SOCKET pipe fittings fillet WELDING way of connecting pipe fittings.
THREADED pipe fittings (THREADED FITTING/THD) -- -- -- -- -- -- -- refers to the thread with a thread within the pipe and pipe fittings with screwing way connecting pipe fittings.
Mixed connection type pipe fittings -- -- -- -- -- - refers to a fitting end for a different connection types of pipe fittings, such as one end of the pipe butt welding type, and the other end of the thread type.
NOMINAL SIZE (NOMINAL PIPE SIZE/NPS) -- -- -- -- -- -- -- -- the PIPE inside diameter, in the name of the now standardization, seriation, generalization of a numerical after roundness, representative of the specifications of the pipes. Usually domestic DN as the nominal size of the code.
Structure size -- -- -- -- -- -- -- -- refers to the part of the center of the pipe to the face (such as elbow, tee, four-way), face to face, such as reducing pipe size.
Above is the classification of wenzhou fitting information.
