Product Description
Steel Flanges Manufacturer Exporter - BS4504 DIN BSPT Screwed Thread Flanges - Jinan Hyupshin Flanges Co., Ltd
We supply steel flanges type Threaded Flange BSPT, Screwed flange BSPT, flange facing usually for Raised Face (RF).
Threaded flanges (Screwed Flange) BSPT size DN15-DN150 for EN1092-1, BS4504 and DIN norm and pressure for PN6 and PN16.
Threaded flanges (Screwed Flange) BSPT steel material carbon steel by forging for P250GH P265GH S235JRG2 C22.8 for European flanges norms.
Threaded flanges BSPT also name screwed flange BSPT is for BS4504 or DIN or EN1092-1 flanges screwed norms.
What is threaded (screwed) BSPT flange?
BSPT flange is BS4504 screwed flange, BSPT means British Standard Pipe Thread so BSPT flange is fit for BSPT screwed pipe, BS4504 code 113 DIN2565 DIN2566 and EN1092-1 type 13 are all BSPT screw flange.
BSPT (British Standard Pipe Thread) is similar to NPT except there are important differences. The angle across the flanks of threads (if you sliced the fitting in half long-ways and measured the angle from root to crest to root) is 55 degrees instead of 60 degrees as it is for NPT. Another important difference is that for many BSPT pipe sizes the thread pitch is different than NPT. Thus an NPT male will sometimes fit into a BSPT fitting or vice versa but they will not seal. This is a popular fitting in China and Japan but is very rarely used in North America unless the equipment to which it is attached was imported. Thread sealant is needed to seal the male and female fitting together. Ralston Instruments has adapters to both male BSPT adapters and female BSPT adapters.
what different between BSPT, NPT?
NPT Connections
NPT (National Pipe Thread) seals are the most popular type of seal for pressure calibration systems in the U.S. and Canada. NPT male adapters have a taper thread that wedges into the female NPT adapter. They seal due to the "out of roundness principle" which means that the male stretches the female fitting until there is so much force that the connection can hold pressure. One of the challenges with this design is that if you connect stainless steel to stainless steel then over-tightening or poor lubrication can cause gauling and damage to the threads. Thread sealant is needed to seal but only 2 turns of thread sealant is required. Any more than that and the seal can leak around the thread sealant. Ralston Instruments has a wide variety of male NPT adapters , male Quick-disconnect NPT adapters, male NPT calibrator adapters, female NPT adapters, female NPT gauge adapters and female Quick-disconnect NPT gauge adapters.
