Time:12/13/2016 6:45:42 PM

ASIN Steel Flanges are parts to connect pipes, and there is a hole in the middle, so the bolt can be used to joint two flanges. Generally, we use gaskets to seal the chink between the two flanges.American standard steel flanges can be made by casting, threaded or welded. Besides, ASIN steel flanges’ connection is detachable. We usually make two pipes, fittings or equipment mount on the flange separately, then using gasket seals the chink  between two flanges and using bolt fastens flanges.


ASIN steel flanges’ connection is an important way for pipeline construction. New standard flanges are easy to use, and able to withstand greater pressure. Of course, there are some pipe and fittings has added flanges already, it is also belongs to the flange.
