    1. Groove Steel FlangeGroove steel flange is a specially processed flange with grooves on the surface or inner circle of the flange. It can be specially made to suit your requirement according to the given design drawing.

Pipe Flange

Pipe flange, also known as flange plate, is a component located at the pipe end that can get tightly linked together by bolts through the holes. A pad in bdheen can avoid leakage of liquid and gas. This accessory is made via die forging followed by machinery modeling. We offer flanges with a production range of 1/2″ to 48″ (DN15~DN1200) and two kinds of sealing surface for option that are raised face (R.F) and flat face (F.F).

Classification
1. Based on different connecting methods, the product can be divided into seven groups, i.e. weld neck flange, plate flange, blind flange, socket weld flange, slip on flange, threaded flange and groove steel flange.
2. According to different materials used, there are carbon steel flange, alloy steel flange and stainless steel flange.
