Plate Steel Pipe Flange

A plate steel pipe flangeis suitable to be used in pipe connections whose nominal pressure is no morethan 2.5 MPa. It is extensively used in food making, pharmacy, oil, chemical,mechanical engineering, sewage treatment, electricity, ship building, papermaking and metallurgical industries.

Different types of facesfor the plate steel pipe flange include flat face, concave-convex face and tongue groove face. Flat faceflange type is the most used, even on conditions that low pressure unpurifiedcompressed air or low pressure recycling water are flowing. In addition, thereare many advantages using a plate steel pipe flange. It saves space and reducesweight with no leak connections. It is compact because its sealing component diameterhas been reduced.

Plate steel pipe flange is mold forged first and thenmachine finished. The plate steel pipe flange outdiameter ranges from 3/8" to 80" and nominaldiameter ranges from DN10 to DN2000. PN grade is abar indicator of the pressure that pipe can support with water at 20oC. The pressure grades available according toEuropean standards are PN 2.5, PN 6, PN 10, PN 16, PN25, PN 40, PN 63 and PN 100.
