Forging flange
  • PRODUCT NAME:

    Forging flange

  • DESCRIPTION:
    The hardness of the forged flange is generally only more than 30 degrees when the material is hardened badly. ..

DESCRIPTION

The main purposes of forged flanges are:

1, connect the pipeline and maintain the sealing performance of the pipeline.

2. Convenient for the replacement of a certain section of pipeline; Folding production process is mainly divided into forging, casting, cutting, rolling these four kinds. Cast flange and forged flange folded cast flange, the shape and size of the blank is accurate, the amount of processing is small, low cost, but there are casting defects (pores, cracks, inclusions); casting internal structure streamline poor (if cutting pieces, streamline poor); free forging productivity is low, machining margin is large, but the tool is simple, universal Because of its large nature, it is widely used for forging single piece and small batch forgings with simpler shapes.

Forged flange connection is to fasten two pipes, pipe fittings or equipment on a flange plate, two flanges between, plus flange pad, fastened together with bolts, completed the connection. Some pipe fittings and equipment have their own flange, and also belong to flange connection.

The hardness of the forged flange is generally only more than 30 degrees when the material is hardened badly. Normally, the forged flange is often treated by water quenching. The chromium content is 0.1%-0.5% (forged flange does not contain chromium in general), the carbon content is less than 1.0% and the forged flange is forged by high temperature forging. Some forged flange surface hardness (hrc) is acceptable though In order to achieve more than 56 (hardened layer is only about 15), the hardness of the center of forged flange is generally only more than 30 degrees due to poor hardenability of the material. Under normal circumstances, the forged flange is often treated by water quenching.
