Hydraulic presses for forging ring blanks

The first forging operation when manufacturing seamless rings is forging ring blanks. Ring rolling lines turn these into the precursors for bearing shells, crown gears, flanges, turbine disks for jet engines and various highly stressed structural elements. Hydraulic presses are particularly well ... Read More

168 Forging mesh: What are the principles and methods of forging die renovation?

In forging die work, if the main parts of forging die are found to be too badly damaged to be repaired randomly, the forging die should be removed and repaired by the die maintainer. 1.The principles of renovation are as follows: (1) Die parts exchange or part update, must meet the forging die de...

RAISED FACE FLANGE (RF)

A raised face flange (RF) is easy to recognize as the gasket surface area is positioned above the bolting line of the flange. A raised face flange is compatible with a wide range of flange gaskets, ranging from flat to semi-metallic and metallic types (as, for example, jacketed gaskets and spiral... Read More

flange designs

Commonly used flange designs have a soft gasket squeezed between harder flange surfaces to form a leak-free seal. The various gasket materials are rubbers, elastomers (springy polymers), soft polymers covering a springy metal (e.g., PTFE covered stainless steel), and soft metal (copper or aluminu... Read More

Flange seals provide the front-face static sealing function within flange connections.

Flange seals provide the front-face static sealing function within flange connections. There are two major design principles available, either for internal or external pressure. Various designs in a broad range of compounds provide individual features. flange seals offer enhanced sealing performa... Read More

Knowledge of machining forged circle

Forging circle belongs to a kind of forgings, in fact, to put it simply, it is the forging of round steel. Forged circles are obviously different from other steel in industry, and forged circles can be divided into three categories, but many people do not have a special understanding of forged ci...
