Description

Flat welding flange is a kind of excellent pipeline construction component, which is very common in pipeline construction, and there are many kinds of flange, among which the flat welding flange is relatively famous.

Flat welding flange refers to the flange with neck and pipe transition. Welding flange is not easy to deform, so it has corresponding rigidity and elasticity requirements and reasonable welding thinning transition. It is usually used to connect pipelines and valves with PN more than 2.5MPa. Flat welding flange is also used to transport flammable and explosive media.

Specification

Standard:DIN,ANSI,ASTM,JIS,GB

Size:1/2' ~ 6'

Usage:Steel pipe,Oil Gas Water

Characteristic

The flat welding flange is suitable for the connection of steel pipe with nominal pressure less than 2.5MPa. The sealing surface of Chongqing flange can be of lubricating type. There are concave convex type and tenon groove type, lubricating flat welding flange is widely used, and the medium condition is relatively loose, it can be used.

The raw material of flange is the steel plate produced by regular enterprises, and the raw material is relatively regular. Generally, there are many small apertures, simple processing, flat tread and low cost. It is low cost to train embryos with waste pin.

The flat welding flange is easy to obtain materials, easy to manufacture, low cost and widely used. But the rigidity is poor. Therefore, the supply and demand of chemical process piping system and height which are easy to burn, easy to explode and require high vacuum degree, and the types of sealing surface include plane and protruding surface.

Flange is generally cut with steel plate heating winding, raw material is also very good. The welding interface can not be seen after processing, but the density of flange forged with high pressure piping is very high, and the processing is very troublesome. Only one interface is welded in the middle, and the quality is very good.
