Abstract
The present invention relates to a kind of technical field of heat exchange equipment, more specifically to a kind of processing technology taken over flange.In heat transmission equipment, for leaking phenomena such as is particularly important, and such equipment often ensures by welding and assembly technology, and reliable welding and assembly technology not only can guarantee the quality of product, but also can improve production efficiency.A kind of processing technology taken over flange, includes the following steps：Stock：Preparation take over, flange；Scribing line：It takes over and crosses by drawing size；Blanking：It takes over by wire cutting blanking, takes over and assembled by welding procedure sheet bevel：Take over, flange assembles as required, control flange and the perpendicularity deviation taken over, and ensure each fitted position；Welding：By welding procedure sheet welding, weldering label is made on trimming surface；Non-destructive testing：Flaw detection label is made by B class weld seam non-destructive testings.This technique is advanced, ensure that the welding quality of each section, ensure that the quality of product, can greatly increase production efficiency.
Description
Technical field
The present invention relates to a kind of technical field of heat exchange equipment, more specifically to a kind of processing work taken over flange
Skill.
Background technology
In heat exchanger and related efficient and compact heat transmission equipment, since such equipment coefficient of heat transfer is high, the pressure loss

Pay attention to.But such equipment is in the application of chemical, for leaking phenomena such as is particularly important, and such equipment is often leaned on
Welding and assembly technology ensure that reliable welding and assembly technology not only can guarantee the quality of product, but also can improve production effect
Rate.
Invention content
The purpose of the present invention provides a kind of quality ensureing product and can improve production aiming at the deficiency of the prior art
The processing technology of efficiency.
A kind of processing technology taken over flange, includes the following steps：
1) it stocks up：Preparation take over, flange；
2) it crosses：It takes over and crosses by drawing size；
3) blanking：It takes over by wire cutting blanking, takes over by welding procedure sheet bevel；
4) it assembles：Take over, flange assembles as required, control flange and the perpendicularity deviation taken over, deviation must not surpass
Flange outer diameter 1% is crossed, and is not more than 3mm, and ensures each fitted position；
5) it welds：By welding procedure sheet welding, weldering label is made on trimming surface；
6) non-destructive testing：Flaw detection label is made by B class weld seam non-destructive testings.
Reach following advantageous effect：This technique is advanced, ensure that the welding quality of each section, ensure that the quality of product,
Production efficiency can be greatly increased.
Specific implementation mode
The specific implementation mode of the present invention is described in detail below.
The present invention is a kind of processing technology taken over flange.
The processing technology taken over flange described in the present embodiment, includes the following steps：
1) it stocks up：Preparation take over, flange；
2) it crosses：It takes over and crosses by drawing size；
3) blanking：It takes over by wire cutting blanking, takes over by welding procedure sheet bevel；
4) it assembles：Take over, flange assembles as required, control flange and the perpendicularity deviation taken over, deviation must not surpass
Flange outer diameter 1% is crossed, and is not more than 3mm, and ensures each fitted position；
5) it welds：By welding procedure sheet welding, weldering label is made on trimming surface；
6) non-destructive testing：Flaw detection label is made by B class weld seam non-destructive testings.
It is above the preferred embodiment of the present invention, protection scope of the present invention is not limited, for people in the art
The deformation and improvement that member's mentality of designing according to the present invention is made, all should be considered as within protection scope of the present invention.
