Abstract
Proposed by the present invention is a kind of method that stainless steel manifold configuration prevents welding deformation.Including following processing steps: (1), by the stainless steel assembled supervisor and manifold configuration, carrying out watertight closure at the pipeline both ends of supervisor, be respectively kept with water inlet pipe and outlet pipe in closure；(2), after watertight closure installs, water circulating pump is connect with the water inlet pipe blocked；(3), after the completion of connecting, one end that stainless steel is responsible for not connected water pump is lifted, with ground at 30~45 ° of inclination angles；(4), after reaching required angle, supervisor is filled the water, there are flowing out to the other end, and without stopping water filling, at this moment, this being brought out water pipe and is connect with water pump, while controlling water outlet in the case where bubble, is not allow for water outflow；(5), stainless steel tube is then placed into level, prepares welding, 15s supplies water in advance before welding, 0.5~2L/min of water flow.The present invention improves the quality of product and using safe using welding region thermal deformation is reduced.It is suitable as the method application for preventing welding deformation.
Description
Technical field
The present invention relates to the welding deformations of welding field, more particularly to stainless steel manifold configuration welding deformation.
Background technique
Stainless steel pipes are got a lot of applications in China's nuclear industry, pressure vessel industry.According to requirements, in main body
On pipeline, it is also necessary to branch pipe be installed by the way of welding.These branch pipe enormous amounts, and welding capacity is huge.Welding deformation control
Difficulty processed is very big, and is not easy to guarantee.For the installation and use of follow-up equipment, the hidden danger of technology and safety is brought.
Summary of the invention
In order to solve the deformation controlling problem of stainless steel supervisor and stainless steel branch pipe welding, the invention proposes one kind
The method that stainless steel manifold configuration prevents welding deformation.This method is responsible in welding process by stainless steel branch pipe and stainless steel,
Using to by the way of the through-flow water of stainless steel main pipe, cooling processing is carried out to welding region, reduces welding region due to heated
Caused by thermal deformation, solve the technical issues of stainless steel supervisor is with stainless steel branch pipe welding Deformation control.
The technical proposal for solving the technical problem of the invention is:
In stainless steel branch pipe and stainless steel supervisor's welding process, using to by the way of the through-flow water of stainless steel main pipe, butt welding
It connects region and carries out cooling processing, reduce welding region thermal deformation as caused by heated, including following processing steps:
(1), by the stainless steel assembled supervisor and manifold configuration, watertight closure is carried out at the pipeline both ends of supervisor, is divided in closure
There are water inlet pipes and outlet pipe；
(2), after watertight closure installs, water circulating pump is connect with the water inlet pipe blocked；
(3), after the completion of connecting, one end that stainless steel is responsible for not connected water pump is lifted, with ground at 30~45 ° of inclination angles；
(4), after reaching required angle, supervisor is filled the water, there are flowing out to the other end, and without stopping in the case where bubble
It only fills the water, at this moment, this is brought out into water pipe and is connect with water pump, while controlling water outlet, be not allow for water outflow；
(5), stainless steel tube is then placed into level, prepares welding, 15s supplies water in advance before welding, 0.5~2L/min of water flow.
Good effect is responsible for since the present invention is using in stainless steel branch pipe and stainless steel supervisor's welding process using to stainless steel
The mode of internal through-flow water, carries out cooling processing to welding region, reduces welding region to the greatest extent and is caused due to heated
Thermal deformation, the method achieve stainless steel supervisor and the deformation problem difficult to control of branch pipe welding, ensure that stainless steel supervisor with
The structure size of branch pipe improves the quality of product and using safe.It is suitable for preventing from welding as a kind of stainless steel manifold configuration
The method application of deformation.
Specific embodiment
The 316L stainless steel tube of Φ 250mm X30mm is as supervisor, the specific embodiment of branch pipe welded directly to the run pipe, implementation step
It is as follows:
1, by the 316L stainless steel assembled supervisor and manifold configuration, in the pipeline both ends of supervisor progress watertight closure, closure
It is respectively kept with water inlet pipe and outlet pipe；
2, after watertight closure installs, water circulating pump is connect with the water inlet pipe blocked；
3, after the completion of connecting, one end that stainless steel is responsible for not connected water pump is lifted, with ground at 35 ° of inclination angles；
4, after reaching required angle, supervisor is filled the water, there are flowing out to the other end, and without stopping in the case where bubble
Water filling, at this moment, brings out water pipe for this and connect with water pump, while controlling a water outlet, is not allow for water outflow；
5, stainless steel tube is then placed into level, prepares welding, 15s supplies water in advance before welding, water flow 1.5L/min.
6, then start to weld, welding process is continuous, and postwelding measures branch pipe and supervisor's positional relationship variation, does not have through detection
Overproof variation.
