It is good.
3rd, it can flexibly consider whether to need to add sealing fillet weld according to the occasion difference of application.Do not using sealing
In the case of fillet weld, maintenance can be easily dismantled.
4th, site operation is flexibly simple, compared with after the completion of welding using professional equipment polishing inner wall, does not need to even more
Professional equipment saves installation cost.Every one of connecting sewing of pipeline can be accomplished to estimate simultaneously, and convenient for checking, construction quality is held
Easily ensure.
In conclusion the design structure is simple, processing cost is low, and scene is easily installed realization, while safe and reliable.In work
The consistent favorable comment of engineering procurement, unit in charge of construction and owner is obtained in journey practice.
