ZQD series reducer

People who often come into contact with the ZQD series reducer know that it is mainly an anti-corrosion equipment. When the manufacturer produces the ZQD series reducer, a welding step is carried out. Welding is a crucial step for the entire production of the ZQD series reducer, so the manufacturer attaches great importance to this step. Welding may directly affect the normal use of the ZQD series reducer. Next, let's learn about the testing standards for welding:

1.When welding ZQD series reducers, it is required that all welds undergo non-destructive testing using endoscopes and X-rays to meet certain standards before welding can begin. During this process, it is important to ensure that they are firm and level, and comply with relevant usage standards.

2. All welding points of ZQD series reducers must be properly recorded. This operation must be carried out by professional operators.
3.After welding the ZQD series reducer, a pressure test and passivation treatment should be carried out on the pressure vessel and all pipelines of the equipment.
4.When welding the outer wall surface of the ZQD series reducer, it is necessary to cover the position of the auxiliary alarm on the surface of the equipment to avoid damage to the equipment during the welding process.
The above introduction is about the relevant standards for the use and testing of welding in the production process of ZQD series reducers. Therefore, when purchasing ZQD series reducer equipment, it is necessary to find a professional manufacturer to ensure quality in the later stage.
