How to deal with the leak problem of flanges? Here we’d show you the sealing treatment method by case analysis.
Here are eleven major technical characteristics of fully welded ball valve if you want to know more about fully welded ball valve. 1. The body structure of fully welded ball valve is welded. Therefore, there is no external leakage phenomenon happening.
A stainless steel pipe reducer (with a larger and a smaller head) is applied to pipeline where size diameter needs changing. Forming process methods used for reducers commonly contains necking pressing, expanding pressing or a combine of these methods.
Flanges provide the necessary connections to link pipelines. Faces are the mating surface of a flange. Flange faces have to be smooth enough to ensure a tight, leak-free seal for bolted flanges.
Galvanized steel Pipe is surface finished pipe that has been coated with a thin layer of zinc to help prevent corrosion. Zinc, a natural, healthy, and abundant element was first used in construction in 79 AD.
1. The main reason for this is the expensive maintenance fee, so the operating managers do not maintain ball valves. Or lacking of scientific management and preventive maintenance, the valve will have a failure in advance.
1. Before installation, check whether pneumatic butterfly valve has missing parts or not. Ensure that each part model is correct. And there are no other objects within valve and it is clog-free in solenoid valve and the muffler.
1. The disc of safety valve doesn’t return back after the discharge. This is mainly because of the bent stem or the disc is out of position, so you should assemble it again.
First of all, before installing safety valve, be sure to test the seal performance. If there is relief valve leakage or breakage of air cushion, it is needed to change immediately. Then, we can get the best use of it.
In China, multi-way valves are still in the process of research and development. So, compared with those valves which have been developed for a long period, multi-way valves will meet more troubles in normal use.
