How does the mining pipe fittings work normally? What are the technical requirements for the subsequent pipe fittings?
The company is a company specializing in providing products and services such as plastic-coated composite steel pipes, internal and external coated malleable steel pipe fittings, etc. Do you know what technical requirements for the subsequent pipe fittings? This article will give you a detailed introduction to the content of this aspect. Let's take a look at "how the mining pipe fittings work normally and what are the technical requirements for the pipe fittings in the future?"
Mining pipe fittings may have problems such as water seepage during long-term use. To ensure the quality of mining pipe fittings, the mining pipe fittings should be maintained during use, and measures should be taken to improve the mine pipe fittings for water seepage problems.
Mine pipe fittings produce water seepage, first release the pressure, loosen the bolts, and check whether the rubber ring is squeezed and deformed. If the rubber ring is squeezed, replace the rubber ring directly.
If the riser has been fixed and the rubber ring cannot be replaced, put rubber in the steel card shell to increase the compression.
If there is no problem with the rubber ring, check whether the paint on the sealing surface of the mining pipe fittings has fallen off in a large area. If it falls off, scrape the paint on the entire sealing surface or replace the pipe fittings. Pay attention to the size and matching of the rubber ring. These measures can better deal with mining pipe fittings.
Since the pipe fittings are generally connected by welding, for the convenience of welding, the steel grades of the sanitary pipe fittings and the pipes to be connected are the same; that is, all pipe fittings must be surface-treated, and the iron oxide scale on the inner and outer surfaces is shot peened. Spray it off, and then apply anti-corrosion paint. In order to facilitate transportation and prevent rust and oxidation, this work must be done. In order to improve the welding quality, the ends are all beveled, leaving a certain angle and with a certain edge. This requirement is also relatively strict, and the thickness of the edge, the angle size and the deviation range are specified. The surface quality and mechanical properties of grooves are basically the same as those of pipes.
