Introduction: The quality of flanged couplings on the market is really diverse, which also leads to high and low prices; As the saying goes, "You get what you pay for." It's true. Flange coupling material and processing are excelsior, long service life more durable; And inferior products, the use of material is relatively poor, rough processing, leading to short service life. What effect does material and quality have on price? Material and quality of flange coupling: Flange coupling material can be divided into: cast steel, forged steel, aluminum alloy and other materials, generally use cast steel more; The different materials directly affect the price. Quality impact: there are non-standard processing, also provide models of national standard processing. Among them, processing precision and quality affect the price. To sum up: The manufacturer can match the flange coupling according to the working condition of the user. At the same time, also undertake a variety of non - standard model coupling. Users are welcome to inquire, to provide you with durable coupling.
