In the current market, a variety of valve products are quite rich, so various types of valve accessories are also emerging. Valve fittings also include a wide range of fasteners. When selecting fasteners, users can conduct comprehensive analysis and consideration through the following five aspects to determine the grades, varieties, specifications and material standards of fasteners. The following five aspects include:
1. The mechanical properties of the fastener materials of the valve fittings should meet the requirements for use, especially the strength should meet the relevant standards;
2. The actual application environment and working conditions of the fasteners of the valve fittings should meet the requirements for the corrosion resistance of the materials.
3, the operating temperature of the fasteners of the on-site valve parts on the heat resistance of the material, including high temperature strength and oxidation resistance.
4. At the same time, we must also consider the requirements for the processing properties of fastener materials in the production process.
5, in addition to other aspects also need to be considered, such as the weight of the valve parts, the price, procurement requirements, etc. should be considered.http://www.pump-casting.com/
