Stainless Steel Hose Companies to Briefly Introduce Some Products to Avoid Choosing Inferior Products
The stainless steel bellows hose company will briefly introduce how to choose a few products to use a good life and how to avoid choosing inferior products
- The use of the product is of course the first to bear the brunt. Different materials have different materials, generally 304 stainless steel, large-diameter metal hose materials: various types of pipeline compensators, should be based on design requirements or medium corrosion, medium temperature Material selection, generally 321, 304, 316, 316L and other stainless steel materials.
- Pressure is also a consideration for users. The pressure design of the product is mainly the thickness of the bellows. This is what the industry is unwilling to do for customers. The internal structure design can reduce the cost of the product.
The pressure range for industrial and plumbing is also different. Generally, 0.1-2.5MPA is used. Special applications can be customized and can reach 30Mpa.
- Material identification, the simple method in the industry is to use magnets to attract, generally attracted to iron, carbon steel other methods are: color identification, identification with magnetite, copper sulfate identification, for special properties of steel We need to adopt the following three methods for identification. , Identification of grinding flower, identification of annealing method, identification of chemical qualitative method The simple and direct method is to use stainless steel potion
- Welder of product assembly: This is directly related to the company’s professional equipment and professionals
Welding material: electrode wire used; 2. Total number of welded joints: total number of welded joints of the pipeline (including fillet welds and flange fillet welds); 3. Unevenness of welded joints: refers to the residual height and small difference of welded joints Poor; 4. Reinforcement layer of the weld: it is the residual height of the weld, and the width is the width of the weld; 5. Undercut: the depth is deep, 6. The appearance quality inspection conclusion: qualified, unqualified: 7. welder welder stamp: A total of several welders participated in the pipeline.
