How to choose a good Tinned Copper Braided Sleeve

1. Take the material as an example: when selecting steel pipes, be sure to make sure that the material meets the standard.

2. From the price analysis, if the material of the Tinned Copper braided sleeve is even lower than the general price of the material on the market, it must be carefully identified, it is likely to be faked by other materials.
3. Identify whether the steel stamp material can be printed on the surface of the pipe, and ask for the manufacturer's quality certificate as a proof.
4. It can be detected by acid reagent, and the material will not change color after 30 seconds, but will turn black.
5. For mass purchases, samples can be taken and sent to the national authoritative testing center for component testing.
6. Inner heavy skin, pitting and rolling green lines often appear in the rolled pipe. Under normal circumstances, these can not be avoided, and basically do not affect the use, but you must choose as few as possible when purchasing. Yes, especially check the inner surface layer.
7. When purchasing, you should choose excellent products that have been evaluated by the Bureau of Quality and Technical Supervision. Long-term use testimony and good reputation among customers are the most immediate and effective way to purchase.
8. Check whether the color of the outer layer and the inner wall of the tube is bright and smooth, whether the thickness is uniform or not smooth. Generally, welded pipes basically do not need to be inspected, while seamless steel pipes with Cable Sleeve are manufactured by cold drawing or hot rolling. Improper operation in the manufacturing process is likely to cause uneven thickness and cracks in the pipe, and the surface layer is not smooth. Smooth generally means that the seamless steel pipe has not been polished and polished. If there is no special requirement for the external shape, it will not affect the use.
9. The main purpose and conditions of use of the tinned copper braided casing should be fully considered before selecting the Cable Sleeve seamless steel pipe. Such as: welded pipes are generally used for decoration, seamless steel pipes are generally used for fluid transportation, sanitary Tinned Copper Braided Sleeve are used for medical treatment or kitchens, and thick-walled pipes are used for pressure. Generally, a series of materials can be used indoors, and other materials should be used outdoors,and the above materials are generally used in acid-alkaline places or coastal areas.
