With the implementation of China's reform and opening up policy, the rapid growth of the national economy to get, in many cases, stainless steel pipe more advantages, especially in wall thickness of only 0.6 ~ 1.2mm thin-walled stainless steel pipe in high-quality drinking water systems, hot water systems and the safety and health of the water supply system in the first place, a safe, reliable, environmental health, affordable and other characteristics, has been proven to be the best domestic and international engineering, the new, energy-efficient and environmentally friendly pipe of the water supply system overall performance First, because it has more advantages to other pipe irreplaceable, project application will be more and more use will become increasingly popular, so today small to tell you how to choose the right stainless steel pipe, hope can give you some help.
First, before you need to take into account the selection of stainless steel pipe stainless steel pipe use and the use of the environment.
Second, in the selection of pipe material must determine compliance. In 304, for example:
1. Available acidic reagent test, 30 seconds after the material does not change color 304, 201 become black;
2. Carefully look at "304," the words stenciled pipe surface material is hit, and to obtain a certificate as a manufacturer of quality certificate;
3. From the price analysis, even if the 304 stainless steel tube 301 is lower than the market price of the material should be carefully distinguished general, there may be other material posing;
4. When buying large quantities can be extracted samples were sent to the authority of the State Testing Center laboratory testing components.
Third, watch the outer surface and the inner wall of the color is bright and smooth, the thickness is uniform or rough phenomenon.
General Pipe this basic need to check, and the use of cold-drawn or hot-rolled seamless steel pipe is produced, the operation in the production process prone to uneven thickness improper tube surface cracks and other phenomena, and the surface roughness is generally seamless not be polished, if no special requirements for appearance does not affect use.
Fourth, the purchase should choose Quality and Technical Supervision assessed outstanding products.
Fifth, we must try to choose the inner tube and re-rolling skin, pitting, and rolling green line and so small, especially if the surface is smooth inside to check the time of purchase.
The above is an optional stainless steel pipe some tips to select high-quality stainless steel tube is not only safe, reliable, health and environmental benefits, but also has an affordable, can effectively reduce the cost of production of the factory, increase economic efficiency. The company's products have been proven to be one of domestic and foreign construction of water supply system the best overall performance, the new, energy-saving and environment-friendly pipe, but also a very competitive water pipe, is bound to improve water quality, improve people's living standards play an unparalleled role.
