The special properties of stainless steel tube are:

1. Excellent corrosion resistance: As the surface of stainless steel will form a thin layer of protective film, although the protective film is about 3 脳 10-6 mm, but very tough, even if damaged, as long as there is oxygen Can be immediately regenerated to prevent rust, as long as the characteristics of stainless steel and the correct use of the words, in the water pipe or 100 鈩 hot water and other less corrosive conditions, Stainless Steel Pipe and Tube almost do not have to worry about rust, do not worry in galvanized steel pipe Resulting in a common "rust protrusions" caused by the smaller inner diameter or resistance to increase the phenomenon, can not get blocked water flow.

2. Health and reliable and do not have to worry about red water, green water and other phenomena.

3. Stainless Steel Pipe and Tube Due to the lighter, easy handling and construction and reduce costs.

Stainless steel pipe due to corrosion resistance and mechanical properties of superior, only about one-third of the thickness of galvanized steel pipe can be. So the weight of the pipe greatly lighter, the cost will be reduced, so that handling more easily, the installation more convenient.

4. Impact resistance

5. Distortion: In the construction site, due to the construction site, space and construction tools, Stainless Steel Pipe and Tube construction workers often use the plastic pipe and not according to the construction specifications forcibly construction, so it is necessary to consider the pipe and pipe joints twist factors.

In the selection of stainless steel pipe before taking into account the use of stainless steel and the use of the environment. Such as: decoration with the general use of welded pipe, fluid delivery generally use seamless tube, medical or kitchen to use sanitary stainless steel pipe, pressure using thick-walled tube; general indoor 200 series material can be used outside the use of 304 and other materials, and In the alkaline or coastal areas generally use more than 316 materials.

Second, Stainless Steel Pipe and Tube in the selection of stainless steel pipe must be determined when the material standards. Take 304 material as an example:

1. From the price analysis, if the 304 material stainless steel pipe or even lower than the market price of 301 material to be carefully identified, it is likely that other materials posing;

2. Recognize whether the surface of the steel seal material "304" words, and to obtain the manufacturer quality certificate as a certificate;

3. Available acid reagent test, 30 seconds after the material does not change color 304, 201 black;

4. Large quantities of purchased samples can be sent to the national authority of the test center for component testing.

Third, watch the outer surface and the wall of the tube is bright and smooth, the thickness is uniform or rough phenomenon. General welded pipe this basic do not have to check, and seamless steel pipe is cold drawn or hot-rolled way of production, improper operation in the production process prone to uneven thickness, the surface cracks and other phenomena, and the surface roughness is generally seamless No polishing treatment, Stainless Steel Pipe and Tube if the appearance of no special requirements do not affect the use.

Fourth, the purchase should be selected by the Quality and Technical Supervision assessed the outstanding products. In the customer there is a long time to use witness and good word of mouth is the most direct and effective way to buy.

5, rolling pipe often appear within the heavy skin, pitting, and rolling green line, under normal circumstances these can not be avoided, but also does not affect the use of the general, but must choose to buy as little as possible, in particular, check The inner surface.
