Some proposals for stainless steel pipe procurement 
1. Various performance indicators (mechanical properties, wall thickness, surface): in fact, as a seller, it is good enough to know what is the material and surface of goods. It is not realistic for them to know all various performance indicators. So, I suggest buyers pay much attention to the following several aspects when buying goods: whether the goods surface has rusty spots or not, whether it is smooth and whether the wall thickness is even or not. Maybe it is the most direct method when choosing the products by looking the surface, but it is not the important way.
2. Material: for example, 304 material is a common material in the market. Its old standard is 0cr18ni9, while the new standard is called 06 cr19ni10. The old standard of phosphorus content is below 0.035, and the new standard is below 0.045. The old standard of chromium content is more than 17, but the new standard is over 18. Now for most steel manufacturers, they have made the adjustment in phosphorus content, but not including chromium content. So it is impossible that the customers can buy those pipes whose chromium content is over 18 in the market.
3. It is the market distribution members and the loading personnel that know the market situation very well, so you can seek the information from them.
4. At last, you can find the new information through the network or go to the steel mills in person. In the domestic situation, it is not common for steel manufacturers who also do drawn tube business. Moreover, those factories which can invest drawn tubes may not have the power to build steel mills. So, generally speaking, steel pipes with good quality are always manufactured by the steel mills. What’s more, the price is just the same with that of goods imported by dealers
