This customer first sent mail to us and contacted me on Whatsapp immediately after that. From him, I got the information that this list is for a project under construction in Uzbekistan, there was some lack of these lines in the project. After knowing those, I checked with our stock and offered the shortest time we can make , made the very detailed offer including the stock items, total weight and dimension, several different plans to do the transportation to the customer. Soon the customer decide to place the order, and he told me there will be following orders from the same project.

How to inspect ASTM A312 TP304/304L pipe?
Appearance inspection
Dimensional deviation: Check whether the wall thickness, outer diameter, length and other dimensions of the stainless steel pipe meet the standards or contract requirements. You can use tools such as vernier calipers and tape measures to measure.
Surface quality: Check whether there are cracks, pitting, pores, slag inclusions, oxide scale, rust and other defects on the inner and outer surfaces of the stainless steel pipe. The surface of high-quality stainless steel pipes should be smooth and flat without obvious defects.
Welding quality: For welded stainless steel pipes, check the weld formation, size, mechanical properties of the welded joint, etc. The weld should be free of cracks, lack of fusion, pores, slag inclusions and other defects.
Chemical composition inspection
Spectral analysis: The chemical composition of stainless steel pipes is tested by a spectrometer to ensure that they meet the relevant standards or grade requirements. This is an important means of identifying stainless steel materials.
