As a sophisticated steel pipe producer in China, we often conduct the second testing in advance. Before production, choosing and checking the suitable raw material is fundamental to the overall construction project. In terms of checking, do you know the testing aspects it contained? At first, we may check the surface of our products to avoid obvious scratching or rusting. It is well known to us that steel pipe surfaces should be evenly without grease or oil. Smooth surface is benefit to make a tight-fitting components. Secondly, gauging thickness is also involved in the testing process. Thickness must be precise in order to accord with the requirement of you. Besides, zinc layer is also very important for customers. Last but not the least, we can have third party checked our steel pipes according to the request of customers.
