With those well-appointed equipment and molds as well, we can provide customers with different kinds of products matching with diversified customization. Our molds are designed for specific specifications with high technology. For example, we can make elliptical tube, bread pipe as well as quincunx pipe accessible. Other complicated shape is also available. So if your requirements or projects are special, you can place an order in certain quantities with us without hesitation. Our molds can control errors in minimum range to tally with your standards. Certainly, our molds will have an increase in the near future, about 2 years.2-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.
