Company Information:
Yantai Xinpeng steel pipe co,.ltd. top 5 manufacture on the precision steel tube in China, We establish in 1992, from 2002 we begin to work on the hydraulic cylinder tube . We sell the seamless tube, agency of marcegaglia’s Dom tube. We have passed ISO9001:2008 since 2010. Xinpeng Persons all trust Honesty, credit is more important than business itself. We have cooperate with many clients from all over the world, Dongyang Corporation, Lonkon, China Heavy Truck, New star, Faster are all our clients, Xinpeng know technology is and cost reeducation is very important to China’s enterprise. Our main products is cold drawn/rolled steel tube, can do anneal by ourselves, honing and Srb process we all can work also. Any need, welcome to give us inquiry, we will give our best quotation.

Surface Treatment | bare, varnished, oiled, anti-corrosion coating as request |
Packing | 1. bundle packing 2. marking as per customer's requests 3. paint on the pipe as per customer request 4. pipe caps as customer request |
Condition of Delivery | 1. NBK(+N) after cold forming, eventually above phase transition point, in a protective atmosphere of annealing oxidation medium 2. GBK(+A) after cold forming, annealing in non oxidizing medium protective gas 3. BK(+C) the final heat treatment after cold forming, therefore small steel pipe plastically, the plastically degree does not guarantee 4. BKW(+LC) after final heat treatment, a tiny cold drawing deformation, continue again when machining steel pipe allowed inside certain limits cold deformation(bending, flaring) 5. BKS(+SR) have a stress relief after cold forming, heat treatment, steel pipe can be carried out within a certain limit in the appropriate processing again |
