3 PE High Grade Steel Pipe High Frequency Induction Welding API 5L Standard Tube Mill
Product Introduction
API pipe mill is specialized for manufacturing straight welded pipe for petroleum and gas pipelines. Taking hot-rolled steel as raw material, it produces required pipes through cold roll forming and suitable welding methods like H.F. welding, submerged arc welding, and so on. The whole production line adopts ‘ZTF’ forming technology.
Materials: L245,L360,A53,J55,N80 ,X42,X46,X52,X56,X60,X65,X70

Technology
ZTF is a kind of forming technology developed by Zhongtai Company in 2005, which absorbed the advanced technology from both domestic and international and then earn the “Technology Innovation Award” by China Cold Forming Steel Association.
Application
The API pipe mill is used to produce standard API pipes. They can be used for the extraction or injection of gas, oil, water, steam, etc., and can be classified as casing or tubing, depending on the application. The casing is used as a protective layer to help the well resist internal or external contaminants for durability. Tubing is used to inject or extract oil.
FAQ
Q: Are you a manufacturer?
A: Yes, we are a manufacturer. We have 4 factories ( Machining, Assembling, Heat treatment, and Moulding ). We also have our own R&D department. Welcome to visit us.
Q: What kind of payment term do you do?
A: We do T/T.
Q: What info do you need before giving me the price and proposal?
A: Since we design individual machines based on our customer's requirements, we need your desired products' basic dimensions, including all the pipe diameter(or tube length), thickness range, usage, raw material steel grade, coil weight, and degree of automation.
Q: What should I do if I just start a new business?
A: Contact us immediately, we provide a free consultant for pre-sales service. Also, we can help you solve the raw material (steel coil) purchase, worker training, international market price, and more.
Q: How do you do QA?
A: We have a special team to do strict QA, this is one of our strengths:
(1)Every gearbox will be tested for 8 hours with oil inside to guarantee there is no leak.
