The entire production process and shooting control of seamless steel pipe procurement, take you to observe in real time.

After the contract is signed, we start planning procurement, starting from the billet to control the quality, production cycle and delivery period of the steel pipe.

1. Billet procurement→

 

2. After the pipe is threaded, the first cold drawing is carried out, followed by heat treatment, and then the second cold drawing. Measure the wall thickness, outer diameter, take photos of the entire steel pipe, and send the production process and production progress to the customer in real time.

3. Perform spraying and length measurement. At this time, the customer will send a third party to inspect the finished product, including chemical composition, outer diameter, wall thickness, and various inspections of sealing.

4. After the inspection is passed, we will package and ship the steel pipe.

We will report and shoot the control and supervision of the entire production process to customers in real time, so that customers can rest assured and worry-free. There is such a team that helps you control the entire process. Please rest assured to give the entire order to us.
The first step of cooperation will give customers 100% peace of mind and peace of mind. Welcome your inquiries and messages.
