A brief introduction to the production steps of rolled pipes
The production of rolled pipes is a delicate and systematic process, which mainly includes the following key steps:
1. Material preparation: First, you need to select metal strips that meet the requirements as raw materials to ensure that the thickness, width, strength and other parameters of the material meet production needs.
2. Cutting and pretreatment: Cut the metal strip according to the predetermined length, and perform certain pretreatment, such as oil removal, rust removal, etc., to ensure the smooth progress of the subsequent rolling process.
3. Roll forming: The pretreated metal strip is fed into the rolling machine, and is gradually deformed into a hollow pipe through forced extrusion by three or more rollers. This step isRolled tubeThe core of production requires strict control of parameters such as roller pressure, temperature and speed.
4. Inspection and trimming: Conduct quality inspection on roll-formed pipes, including inspection of appearance, wall thickness, size, etc. If there are any defective products, they need to be repaired or re-produced.
5. Follow-up processing: According to customer needs, follow-up processing such as cleaning and painting is carried out on the rolled pipe to improve its corrosion resistance and aesthetics.
Through the above steps, rolled pipes that meet the requirements can be produced to meet the needs of various industrial fields.
