Production process
.Raw material preparation:
Choose the appropriate alloy steel or stainless steel material, usually available in coil or billet form.
.Cutting:
Cut raw materials into appropriate lengths for subsequent forming and processing.
.Molding:
Using hot rolling or cold rolling process, the cut material is processed into the preliminary shape of square tube through rolling machine or forming machine.
.Welding:
For welded alloy square tubes, arc welding, laser welding or high frequency welding are used to weld the edges of the square tubes together to form a closed tube body.
.Cooling:
After welding, the square tube needs to be cooled to ensure the strength and stability of the welded joint.
.Straightening:
The square tube is straightened by a straightening machine to ensure its straightness and dimensional accuracy.
.Cutting and trimming:
Cut the square tube to the required length and perform edge trimming to remove burrs and irregularities.
.Surface treatment:
According to customer needs, surface treatment such as hot-dip galvanizing, plastic spraying, painting, polishing, etc. is carried out to improve corrosion resistance and aesthetics.
.Inspection:
Carry out quality inspection on finished products, including size, appearance, welding quality, etc., to ensure compliance with relevant standards and customer requirements.
.Packaging and Shipping:
Pack the alloy square tubes and prepare to ship to customers.
