What is the material of 13Γ1С, the corresponding material of 13Γ1С-У, and the fixed rolling of 13G1S

13Γ1С is a Russian container steel plate,

13G1S steel plate fixed rolling: Wugang Xiangyang

13G1S continuous process, in which small and medium-diameter longitudinal welded pipes are made

of steel coils or connected steel plates in a discrete process, large diameter pipes are made of separate plates or welded plates, or multi-layer pipes are made of rims

The steel strip is leveled by connected horizontal rolls to remove shape defects (e.g. corrugation).

The welded strips form a circular strip. Semi-automatic submerged arc welding is used for this purpose and helps to form a strong and resilient weld with minimal defects. The resulting annular belt is fed into a looper.

The 13G1S steel strip is molded into tubes in a forming machine through a horizontal and vertical roll system. Each subsequent pair of rolls reduces the radius of the strip until its two edges are as close together as possible.

This product needs to be welded. One welding technique is high-frequency welding, in which the edge of the strip is heated to the melting point by a high-frequency electric current and then pressed by a pressure roller to form a strong and durable joint. High-frequency welding can be inductive or contact.

Deburring (external and internal) is performed to improve weld appearance and quality.

The tubes are cooled.

The 13G1S tubes are processed on a sizing machine:

by means of sizing rollers, sizing helps to round the tube and ensures precise tube geometry and shape.

Forming is used to produce shaped tubes by passing a round shape through a forming roller to obtain a rectangular or square shape.

Non-destructive testing of finished tubes may include magnetic, ultrasonic, eddy current, or X-ray methods.

The tube is cut to length at the cutting line.

These tubes are subject to quality control, finishing, and packaging. Visually inspect the surface of the tube. Remove the sample from the tube for testing. The pipe end may need to be chamfered. These tubes are packed and sent to the customer or warehouse. Heat treatment can be applied to welds or complete tubes.
