Rolling process flow of Q235B semi round steel pipe

1. Pre bending of coiled tube: Operation process: After aligning the position of the sheet metal, strictly use the speed suitable feed method and multiple feed method for pre bending, adjust the position of the upper roller (on the three roll plate machine), and make the ends of the sheet metal produce preliminary bending.
2. The process of rolling pipes and plates: After the sheet metal undergoes initial bending, it then rolls back and forth to bend. Gradually press down the upper roller and roll back and forth to gradually reduce the curvature radius of the sheet metal until it meets the specified requirements.
3. Tube inspection: During the forming process, the operator should occasionally use a standard template to check whether the curvature is qualified, and to check the straightness of the bent parts of the steel plate. After each piece is pressed, the quality inspector should check the outer diameter and meet the following standards: Round tube: D/500 and ≤ 5mm.

The function of rust proof oil for thick walled coiled pipes is to prevent rust, which can make the thick walled coiled pipes smooth and new for a long time, reducing external corrosion on them. Secondly, to increase its sealing performance to a certain extent, so that there will be no leakage problems when transporting fluids. There are also materials that have stable performance or are not afraid of sun exposure. In weather conditions such as sun exposure and continuous rainy weather, many material properties may change. However, the use of rust proof oil now isolates thick walled pipes from direct contact with air, reducing the chance of changes due to external conditions and increasing their stability and ease of use.

Brushing anti rust oil can meet customer needs by selecting the type of anti rust oil that can be stored for a certain period of time, making it easy to use and reducing the occurrence of accidents
