Expression method of pressure coefficient of seamless steel pipe: pressure P 17.5, coefficient S-4 seamless pipe production and manufacturing: tube blank -- Inspection -- peeling -- Inspection -- Heating -- perforation -- pickling -- grinding -- lubrication and air drying -- welding head -- cold drawing -- solution treatment -- pickling -- pickling and passivation -- Inspection -- cold rolling -- degreasing -- air drying -- internal polishing -- one external polishing -- Inspection -- identification of finished S690QL high yield steel product packaging.

The difference between S690QL high yield steel, Q420D steel and Q460D steel:
Q420D steel has good mechanical properties and weldability, good cold and hot workability. Q420D steel is mainly used for manufacturing mining machinery, heavy vehicles, ships, bridges, medium and high pressure boilers, vessels and other large welding and structural parts. S690QL high yield steel, Q460D steel has high strength, good plasticity and toughness, good weldability and good cold and hot workability. Q460D steel is mainly used for manufacturing engineering machinery components, such as mining machinery, forklift truck, transport vehicle, bridge, medium and high pressure boiler and other large-scale welding structural parts.

Our company mainly produce automobile steel plates, ordinary carbon low-alloy steel, container plates, ship plates, container plates, weathering steel, petroleum pipes, pipeline steel, S690QL high yield steel cold-rolled silicon steel, etc., which are widely used in various fields of the national economy.The BEBON brand is not only a symbol of strength, but also an embodiment of wisdom.
