The main steel plates for oil and gas pipelines are X42, X46, X52 (L360), X56 (L390), X60 (L420), X65 (L460), X70, X80. The specification range of steel plate used by the company for oil and gas pipelines: thickness 8mm-60mm. It can produce additional flaw detection requirements and Z15-Z35 tear resistance (thickness direction performance) steel plates A709 Gr 50 low alloy steel sheet, and can also provide Z-direction performance steel plates according to ASTM A770 and other standards.
Standing at a new historical starting point, we adapt to the requirements of supply side structural reform, adhere to the overall strategy of "innovation driven, quality leading, A709 Gr 50 low alloy steel sheet quality improving and efficiency increasing, transformation and development", and constantly improve the development concept and development level with a forward-looking vision and grand vision. Now we have been ranked the A709 Gr 50 low alloy steel sheet International leading steel materials supplier.
S355NC steel offers excellent bending, flanging, cold-bordering and folding A709 Gr 50 low alloy steel sheet properties in both longitudinal and transverse direction. The bending radii specified below should be observed as minimum values.
Rolled sheet is a very common material in industrial construction. Rolled sheet at room temperature is cold-rolled sheet, and cold-rolled sheet is the rolling of hot-rolled coils below the recrystallization temperature. The hot-rolled sheet is rolled above the recrystallization temperature. So what is the difference between A709 Gr 50 low alloy steel sheet, hot rolled sheet and cold rolled sheet?
We should focus on the main problems to be solved and pay attention to efficiency. After receiving the user's quality objection report data, the possible causes, responsible units, compensation amount, etc. of the problem shall be judged based on experience. To have a clear service plan, to be clear about what your main problem is, what technical support is needed, these should be prepared.
