What are the influencing factors of flame cutting quality for S690QL pipe

Tempering the important S690QL pipe welding structure often use high temperature tempering to remove residual weld stress. Classification: high temperature tempering above 400 ℃, medium temperature tempering 250 ~ 400 ℃, low temperature tempering 150 ~ 250 ℃, Quenching +Tempering is improve S690QL pipe strength, plasticity and toughness.

The main advantage of weather resistant steel plate is its weathering ability. When exposed to the atmosphere, the weather resistant steel plate will form a anti-corrosion film on the surface, and prevent further corrosion to the steel S690QL pipe. Thus the weather resistant steel plate almost needs no paint treatment, which is the important measure for carbon steel plates to avoid going rust. Therefore, the maintance cost of weather resistant steel plate is low. The weather resistant steel plate is suitable for outside structure and construction use.

The company always adheres to the quality policy of "Quality First, Continuous Improvement, Customer Satisfaction" and the business philosophy of "Continuous Progress, Pursuing Excellence", as always, we look forward to cooperating with you to create a new situation for common development.Steel products S690QL pipe price concessions, rich industry experience, complete varieties.

Continue to refine and improve the company's common core values.Corporate values are the evaluation criteria for the production and operation behavior, products, services provided, social reputation and credit of enterprises, the biggest S690QL pipe goal pursued by enterprises and the criteria for judging things accordingly, and the core of corporate culture. Companies in the extraction of common value note: simplicity; Unity of coordination; S690QL pipe Systemic; Respect for talents; Focus on giving back to society; Try to make a factual argument in order to gain wider acceptance.
