S690QL vs S690QL1 vs A572 Grade 50 steel

15Mo3 steel manufacturing method: adopt oxygen top blown converter method, 182 open hearth method or 3666 to smelt in 3769 electric furnace. After negotiation with the customer, other equivalent methods can also be adopted.15Mo3 steel is used for heating surface pipes, economizers, superheaters, reheaters, etc. of high-pressure boilers S690QL vs S690QL1 (working pressure is generally above 9.8MPa, working temperature is between 450 ℃ ~ 650 ℃).

The selection principle of steel plate for high-rise building is: it can not only make the structure safe and reliable, but also can save steel and reduce the cost. Different use conditions should have different quality requirements. In terms of the mechanical properties of steel such as S690QL vs S690QL1, yield point, tensile strength, elongation, cold bending property, impact toughness etc. are the indicators to measure the quality of steel. In the design of steel structure, the appropriate steel should be selected according to the characteristics of the structure. The selection of steel is not only an economic problem, but also related to the safety and service life of the structure.

During the construction of hot-dip S690QL vs S690QL1 galvanized pipe, the correct welding process shall be adopted, the inspection and acceptance shall be carried out in strict accordance with the specification, and the anti-corrosion treatment (zinc rich paint) shall be done timely after the welding is completed. It is feasible in the construction process of open and closed air conditioning system, which can improve the S690QL vs S690QL1 construction speed and the firmness of the pipe connection. Therefore, the hot-dip galvanized pipe can be welded and connected under the construction conditions and on the premise of relevant protection and anti-corrosion measures.
