PVQ DIN 17155 HI boiler steel plate Carbon Steel Supplier

PVQ DIN 17155 HI boiler steel plate,A387Gr91Cl2 pressure vessel plate is equivalent to the Chinese grade 10Cr9Mo1VNbN steel. , A387Gr91Cl2 alloy steel plate not only has high oxidation resistance and high temperature steam corrosion resistance, but also has good impact toughness and high and stable durable plasticity and thermal strength performance. When the use temperature is lower than 620 ℃, its allowable stress is higher than that of austenitic stainless steel, ,PVQ DIN 17155 HI boiler steel plate.

Q345R material is a special steel grade for pressure vessels with a yield strength of 340MPa It has good comprehensive mechanical properties and technological performance The phosphorus and sulfur contents are slightly lower than the low-alloy high-strength steel plate Q345 (16Mn) steel In addition to the increased tensile strength and elongation requirements compared to Q345 (16Mn) steel, it also requires impact toughness Q345R steel plate is currently the most widely used and most used steel plate for pressure vessels in China,PVQ DIN 17155 HI boiler steel plate.

PVQ DIN 17155 HI boiler steel plate,During the construction of hot-dip 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 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.
