Steel pipe refers to the steel with openings at both ends and hollow section, and its length is larger than that of surrounding steel. According to the processing technology, it can be divided into seamless steel pipe and welded steel pipe, A709 Gr 50S bridge steel plate. The production methods mainly include hot rolling, cold rolling, extrusion, cold drawing, forging, welding, etc. The size range of steel pipe is very wide, from capillary with small diameter to large diameter pipe with several meters. Steel pipe can be used for pipeline, thermal equipment, mechanical industry, petroleum geological exploration, container, chemical industry and special purpose.
Q245R boiler steel plate introduction: Q is the first letter of "Qu" Chinese Pinyin; Number 245 is the yield strength value; R: is the first character of "Rong" Chinese Pinyin. Q245R steel is a special plate for pressure vessels and boilers with a yield strength of 245MPa. It has outstanding mechanical properties and processability. If you have special requirements, our company can supply Z15, Z25, Z35 and other Z performance tests.
No. 45 steel is commonly used medium carbon quenched and tempered structural steel. The cold plasticity of No. 45 steel is generally better than A709 Gr 50S bridge steel plate. Annealing and normalizing are better than quenching and tempering. No. 45 steel has higher strength and better machinability than Q345 steel. After proper heat treatment, it can obtain certain toughness, plasticity and wear resistance. No. 45 steel is suitable for hydrogen welding and argon arc welding, but not suitable for gas welding. Preheating is required before welding, and stress relief annealing shall be conducted after welding.
