Boiler steel refers to the special steel used to manufacture pressure components of steam boilers, such as steam drums. The boiler steel mainly means boiler steel plates and seamless boiler steel pipes. Boiler components not only bear pressure loads but are also heated by direct fire, so the requirements on the chemical composition and mechanical properties of boiler steel, TB/T 1979 steel plate are strict. In the chemical composition of boiler steel, TB/T 1979 steel plate, sulfur and phosphorus are strictly controlled. Tensile strength, yield point, elongation, impact energy value and 180 ° cold bending are required to be tested in boiler steel mechanical properties. In addition, strain aging impact test is also required for boiler steel. The quality control of boiler steel is slightly higher than that of pressure vessel steel.
Medium and thick steel plates are widely used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and so on. However, each project has different requirements for plate size. How to cut TB/T 1979 steel plate, medium and thick steel plates? There are many ways, for example, flame cutting, laser cutting, wire cutting, plasma cutting, ultra-high pressure water cutting and so on.
In April 2018, our Philiphine customer purchased 1008 Tons API5 L Gr.B ERW&Q345B SMLS pipe TB/T 1979 steel plate for offshore oildfield resources drilling project. This is a regular demand almost two month, and we has been cooperated more than three times, totally around 2100 tons steel pipe since 2015 year.
