|Product Name:||A335 P91 Seamless Heat Exchange High Pressure Boiler Tube||Technique:||Hot Rolled|
A335 carbon seamless steel pipe,
P91 carbon seamless steel pipe,
Seamless carbon steel boiler tubes
We are specialized in supplying high pressure boiler tube tube for more than 10 years and have rich experience. We own professional technicians and engineers, professional testing equipment, rich experience in delivery. We have more than 10 years of cooperative customers.
Our high pressure boiler tubes are usually operated under high temperature and high pressure, and pipes are exposed to high temperature smoke. Oxidation and corrosion occur under the action of gas and water vapor. Therefore, the steel pipe is required to have high durability, high oxidation resistance, and good structural stability. In addition to ensuring chemical composition and mechanical properties, the high pressure boiler tube must have The hydraulic test is carried out one by one, and the flaring and flattening tests are to be carried out.
