GB/T 5310-2017 Boiler & Pressure Pipe

Boilers and pressure pipes are core pressure-bearing components of special equipment (boilers, pressure vessels, pressure pipelines), specifically designed to transport high-temperature and high-pressure media (steam, hot water, gas, liquid, etc.). Their design, production, and use must strictly comply with special equipment safety standards. Their core characteristics are excellent high-temperature and high-pressure resistance, corrosion resistance, and structural sealing. They are indispensable key materials in industries such as power, chemical, energy, and pharmaceutical.

PRODUCT DETAILS

Boilers and pressure pipes are core pressure-bearing components of special equipment (boilers, pressure vessels, pressure pipelines), specifically designed to transport high-temperature and high-pressure media (steam, hot water, gas, liquids, etc.). They must strictly comply with special equipment safety standards in terms of design, production, and application. Their core characteristics include excellent high-temperature resistance, high-pressure resistance, corrosion resistance, and structural tightness. They are indispensable key materials in industries such as power generation, chemicals, energy, and pharmaceuticals.
