CHEMICAL INDUSTRY

Stainless steel pipes play a crucial role in the chemical industry due totheir corrosion resistance, high-temperature and high-pressure resis-tance, as well as energy conservation and environmental protection.They are widely used in reactors and heat exchangers, storage tankequipment, heat exchangers, and corrosive medium transportation sys-tems. The extensive application of stainless steel pipes not only ensuresthe safety, efficiency, and environmental friendliness of the chemicalproduction process but also provides a solid guarantee for thelong-term stable operation of chemical equipment with its excellentperformance and reliable connection technology.

CHEMICAL INDUSTRY FIELDS：

Petrochemicals, Coal Chemicals, Biochemicals, Pharmaceutical Chemicals

PETROLEUM

Thanks to its outstanding cor-rosion resistance, highstrength, and good mechani-cal properties, stainless steelpipes demonstrate unparal-leled advantages in the petro.leum industry. They can oper-ate stably over the long termin harsh environments, ensuring the efficiency and safety ofoil production while reducingmaintenance costs.With thedevelopment of the petroleumindustry, the demand forstainless steel pipes is increas-ing day by day, and their corestatus is becoming moreprominent.

NUCLEAR POWER/NUCLEAR INDUSTRY

Stainless steel pipes are extensively and crucially applied in the fields of nuclearpower and the nuclear industry, due to their excellent corrosion resistance, highstrength, and good mechanical properties, making them the preferred material forthese key areas. In nuclear power, stainless steel pipes are widely used in steam gen-erator heat transfer tubes, primary loop main pipelines, passive residual heat removalheat exchangers, and reactor pressure vessels among other critical components. Inthe nuclear industry, stainless steel pipes are often used to manufacture heatexchangers, pipelines, containers, and nuclear waste storage wells, providing strongsupport for the safe utilization of nuclear energy.

OFFSHORE ENGINEERING VESSELS

As global environmental degradation and water scarcity issues intensify, the impor-tance and broad prospects of seawater desalination have become prominent; mean-while, marine engineering has flourished thanks to the development of oil and naturalgas resources, and shipbuilding has shown unlimited potential driven by the globaleconomy. Stainless steel and special alloy pipe materials, with their outstanding cor-rosion and acid resistance characteristics, exhibit a wide range of application value inthese fields. They play a crucial role in seawater desalination equipment, marine engi-neering facilities, and shipbuilding components, providing strong support for thedevelopment of these areas.
