Nuclear Power

RCC-M Qualified

ASME Section III Certified

Our stainless steel and nickel alloy steel products are used in nuclear industry of the quality class I, II, III; Nuclear power is only possible by most strict quality of the construction materials and none are more important than the stainless steel pipes which carry steam at high pressure and high temperatures. In the mean time, most of the nuclear power stations are located at coast and use sea water for cooling which require pipe and tubes have good resistant ability to the corrosiveness of salt water.

Main Standard and Grades for Nuclear Application:

and other grades with modified chemical composition as per specifications.

In nuclear industry, the pipes and tubes are divided into three sub-segments based on application and specific requirements:

1. Nuclear Steam Generator

2. Nuclear Heat exchanger

3. Nuclear Pipelines

Typical products:

Big diameter pipeline

Small diameter instrumentation tubes

U-bend and straight heat exchanger tubes

Π-shape heat exchanger tubes

Spiral coiled tubes

Thermal Power

In the thermal power stations, our tubes and pipes are mainly used for boiler units, both sub-critical and super critical boilers, and Heat Recovery Steam Generator(HRSG) sectors. Tube for thermal power applicaiton need to withstand high pressure and temperature. Our company have provided quality tubing in cold drawn as well as hot finished for the power generation industry and to the world’s premier equipment suppliers. We have experts to help with material selection and specifications to ensure that you get exactly what you need for your unique application.

Main Standard and Grades for Thermal Power Application:

Standard:

ASME SA213, ASME/ASTM SA/A312

Grade:

Carbon steel

T1, T11, T22, T91

P9, P91, P22, P11

TP304H, TP347H, TP347HFG, Super304H, HR3C

In Thermal Power industry, the pipes and tubes are used in following power plants:

Coal-fired power plants

Gas-fired power plants

Co-generation and industrial plants

Tubes are mainly used in the equipment as:

Steam Boiler tubes

Reheater tubes

Superheater tubes

Condenser tubes

LP/ HP Feed water heater tubes

LP/ HP Heat Exchanger tubes

Main Steam line

Renewable Power

Renewable thermal energy is the technology of gathering thermal energy from a renewable energy source for immediate use or for storage in a thermal battery for later use, the renewable power generation is becoming more and more important in the human life.

Our company make big investment of R&D on this application and now we can offer a wide portfolio of tubes and pipes to this field.
