1、 Main steam system pipes, pipe fittings, etc. (two high temperature and high pressure steam pipes between the outlet header of the superheater and the high pressure main valve interface);

2、 Hot reheat steam system pipes, pipe fittings, etc. (including primary and secondary reheat: two high temperature and high pressure steam pipes from the outlet header of the reheater to the interface of the medium pressure main valve);

3、Pipes and fittings of cold reheat steam system (including primary and secondary reheat: two high temperature and high pressure steam pipes between the steam exhaust port of the high pressure cylinder and the inlet header interface of the reheater);

4、High-pressure water supply system pipes, fittings, etc. (high-pressure boiler water supply pipes between the outlet of the electric feed pump and the inlet header interface of the economizer);

5、High pressure bypass system, medium pressure bypass system, low pressure bypass system and low pressure bypass system pipelines, pipe fittings, etc.;

6、 Pipes and fittings for water supply recirculation system, high bypass system, main steam and primary and secondary reheating hot section systems, drainage system, instrumentation system and sampling system;

7、Pipes, pipe fittings, etc. for molten salt heat storage and energy storage circulation system of CSP station;

1、 Gathering and transportation pipelines connecting oil wells and metering stations, combined stations in oil fields, pipelines inside oil refineries and oil depots, etc.;

2、Long-distance oil pipelines, pipelines for long-distance transportation of crude oil or refined oil. Its starting point and end point are respectively connected with oil fields, refineries and other oil companies. It consists of two parts: the oil station (including the first station, the last station, the intermediate pump station and the heating station, etc.) and the pipeline lines. The latter includes the main line pipeline part, and the cathodic protection system set up to prevent pipeline corrosion when passing through natural obstacles such as rivers, canyons, and seabeds.

The above systems involve seamless steel pipes (hot-rolled and cold-drawn), welded steel pipes, oil-resistant rubber hoses, etc.

1、 Gas gathering pipeline: the pipeline from the gas field wellhead device through the gas gathering station to the gas treatment plant or the starting gas compressor station;

2、 Gas pipeline: from the gas processing plant or the starting point compressor station of the gas source to the gas distribution centers in major cities, the pipelines of large users or gas storages, and the pipelines that connect with each other between the gas sources. Natural gas with quality standard (see pipeline gas transmission process) is the main part of the whole gas transmission system;

3、Gas distribution pipeline: the pipeline from the urban pressure regulating and measuring station to the user branch line;

The above systems include seamless pipes, spiral seam pipes and straight seam pipes. Seamless pipes are suitable for pipes with a diameter of 529 mm or less. The cross-sectional structure of the pipes of the gathering and transportation pipeline is complicated: the inner coating-steel pipe-outer insulation layer-thermal insulation (cold insulation) layer; the simple one is only the steel pipe and the outer insulation layer, while the inner wall coating and the thermal insulation (cold insulation) layer are all considered. The gas transmission process is further confirmed.

Condensate polishing system, urban domestic sewage treatment system, reclaimed water reuse system, seawater desalination system, etc. Involving pipeline products include but not limited to plastic-lined pipes, stainless steel materials, titanium alloy materials, copper alloy materials, steel polyethylene composite pipes , FRP pipes, etc.
