Sell Boiler Tubes

Description

Boiler tubes is a one of seamless pipe. Manufacturing methods is the same as seamless tube, but it has the stringent requirements for manufacture of steel pipes. According to the temperature level,boiler tube is divided into general boiler tubes and high pressure boiler tube.

Production methods:
① general boiler tube temperature is below **0 ℃, using hot-rolled pipe or cold drawn tube manufacture steel pipe.
â‘¡ high-pressure boiler tube is used often in conditions of high temperature and high pressure pipe, the effect of high temperature flue gas and water vapor, oxidation and corrosion. Steel pipe with high rupture strength, high resistance to oxidative corrosion and have good organizational stability.

Boiler tubes purposes:
â‘  general boiler tubes is mainly used to manufacture water wall tubes, tubes in boiling water and superheated steam pipe, superheated steam locomotive boiler tubes, large and small smoke pipe and pipe arch brick.
â‘¡ high-pressure boiler tube is mainly used to manufacture high pressure and ultra-high pressure boiler superheater tubes, reheater tubes, airway, the main steam pipe.

Category:
General boiler tubes and high pressure boiler tube boiler tubes is exposed to high temperature performance. Boiler tubes in general, or high-pressure boiler tubes according to their use can be divided into a variety of steel pipe.
 

Heat exchanger is transfering the part of the heat of the hot fluid to cold fluid device, also known as heat exchangers. The heat exchanger is general equipment of the chemical, petroleum, power, food and many other general equipment  and plays an important role in production. Heat exchangers in chemical production can be used as a heater, cooler, condenser, evaporator and reboiler, etc., applied more widely. Many types of heat exchangers, but basically cold and hot fluid heat exchange principles and methods can be divided into three categories namely: partitions, hybrid and regenerative. In the three types of heat exchangers, the Partitions heat exchanger applications.

The role of the heat exchanger cold refrigerant will be sent to the pipeline of fresh air in the heat exchanger for heat exchange of fresh hot air into the pipe into the required low temperature. The boiler is heating, indoor winter need heating should be used.

The heat exchange tube means including low and medium pressure boiler seamless pipe (GB********9), on behalf of the material is on the *0th, the *0th of steel; high pressure boiler seamless pipe(GB********5), on behalf of the material for the *0G *2Cr1MoVG *5CrMoG and so on. This pipe through the wall for heat exchange, including boiler tube.heat exchanger tube.
 

High-pressure steel pipe is used in manufacturing high quality carbon steel of high pressure vessels and piping,alloy structural steel and stainless steel seamless pipe. Manufacturing methods are divided into hot-rolled (extrusion, expansion) and cold drawn (rolled). Among them, touter diameter of hot-rolled(extrusion,expansion) steel tubes range is 2.0 ~ *0mm;outer diameter of cold drawn (rolled) steel pipe range is *0 to **8mm;wall thickness range of 2.0 ~ *3mm.

Application of high-pressure steel pipe: high-pressure steel pipes have a good room and high temperature mechanical properties, strict quality control,which is suitable for a variety of high-pressure conditions in the workplace. The high-pressure pipe is mainly used for boilers, high pressure fuel pipe, fertilizer, equipment and piping and other fields.
