Product Description
Mainly used in the manufacture of high pressure and over pressure steam boiler pipes, etc. With high quality carbon structural steel, alloy steel and stainless heat resistant steel seamless steel tube, the boiler tube by the party under high temperature and high pressure pipe and works in high temperature flue gas and steam will happen under the action of oxidation and corrosion, so the steel pipe with high rupture strength, high oxidation resistance, Moreover, it has good organizational stability.
High pressure boiler tube production is not much different. Its main production characteristics are:
The pipe. Surface quality requirements are higher, to be peeled, peeled mm, some factories to take black repair grinding.
Cut off the tube blank. Steel later use flame cutting or copper cutting.
Heating. Poor thermal conductivity, so to control the furnace humidity. The heating temperature is generally U20 - H80℃.
Rolling. This kind of steel generally has good perforation performance and deformation parameters can be selected according to the middle carbon idle.
Heat treatment after rolling. This kind of steel pipe should be normalized and tempered after rolling. Some factories take hot rolling air cooling and then close the fire at 730-740℃.
The geometrical dimensions of steel pipe are required to be high, so as to ensure a good counterpart 59, and the length of steel pipe should be as long as possible to reduce the number of welding joints.
In the production of 20G high pressure boiler tube, the round tube billet is first beaten and annealed after being emptied. After annealing, special acidic liquid is used for pickling. After pickling, oil is applied. Then it is followed by multiple passes of cold billet tube, specialized heat treatment. After heat treatment, it is straightened. After straightening, the steel tube is sent by conveyor belt to metal flaw detector (or water pressure test) for internal flaw detection. If there are cracks, bubbles and other problems inside the steel pipe, it will be detected. Too strict manual selection. Number, specification and batch number of steel tube.
General boiler pipe is mainly used to manufacture water wall pipe, boiling water pipe, superheated steam pipe, locomotive boiler with superheated steam pipe, large, small smoke pipe and arch brick pipe.
High pressure boiler tube is mainly used to manufacture superheater tube, reheater tube, conduit pipe, main steam pipe and so on of high pressure and ultra high pressure boiler.
Manufacturing method of high-pressure boiler tube:
General boiler tube temperature is below 450℃, domestic pipe is mainly made of no. 10, 20 carbon bonded steel hot rolled pipe or cold drawn pipe.
High-pressure boiler pipe is often used in high temperature and high pressure conditions, the pipe in high temperature flue gas and water vapor, oxidation and corrosion. The steel pipe is required to have high durable strength, high oxidation corrosion resistance and good microstructure stability.
In the process of heating and cooling of high speed tool steel, if the quality process control of the product has problems, it may cause heat treatment defects of high pressure boiler tube, which will directly lead to scrap. Due to the high price of high speed tool steel, special attention should be paid to this kind of defects.
Overheat or overheat. The quenching heating temperature is too high, the insulation time is long, and the temperature control is inaccurate; Raw material carbide segregation is serious, local carbon content is too high; When heated in the salt bath furnace, the workpiece is close to the electrode; During quenching and heating, surface carburization or decarburization occurs.
