Boiler steel pipe
Strong Strength, High-Quality Products
Boiler steel pipe

General boiler tube is mainly used to manufacture water wall tube, boiling water tube, superheated steam tube, superheated steam tube for locomotive boiler, large and small smoke pipe and arch brick pipe.

Boiler steel pipe application

1、General boiler tube is mainly used to manufacture water wall tube, boiling water tube, superheated steam tube, superheated steam tube for locomotive boiler, large and small smoke pipe and arch brick pipe.

2、 High pressure boiler tube is mainly used to manufacture superheater tube, reheater tube, guide pipe, main steam pipe, etc., of high pressure and ultra-high pressure boiler. The supply and demand trend of high pressure boiler tube industry is stable on the whole, but the supply and demand situation of each specific sub-industry will be further differentiated. Insiders point out that the most critical link is the use and promotion of new energy saving and heat preservation 20g high pressure boiler tube equipment.


The basic method of rust removal

1、 Cleaning.Using the solvent and emulsion to clean the surface of high pressure boiler pipe, so as to achieve the purpose of removing oil, grease, dust, lubricant and similar organic matter. But it cannot remove the dust, oxide skin, welding medicine and so on. So it is only as a supplementary method in the anti-corrosion production.

2、 Tool.Tool rust removal mainly use wire brush and other tools to grind the surface of high pressure boiler pipe. It can remove loose or warping of the oxide skin, rust, welding slag and so on. Manual tool can reach SA2 level, power tool can reach SA3 level. If the iron oxide scale attached to the surface, it cannot reach the anchorage depth required by the anti-corrosion construction.

3、Acid cleaning.High pressure boiler pipe generally adopt chemical and electrolytic methods to do pickling treatment.

4、Spray rust removal.Spray rust removal cannot only remove rust, oxide and dirt completely, but also high pressure boiler pipe can achieve the required uniform roughness under the action of abrasive impact and friction force.


Heat treatment methods applied in the boiler pipes

1、 Quenching

Hardening, also called quenching, is that high pressure boiler pipe is heated evenly to the appropriate temperature, then quickly immerse in water or oil for rapid cooling, and cooling in the air or in the freezing zone. So that the high pressure boiler pipe can obtain the required hardness.

2、Tempering

High pressure boiler pipe will become brittle after hardening. And the stress caused by quenching can make the high pressure boiler pipe tapped and broken. The tempering method can be used to eliminate brittleness. Although the hardness of high pressure boiler pipe is lighter reduced, its the toughness can be increased to reduce the brittleness.

3、Annealing

Annealing is the method to eliminate the internal stress of high pressure boiler pipe. The annealing method is that the steel parts need to be heated to the critical temperature, then put in dry ash, lime, asbestos or closed in the furnace, then let it cooling slowly.
