Carbon steel boiler tube description

Carbon steel boiler tube for high pressure is a seamless carbon steel boiler tube.Generally used for high pressure boiler (working pressure is generally not greater than 9.8Mpa, working temperature between 450℃-650℃) heating surface pipe, collection box, economizer, superheater, reheater, etc. (P<9.8MPa,450℃), It is often applied to seamless carbon steel tube with minimum wall thickness for high pressure boiler and superheater.

Carbon steel boiler tube derusting method

(1) Cleaning: the use of solvents, emulsions to clean the surface of high-pressure boiler steel pipe, in order to remove oil, grease, dust, lubricant and similar organic matter, but it can not remove the surface of high-pressure boiler steel pipe rust, oxide skin, welding, so in the anti-corrosion production only as an auxiliary means.

(2) Tool derusting: mainly use wire brush and other tools to polish the surface of high-pressure boiler steel pipe, which can remove loose or warped oxide skin, rust, welding slag and so on. Hand tools can reach Sa2 level, power tools can reach Sa3 level, if the surface of the high pressure boiler steel pipe attached to the solid oxide sheet, the tool rust removal effect is not ideal, can not reach the anticorrosive construction requirements of anchor grain depth
(3) pickling: Generally using chemical and electrolytic two methods to do pickling treatment, pipeline anticorrosion only chemical pickling, can remove oxide skin, rust, old coating, sometimes it can be used as a sand blast after rust removal reprocessing. Chemical cleaning can make the surface reach a certain degree of cleanliness and roughness, but its anchor lines are shallow and easy to pollute the environment.
(4) Spraying (throwing) jet rust removal: spraying (throwing) jet rust removal is driven by a high-power motor to spray (throwing) jet blade high-speed rotation, so that the steel sand, steel shot, iron wire section, minerals and other abrasive on the surface of the steel pipe under the action of centrifugal force spraying (throwing) jet treatment, not only can completely remove rust, oxides and dirt, And the steel tube of high pressure boiler can achieve the required uniform roughness under the action of abrasive fierce impact and friction force.
