聚氨酯保温管的母管两种除锈办法
Two Rust Removal Methods of Polyurethane Thermal Insulation Pipe
聚氨酯保温钢管的母管因临时表露在空气中，会呈现长绣的景象，而且还会影响保温钢管的防腐和运用寿命，那麼怎样对保温管停止防锈呢，上面我们就引见两种罕见的除锈办法。
The mother pipe of polyurethane insulating steel pipe will show a long embroidery because it is temporarily exposed in the air. It will also affect the anticorrosion and service life of the insulating steel pipe. So how to stop the rust prevention of the insulating steel pipe? Here we introduce two rare methods of rust removal.
喷丸处置技术是借助空气和高压水流，经过公用喷嘴，使磨料高速活动，冲击，摩擦，靠这种方式来肃清钢铁外表的铁锈，氧化皮，净化物和附着物，清算当时，钢铁不变色，而且会构成适合的清洁度和粗糙度。而针对钢材耗量大的锅炉，石化机械企业，通常采用抛丸处置技术，这是在高速旋转的抛头叶片作用下，磨料凭仗大的径向和切向速度来抛向钢铁外表，以此到达肃清杂质的目的。
Shot peening disposal technology is to use air and high pressure water flow through a common nozzle to make Abrasives move at high speed, impact and friction. By this way, rust, oxide scale, purifiers and adhesives on the surface of steel can be removed. At that time, the steel will not change color, and it will constitute a suitable cleanliness and roughness. For boilers and petrochemical machinery enterprises with large steel consumption, shot blasting technology is usually used. Under the action of high-speed rotating blades, abrasives are thrown to the steel surface by means of large radial and tangential velocities, so as to achieve the purpose of removing impurities.
保温异径管是在长间隔的保送蒸汽进程中添加管道后段压力时使用，也可以使在管线和管线口径呈现变化的时分使用停止焊接的。
The heat preservation pipe with different diameters is used when the pressure of the back section of the pipeline is added in the process of long interval steam transmission. It can also stop welding when the diameter of the pipeline and pipeline changes.
固定支架，每个补偿段都必需存在的，不可短少的配件，起到固定补偿器、衔接直管段的作用。
Fixed bracket, each compensation section must exist, not short of accessories, play the role of fixing compensator, connecting the straight pipe section.
补偿器起到管道热胀冷缩的补偿作用，防止管道伸缩发生焊口开焊，管道变形。
The compensator can compensate the thermal expansion and cold contraction of the pipeline, prevent the expansion of the pipeline from occurring weld opening and pipe deformation.
疏水阀可以合理的扫除管道内的凝结水，防止管道压力上升。
The trap can reasonably remove the condensate water in the pipeline and prevent the pipeline pressure from rising.
排潮管的作用是扫除保温层空间内的潮气，防止管道爆炸。一条合格的管线，保温管件的数量和长度、方向、压力、天文环境密不可分的。
The function of the tidal pipe is to sweep the moisture in the insulation layer space and prevent the pipeline from exploding. A qualified pipeline is inseparable from the quantity, length, direction, pressure and astronomical environment of insulation pipe fittings.
