聚氨酯保溫管的母管兩種除銹辦法
Two Rust Removal Methods of Polyurethane Thermal Insulation Pipe
聚氨酯保溫鋼管的母管因臨時表露在空氣中，會呈現(xiàn)長繡的景象，而且還會影響保溫鋼管的防腐和運用壽命，那麼怎樣對保溫管停止防銹呢，上面我們就引見兩種罕見的除銹辦法。
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.
噴丸處置技術(shù)是借助空氣和高壓水流，經(jīng)過公用噴嘴，使磨料高速活動，沖擊，摩擦，靠這種方式來肅清鋼鐵外表的鐵銹，氧化皮，凈化物和附著物，清算當時，鋼鐵不變色，而且會構(gòu)成適合的清潔度和粗糙度。而針對鋼材耗量大的鍋爐，石化機械企業(yè)，通常采用拋丸處置技術(shù)，這是在高速旋轉(zhuǎn)的拋頭葉片作用下，磨料憑仗大的徑向和切向速度來拋向鋼鐵外表，以此到達肅清雜質(zhì)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.
保溫異徑管是在長間隔的保送蒸汽進程中添加管道后段壓力時使用，也可以使在管線和管線口徑呈現(xiàn)變化的時分使用停止焊接的。
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，每個補償段都必需存在的，不可短少的配件，起到固定補償器、銜接直管段的作用。
Fixed bracket, each compensation section must exist, not short of accessories, play the role of fixing compensator, connecting the straight pipe section.
補償器起到管道熱脹冷縮的補償作用，防止管道伸縮發(fā)生焊口開焊，管道變形。
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.
疏水閥可以合理的掃除管道內(nèi)的凝結(jié)水，防止管道壓力上升。
The trap can reasonably remove the condensate water in the pipeline and prevent the pipeline pressure from rising.
排潮管的作用是掃除保溫層空間內(nèi)的潮氣，防止管道爆炸。一條合格的管線，保溫管件的數(shù)量和長度、方向、壓力、天文環(huán)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.
