钢塑管是本公司专业生产的产品之一,产品有着非常良好的 属性,在使用的过程中,这样在使用的过程中,也能够有更好的使用效果,产品需要拥有的属性是哪些呢, 其中最重要的就是防腐属性,防腐的必要性是什么呢。
 
Steel-plastic pipe is one of the products specially produced by our company. The product has very good attributes. In the process of using, it can also have better use effect. What attributes should the product have? The most important one is the anti-corrosion attributes. What is the necessity of anti-corrosion?

Necessity of Anti-corrosion of Steel-Plastic Pipe
 
 
 
用合金钢铲子将气柜上的原旧漆皮全部根除。这种氧化层极薄,透过它能够看到等径三通外表的天然 光泽,使等径三通具有共同的外表。用钢丝刷子焊缝,增强板及其它死角部位的内锈除净。涂层对基体的附 着力是评价涂层耐侵蚀机能的重要指标,附着力越强,抗侵蚀性越好,涂层越耐久。外表处置工作完毕。可 涂刷环氧煤沥青底漆二遍,以防受潮生锈。用丙酮或其它易挥发清洗济除去气柜外表上的油、焦油及其它污 物。内外涂塑钢管清洗洁净后外表应到达枯燥、无油无污物。
 
Use alloy steel shovel to eradicate all the old paint on the gas holder. This kind of oxide layer is very thin, through which we can see the natural luster of the appearance of the equal-diameter tee, so that the equal-diameter tee has a common appearance. Use steel wire brush to weld seam, reinforcement plate and other dead corner parts to remove internal rust. The adhesion of the coating to the substrate is an important index to evaluate the corrosion resistance of the coating. The stronger the adhesion, the better the corrosion resistance and the longer the coating lasts. The external disposal is completed. Epoxy coal tar pitch primer can be painted twice to prevent dampness and rust. Use acetone or other volatile cleaning agent to remove oil, tar and other dirt from the outside of the gas holder. After cleaning the inner and outer plastic-coated steel pipes, their appearance should be dry, oil-free and pollution-free.
 
 
 
目前钢塑管在人们的建筑中的应用非常广泛,特别是一些大型的建筑工程。因此在施工的前期就应该 对所采购的产品进行检查和检测。将铝带通过四套冷弯模和两个成型辊形成圆形管状搭接(或对接)在一起, 用超声波焊接或员弧焊接,然后退过挤出机挤出内外层塑料管和粘合剂,再通过特制的共挤复合管机头将塑料管分别复合在已焊接的铝管内外表面上。 把塑科管以松配合插入稍大尺寸的金属管中,然后送入冷拔机,施加高压压缩金属管,使两者紧密贴合。可 以在金属管内壁开设无数个孔穴或微小的倒钩,使这些微小的触点镶嵌于塑料管表面内,可提高复合管对热 应力的抵御。
 
At present, steel-plastic pipes are widely used in people's buildings, especially in some large-scale construction projects. Therefore, the purchased products should be inspected and inspected in the early stage of construction. The aluminium strip is lapped (or butted) by four sets of cold bending dies and two forming rolls, welded by ultrasonic wave or arc welding, then extruded by the extruder, the inner and outer plastic pipes and adhesives are extruded, and then the plastic pipes are combined on the outer and inner surfaces of the welded aluminium pipes by a special co-extrusion compound pipe head. The plastic pipe is loosely fitted into a slightly larger metal pipe, and then fed into a cold drawing machine to compress the metal pipe under high pressure, so that the two closely fit. Countless holes or tiny barbs can be opened in the inner wall of the metal pipe to make these tiny contacts embedded in the surface of the plastic pipe, which can improve the resistance of the composite pipe to thermal stress.
 
 
 
钢塑管拥有良好的防腐性,能够在后期的工作中,更好的将人们的工作完成。其外表的一层防腐作用 的涂料,是用特殊的材料制成的。由于钢塑管良好的防腐性,是人们在选购的过程中,首选的产品之一。
 
The steel-plastic pipe has good anticorrosive property and can better finish people's work in the later stage. A coating of anticorrosive coating on its exterior is made of special materials. Because of the good anti-corrosion property of steel-plastic pipe, it is one of the preferred products in the process of purchasing.
