钝头镀锌带方管的特点介绍

国内应用较多的钢质管道防腐层有石油沥青、PE夹克及PE泡沫夹克、环氧煤沥青、煤焦油瓷漆、环氧粉末和三层复合构造、环氧煤沥青冷缠带(PF型)、橡塑型环氧煤沥青冷缠带(RPC型)等,目前推行应用广的几种管道防腐方式为三层PE复合构造、单层粉末环氧、PF型冷缠带、RPC型冷缠带。

There are many anticorrosive coatings for steel pipelines in China, such as petroleum asphalt, PE jacket and PE foam jacket, epoxy coal tar pitch, coal tar enamel, epoxy powder and three layer composite structure, epoxy coal tar pitch cold tape (PF type), rubber plastic epoxy coal tar pitch cold wrapping (RPC type). It is a three-layer PE composite structure, single-layer powder epoxy, PF type Cold-winding tape and RPC type Cold-winding tape.

1、石油沥青,原料普遍,价钱低。但劳动条件差,质量难以保证,环境污染严重。

1. Petroleum asphalt is a common raw material with low price. But the working conditions are poor, the quality is difficult to guarantee, and the environmental pollution is serious.

2、环氧煤沥青,操作烦琐,但掩盖层固化时间长,受环境影响大,不适于野外作业,10℃以下难以施工。

2. Epoxy coal tar pitch, which is cumbersome in operation, has a long curing time and is greatly affected by the environment. It is not suitable for field operation, and it is difficult to construct under 10 C.

3、环氧粉末防腐,采用静电喷涂方式,与同种资料防腐的管体熔结好,粘接力强,但环氧粉末防水性较差(吸水率较高,到达0.83%),给阴极维护设计带来一定的艰难。现场用具请求高,操作难度大,质量不易控制。

3. Anti-corrosion of epoxy powder, electrostatic spraying method, good fusion with the same anti-corrosion materials, strong adhesion, but poor waterproofing of epoxy powder (water absorption rate is higher, up to 0.83%), which brings some difficulties to cathode maintenance design. On-site appliances are demanding, difficult to operate and difficult to control.

4、3PE热缩资料,管道防腐密封性强,机械强度高,防水性强,质量稳定,施工便当,适用性好,不污染环境。PE吸水率低(低于0.01%),同时具备环氧强度高,PE吸水性低和热熔胶柔软性好等,有很高的防腐牢靠性,缺陷是:与其它补口资料本钱相比,费用高。

4. TPE heat shrinkage data, pipeline anti-corrosion sealing, high mechanical strength, strong waterproof, stable quality, convenient construction, good applicability, no pollution to the environment. PE has low water absorption (less than 0.01%) and high epoxy strength, low water absorption of PE and good softness of hot melt adhesives. It has high corrosion resistance and reliability. The defect is that it costs more than other materials.

5、PF型、RPC型冷缠带施工烦琐易行,配套的三种定型胶,使PF型环氧煤沥青冷缠带能够在任何环境、任何时节、任何温度条件下施工。

5. The construction of PF-type and RPC-type Cold-winding tapes is tedious and easy. The three kinds of setting glue can make PF-type epoxy coal tar asphalt Cold-winding tapes construct under any environment, any time and any temperature conditions.

6、冷缠带和3PE热缩带的特性是:适用各种资料主体防腐层管道,而其他方式适用于相同或接近资料的主体防腐层管道。

6. The characteristics of cold-wound tape and 3PE thermal shrinkage tape are that they are suitable for all kinds of main anticorrosive pipelines, while other methods are suitable for main anticorrosive pipelines with the same or close data.

其次随着开展有些管道在防腐时同时也需求保温,石油是很复杂的混合物,易腐蚀管道,防腐是有必要的,但是废品油管线在防腐的状况下也需求做保温,在东北和冬季,热胀冷缩会冻裂管道,影响稳定供给。

Secondly, with the development of some pipelines in anticorrosion, they also need heat preservation. Petroleum is a very complex mixture. It is easy to corrode pipelines. Anti-corrosion is necessary. But waste oil pipelines also need heat preservation under the condition of anticorrosion. In northeast and winter, thermal expansion and cold contraction will freeze and crack pipelines, affecting stable supply.
