接口处的涂层有十分严厉的技能要求,在.0MPa压力下,不会发作渗漏,防功用有牢靠的确保。电缆穿线用涂塑管而衬塑钢管正本就是两层组成,即使聚乙烯衬管粘结力也远小于涂塑管的粘结力,电缆穿线用涂塑管在热胀冷缩的状况下很简略就会发作分层。且其接口处不管是丝扣仍是法兰联接都是薄弱环节,塑管和钢管之间就会锈蚀钢管,构成全体管路防失效,大大削减运用寿数。由于涂塑管和衬塑钢管的加工方法和所用资料不同,构成了运用寿数和价格的差异。涂塑管各项功用目标远比衬塑钢管为好。由于涂塑管所用涂料价格较高。加工方法杂乱,费用较高,所以比衬塑钢管的商场价稍高。涂塑管的质量更好,故障率低,运用寿数比衬塑钢管要长。

The coating at the interface has very strict technical requirements. Under the pressure of. 0 MPa, it will not leak, and the function of anti-leakage is firmly ensured. Plastic-coated pipe is used for cable threading and plastic-lined steel pipe is composed of two layers. Even if the bonding force of polyethylene lining pipe is far less than that of plastic-coated pipe, the plastic-coated pipe for cable threading will simply occur stratification under the condition of thermal expansion and cold contraction. The connection between plastic pipe and steel pipe will corrode the steel pipe, which constitutes the whole pipeline anti-failure and greatly reduces the service life. Due to the different processing methods and materials used for plastic coated pipe and plastic lined pipe, the difference of service life and price is formed. The function target of plastic coated pipe is far better than that of plastic lined pipe. Because of the high price of the coatings used in the plastic pipe. The processing method is messy and the cost is high, so it is slightly higher than the market price of plastic-lined steel pipe. The quality of plastic-coated pipe is better, the failure rate is lower, and the service life is longer than that of plastic-lined pipe.

表里涂塑管厂家选用表里均有涂塑维护层,为增焊接钢管或无缝承压钢管的复合结构,克服了钢管自身存在的易生锈、、高污染、及塑料管度低、易变形的缺点,整合了钢管和塑料的一同长处,归于推行运用的环保.涂塑管现在广泛运用于市政建造、房地产职业、消防体系、通讯、电力、石油、化工、燃气、煤矿、高速公路等要点建造工程的给水、排水、电缆铺设、石油燃气运送、排放等,并能运用于火力发电厂脱硫体系、锅炉体系、海水循环体系日运送管道。以无缝钢管、焊接钢管为基管,内壁涂装高附着力、防腐、食品级卫生型的聚乙烯粉末涂或环氧树脂涂料。表里涂塑管厂家,是本公司引入国外的工艺和技能,自主研发开发的新式,属国内首创的用改环氧树脂粉末,对钢管内、外壁进行涂敷,涂层耐温功用优异,可在杠0℃-00℃长期运用,并且不焚烧,不软化。

In order to increase welded steel pipe or seamless pressure steel pipe composite structure, the exterior and interior plastic pipe manufacturer chooses the exterior and interior plastic coating maintenance layer, overcomes the shortcomings of the steel pipe itself, such as easy rusting, high pollution, low degree of plastic pipe and easy deformation, integrates the same advantages of steel pipe and plastics, and attributes to the environmental protection of implementation and application. Plastic coating pipe is now widely used in municipal construction, real estate profession, fire fighting body. It can be used in water supply, drainage, cable laying, oil and gas transportation and discharge of key construction projects such as communication, power, petroleum, chemical industry, gas, coal mine and highway, and can also be used in daily transportation pipelines of desulfurization system, boiler system and seawater circulation system in thermal power plants. With seamless steel pipe and welded steel pipe as the base pipe, the inner wall is coated with high adhesion, anti-corrosion, food-grade sanitary polyethylene powder coating or epoxy resin coating. The exterior coated plastic pipe manufacturer is a new type developed independently by introducing foreign technology and skills. It is the first domestic modified epoxy powder to coat the inner and outer walls of steel pipes. The coatings have excellent heat resistance. They can be used for a long time at the bar temperature of 0-00 C without burning or softening.

消防给水(气体)涂塑管道是钢塑结合的,一同具有钢管和塑料管的长处,其度高,刚好,压力度高;由于内壁涂塑,所以表里表光滑,流体阻力小,流量大。消防给水(气体)涂塑管道具有的耐化学、耐水和耐抗溶、蛋白、高倍数泡沫救活剂,处理了因输水、埋地和酸、碱、盐对金属管道的,大大前进了管道的运用寿数。排水涂塑管是专关于给排水而研发的一种新式复合管材,该复合管道归纳了各种管道的特征,既有钢管的钢度和硬度,又有塑料管的耐磨、耐、系数小等长处,是一款价比十分高的绿色节能管材。被广泛用在工业给排水、日子给排水、海水处理、暖通循环水及化工流体运送等范畴。被称为之为“优质绿色建材”称谓。涂塑管的联接有三种多见方法,分别是丝扣联接、法兰联接、沟槽联接。

Fire water (gas) coating pipe is steel-plastic combination, with the advantages of steel pipe and plastic pipe, its degree is high, just, high pressure; because of the inner wall plastic coating, so the surface and inner surface is smooth, fluid resistance is small, flow rate is large. Fire-fighting water (gas) coating pipeline has chemical resistance, water resistance and solubility resistance, protein, high multiple foam activator, which can deal with metal pipelines due to water transportation, burial and acid, alkali and salt, thus greatly advancing the service life of pipelines. Drainage plastic-coated pipe is a new type of composite pipe developed for water supply and drainage. It summarizes the characteristics of various pipes, including steel and hardness of pipes, wear resistance, resistance and small coefficient of plastic pipes. It is a green energy-saving pipe with a very high price ratio. It is widely used in industrial water supply and drainage, daily water supply and drainage, seawater treatment, HVAC circulating water and chemical fluid transportation. It is called "high quality green building materials". There are three common methods for the connection of plastic-coated pipes, which are threaded connection, flange connection and groove connection.
