消防涂塑钢管良好耐化学稳定性和耐水性,具有减阻、防腐、抗压,抗菌等作用。它一般是不受输送介质的制约,涂塑层与钢铁有极强结合力。涂层材质:环氧树脂(EP)适用于80℃以下工作环境,钢管涂层有极高附着力,其涂层硬度高、耐冲击性好,且是有较好的耐化学腐蚀性能。
 
Fire-fighting plastic-coated steel pipe has good chemical stability and water resistance. It has the functions of drag reduction, anticorrosion, compression resistance and anti-bacterial. It is generally not subject to the constraints of transport media, plastic coating and steel has a strong bonding force. Coating Material: Epoxy resin (EP) is suitable for working environment below 80 C. The steel pipe coating has high adhesion, high hardness, good impact resistance and good chemical corrosion resistance.
 
涂塑复合钢管,我们通常是指双面涂塑,也称内外涂塑管,对于涂塑复合钢管而言,前期除锈工艺对成品管的质量起着至关重要的作用。所以选用新出场的钢管,不需要镀锌,但要将锈蚀出去,管内有少量的锈斑也需要除净。而且要有无,最低达到除锈St2或者电动除锈Sa1级要求。去除钢管表面的油污,我们可以使用对表面进行清洁。
 
Plastic-coated composite steel pipes, we usually refer to double-sided plastic coating, also known as internal and external plastic coating pipes, for Plastic-Coated composite steel pipes, the pre-rust removal process plays a vital role in the quality of finished pipes. Therefore, it is not necessary to galvanize the new steel pipe, but a small amount of rust spots in the pipe need to be removed if the rust is to be removed. The minimum requirement is St2 or Sa1 for electric rust removal. To remove the oil stain on the surface of steel pipe, we can use it to clean the surface.
 
 
 
作为内外涂塑钢管更具安全性,聚乙烯的高效绝缘性使得电线的使用安全性更高,而且涂塑钢管能够将电线和环境进行隔离,所以电线在使用的时候不会受任何影响,小区的供电环境在涂塑钢管的保护下也将更安全。
 
As the inner and outer plastic-coated steel pipe is more safe, the high-efficiency insulation of polyethylene makes the use of wire safer, and the plastic-coated steel pipe can isolate the wire and the environment, so the wire will not be affected in use, and the power supply environment in the residential area will be safer under the protection of the plastic-coated steel pipe.
 
 
 
消防涂塑钢管厂家钢管机械性能优异涂塑钢管延续了钢管的优点,其机械强度高,对冲击,弯曲等外来影响具有很强的承受能力,可以承受苛刻的使用条件,安全性高。
 
Fire-fighting plastic-coated steel pipe manufacturer's excellent mechanical properties of steel pipe continue the advantages of steel pipe, its high mechanical strength, impact, bending and other external effects have a strong bearing capacity, can withstand harsh use conditions, high safety.
 
 
 
耐化学腐蚀性能突出,系统整体防腐效果好涂塑钢管具备钢管和塑料管的双重优点,塑料涂层具有很强的耐酸碱性,耐土壤腐蚀及耐候性能,适用于煤矿井下输送含硫,钙,镁以及其他腐蚀性介质的流体。良好的卫生性能 采用的改性食品级环氧树脂粉末(EP)涂层,或聚粉末(PE)形成的涂层,无味,可达到直饮水。
 
The plastic coating has strong acid and alkali resistance, soil corrosion resistance and weather resistance. It is suitable for conveying fluids containing sulphur, calcium, magnesium and other corrosive media in underground coal mines. Modified food-grade epoxy resin powder (EP) coatings or coatings formed by poly powder (PE) are odorless and can reach direct drinking water.
