性能特点:

Performance features:

1.承压高,机械性能好: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。

1. High pressure bearing and good mechanical performance: continue the advantages of steel pipes, have high mechanical strength and have strong bearing capacity for external impacts such as impact bending etc.

2.耐化学腐蚀性能强:具有塑料管的优点,塑料涂层具有很强的耐化学腐蚀性能。产品可带法兰进行涂装,各种管件均经过内外涂塑防腐处理以确保整体管路的防腐效果。

2. Strong chemical corrosion resistance: having the advantages of plastic pipes, the plastic coating has strong chemical corrosion resistance. The products can be coated with flanges, and all kinds of pipe fittings are treated with anti-corrosion treatment on inside and outside coatings to ensure the anti-corrosion effect of the whole pipeline.

3.涂层附着力强:采用特殊工艺进行预处理,涂塑前达到Sa2.5级标准,科学合理的工艺及先进的生产设备保证了涂层质量。

3. Strong adhesion of coating: pretreatment by special process, reaching Sa2.5 standard before plastic coating, scientific and reasonable technology and advanced production equipment ensure coating quality.

4.不结垢、流体阻力小:内表面涂层精密,不结垢,摩擦系数及粗糙系数均小于普通钢管,粗糙系数与塑料管相等0.01。

4. No fouling, low fluid resistance: the inner surface coating is precise and non-fouling, thus the friction coefficient and the roughness coefficient are smaller than those of ordinary steel pipes. The roughness coefficient is equal to that of the plastic pipes, i.e. 0.01.

5.各种连接方式,便于施工:产品可采用法兰连接、快速接头连接、双金属连接及对焊连接,连接方式多样性,安装便捷。

5. Various connection methods, convenient for construction: the products can be connected by various methods, including flange connection, quick coupling connection, bimetallic connection, and butt-welding connection, which is convenient for installation.

6.内外涂层可根据客户要求采用不同涂层材料及颜色:主要涂层方式为内外聚乙烯粉末涂塑、内外环氧树脂粉末涂塑及内聚乙烯粉末外环氧树脂粉末涂塑,颜色可根据客户需求进行跟换。

6. The internal and external coatings can be coated with different coating materials and colors according to customer requirements: the main coating methods include internal and external polyethylene powder coating, internal and external epoxy resin powder coating, as well as internal polyethylene powder coating and external epoxy resin powder coating. The colors can be replaced according to customer needs.
