HPVC波纹管主要用于电力电缆管 

HPVC bellows are mainly used for power cable pipes

高强度聚氯乙烯HPVC 双壁波纹管内、外壁之间呈中空环状结构,充分利用工字钢结构原理,提高截面惯性矩,环刚度高。产品具有强度高、韧性好、质地轻等优点。

The high-strength polyvinyl chloride HPVC double-wall corrugated pipe has a hollow ring structure between the inner and outer walls, making full use of the I-steel structure principle to improve the moment of inertia of the section and high ring stiffness. The product has the advantages of high strength, good toughness and light texture.

 

1、外观:管材内、外壁应光滑、平整,无气泡、裂纹、分解变色线及明显的杂质,管材断面切割应平整,无裂口、毛刺并与管轴线垂直。

2、颜色:管材内外层各自的颜色均匀一致,外层一般为本色,或由供需双方协商确定。

3、平均外径(mm):标称值:200   允许误差为:0 ~ +0.9

4、弯曲度:小于1%

5、环钢度(KN/m2):≥8

6、落锤冲击试验(%):置于温度(0±2)℃的水浴或空气浴中进行状态调节 1h,TIR≤10。

7、维卡软乎点温度(A50法)(℃):≥78

8、密度(g/cm3):1.35~1.50

 

1. Appearance: The inner and outer walls of the pipe should be smooth and flat, free of air bubbles, cracks, discoloration lines and obvious impurities, and the cross-section of the pipe should be flat, without cracks, burrs and perpendicular to the pipe axis.

2. Color: The colors of the inner and outer layers of the pipe are uniform, and the outer layer is generally the original color, or determined by the supply and demand sides.

3. Average outer diameter (mm): Nominal value: 200. Allowable error: 0 ~ +0.9

4. Bending degree: less than 1%

5. Ring steel degree (KN / m2): ≥8

6. Drop weight impact test (%): Condition adjustment in a water bath or air bath at a temperature of (0 ± 2) ℃ for 1 h, TIR≤10.

7. Vicat soft point temperature (A50 method) (℃): ≥78

8. Density (g / cm3): 1.35 ~ 1.50
