The composite of each layer is carried out in a plastic melting state, and the winding tube (middle and air wall tube) is completely different from the secondary melting molding, so the layers are fully bonded and the firmness is very high. The steel belt surface is specially pre-treated to enhance the corrosion resistance of steel and the bonding force of steel and plastic, and to increase the peeling strength. In the plastic raw material smelting fully in the state of winding molding, the overall structure of the pipe is solid and reliable.
Because the use of special materials and processes not only solve the problem of corrosion corrosion of steel plate and solve the bonding degree of steel plate and PE material, so that the service life of the pipe and pure plastic pipe, guaranteed in more than 50 years. It can be used with electrothermal melt connection, heat shrink belt connection, internal and external extrusion welding or a combination of multiple connections, and the connection is secure. Reliable connections allow the pipe to reach zero leakage.
The advantages of the kla tube:

1, water conservancy conditions are good: because of the smooth surface of the internal wall of the HDPE pipe, the roughness coefficient of the pipe n-0.009, under the same pipe diameter conditions, than the steel pipe over flow 30%, that is, when transporting the same amount of sewage flow, choose HDPE pipe, its pipe diameter can be compared to the use of steel pipe to reduce 1-2 pipe grade.

2, flexibility is good: HDPE tube is a flexible tube, good extension performance, so it can adapt to the poor foundation under the conditions of construction and foundation subsidence, especially in coastal areas, the foundation is poor, the sedimentation is serious, the pipe can be greatly adapted to uneven settlement.
3, good sealing, can achieve zero penetration: because the pipe connection can use electromelt welding technology, so that the two ends of the pipe at the interface melt as a whole, to ensure that the interface will not leak.

4, light quality, easy to install: reduce the labor intensity, shorten the construction period.
