At present, urban sewage pipelines are being renovated across the country, and cement pipes are slowly replaced by HDPE steel strip pipes. The steel belt pipe has strong water working capacity, large total flow, smooth inner cavity, and water working capacity is 40% higher than that of other pipelines. Today, Xiaobian will introduce to you what are the advantages of steel belt pipes!

The steel belt pipe is anti-corrosion, has a long service life, is not easy to promote the growth and development of algae plants and bacteria, and can be recycled for up to 50 years. It is not easy to leak and avoid environmental pollution. The water tightness of the steel strip pipe is very good. Choose the capacitor connection belt, the integrity is very good, it is not easy to leak, and avoid sewage pollution.

The shape of the strip pipe, the strip cuts at both ends of the pipe must be on the same vertical line of the pipe. The inner surface of the pipe should be smooth, the outer waveform should be neat, the inner wall of the pipe should not have foam and visible impurities, the weld should not be disengaged, and the cross-section of the HDPE steel belt reinforced spiral corrugated pipe should be transformed into a hairless state after laser cutting.

Advantages of steel strip pipes:

1. The structure is different. The internal and external pressure compressive strength is high, the impact is strong, the ring is flexible, the inner cavity is smooth, the friction is less, and the pipe with the same inner diameter can be changed according to the larger total flow.

2. Wide usable temperature range, the pipeline will not break in the environment of -60 degrees, and the maximum temperature of the transported materials is 60 degrees.

3. The comprehensive project budget is basically similar to that of concrete, and the operating cost is low.

Common problems of steel strip pipe assembly:

Many construction companies use excavators to bury the layer of soil mixed with construction waste in the cave after laying pipes during customs clearance. It was wrong to do that and caused a lot of damage to the pipeline, and here's the right thing to do.

In the first stage, the raw material of HDPE steel strip reinforced spiral bellows is very light, and the pipe should be prevented from floating during construction.

Secondly, the steel strip pipe should improve the density of the spiral bellows mat and backfill to determine the load working capacity of the "pipe and soil" system and the radial strain rate of the pipeline, and ensure the actual effect of "pipe-soil mutual efficiency", and the density of the pipeline mat and backfill must be ensured to consider the design regulations.

Therefore, in order to ensure the above two items, there must be no water in the tank when backfilling, no backfill with water, no backfill with sludge, organic compounds, and no stones, bricks and other hard objects in the backfill. In areas with high groundwater, groundwater levels must be kept to a minimum, and groundwater reductions must be stopped when the project is not disturbed by groundwater or the basic compressive strength and pipeline navigation are not taken into account.
