Application of spiral steel pipe in the urban pipeline

Spiral steel pipe is usually used in urban drainage pipelines. The use of spiral steel pipes in urban drainage pipeline systems is the comprehensive arrangement of urban water supply, water supply, water use, drainage, sewage treatment, and other pipeline systems and their various components within a certain period. The overall balance of urban water pipeline planning is very important, and various feasible water-saving and water-delivery schemes must be optimized and combined. To this end, we must first understand the urban water use plan, strengthen the special water use plan in the urban master plan, and formulate the urban water use plan according to the concept of sustainable development of water. The content should include surface water, groundwater, rainwater and seawater, resource balance, water supply, drainage, and sewage reuse; water supply and water conservation plans and sewage treatment and recycling plans; water ecological cycle planning; various water supply and drainage pipeline engineering facilities size and layout.

For the problems of uncoordinated planning, unmatched construction, and inconsistent management in the construction of urban water supply and drainage pipeline systems in my country, special attention should be paid to the coordinated development of pipeline matching and water supply and drainage. The processing capacity in the planning and the scale of the internal water supply pipeline system and its network facilities during the planning period should be detailed in the layout and operation management plan.

The design of the spiral steel pipe in the drainage pipeline should meet the requirements of regional and urban master planning, and fully consider the scalability of the system. In the design, the ease of maintenance and overhaul of the water system should also be considered, and the pipes should be as short and efficient as possible.

The spiral steel pipe is a spiral steel pipe made of strip steel or coiled into a spiral shape, and both internal and external joints are actively welded by the double-sided submerged arc. Due to the following reasons, it can be widely used in the production of water, electricity, chemical industry, and other industries. It only needs to change the forming point of view to produce steel pipes of various diameters with the same strip width, and it is easy to adjust.

Since it is formed by continuous meandering, the length of the spiral tube is not limited, and the length can be set arbitrarily. The spiral shape of the welding seam is evenly distributed on the circumference of the spiral tube, so the spiral tube has high dimensional accuracy and strength. Easy to change scale, suitable for small batch production, and various types of spiral tubes.

Generally, the weld of the spiral steel pipe is longer than that of the straight seam steel pipe of the same standard, and the pressure on the spiral steel pipe is the same under the same standard wall thickness.

To meet the modern production requirements, the production time of the spiral steel pipe has become shorter and shorter, and the product price has become lower and lower, so the spiral steel pipe has gradually replaced the use of channel steel.
