Description

Technical Field

[0001] This utility model relates to the field of water circulation pipeline technology, and more specifically, to a seamless steel pipe for water circulation. Background Technology

[0002] Circulating water pipelines largely use concrete or steel pipes. Concrete pipes have poor resistance to internal pressure, and steel pipes have poor corrosion resistance. Especially after a period of use, concrete pipes are prone to bursting; steel pipes are easily corroded and leak, severely impacting water supply. To solve this problem, fiberglass pipes were developed. Fiberglass pipes, with their unique advantages such as strong corrosion resistance, smooth inner surface, low energy consumption during transport, long service life (over 50 years), convenient transportation and installation, low maintenance costs, and low overall cost, have been widely used in industries such as petroleum, power, chemical, papermaking, urban water supply and drainage, factory wastewater treatment, seawater desalination, and gas transmission.

[0003] For example, the water circulation seamless steel pipe disclosed in prior art disclosure number (CN211083137U) uses a support assembly fixedly installed between an inner pipe and an outer pipe arranged coaxially. Several support assemblies are evenly distributed around the central axis of the outer pipe. The support assembly includes a support plate, one end of which is fixedly installed on the outer pipe, and the other end is fixedly installed with a fixed support plate. The supporting surface of the fixed support plate is an arc surface. The outer circumferential surface of the inner pipe is in contact with the supporting surface of the fixed support plate. Thus, the supporting surfaces of several fixed support plates are located on the same circumference, which is coaxial with the outer pipe and has the same radius as the outer circle of the inner pipe.

[0004] When the above-mentioned device is in use, the inner tube of the fiberglass pipe is prone to bumps and collisions during hoisting and transportation, and the inner tube is prone to displacement inside the outer tube, which will affect its installation. Utility Model Content
