Bridge type filter pipe is a water filtering device with bridge shaped holes. It has long been widely used in developed countries. In the 1980s, the Ministry of Geology and Mineral Resources began to introduce and promote, and achieved satisfactory results, known as the "ideal water well filter"

Mainly engaged in hydrogeological exploration, drilling, well sinking construction, reservoir dewatering, foundation deep excavation dewatering, geothermal development and utilization, mineral water development and utilization, geothermal air conditioning, repair of damaged wells, and water intake from underground water sources.
The bridge type filter pipe spiral welded pipe unit is a modification based on the original spiral welded pipe unit, adding a punch and auxiliary control system to modify the delivery and forming system. Due to the different spacing of the filter holes, the forming part is changed to an adjustable spacing type forming device to meet the needs of steel pipes. The spiral bridge type filter pipe production equipment developed by our factory has the advantages of simple structure, energy conservation, and efficiency.
1. What other uses does spiral welded pipe have in water supply engineering besides traditional oil pipelines?
Spiral welded pipes have low cost, excellent quality, and fast production speed. At present, preliminary progress has also been made in some special application directions, such as pier piling, tank welding (oil tanks, boilers, etc.), civil air defense engineering, air ducts, drums, steel structure support, pipes for high-rise building pile foundations, bridge type filter pipes, large diameter spiral circular variable square pipes, and so on. Spiral welded pipes are gradually being accepted by more and more industries due to their low cost, high level of production automation, and simple equipment structure. They will have great potential for development in the future.
2. What are the difficulties in on-site construction of spiral welded pipe equipment?
The spiral welded pipe unit can be disassembled as a whole or in sections, with a simple structure and convenient installation. Infrastructure construction can be tailored to local conditions according to on-site facilities. In the future, the spiral welded pipe unit will enter a construction site production mode, greatly reducing engineering costs.
3. What is the diameter range of spiral welded pipe equipment that can accommodate?
welded pipe equipment can be produced separately from φ 325mm to φ 3620mm, with one machine in hand, worry free production
