GD type vortex silent special single pipe drainage system (different layers, same layer)

GD type vortex silent special single pipe drainage system (different layers, same layer)

The GD-type vortex silent special single-pipe drainage system uses PVC resin as the main raw material, incorporating special sound-absorbing/sound-insulating materials and processing aids. It features a self-developed special spiral silent structure on the inner wall of the pipe, extruded into a one-piece silent pipe, and has been awarded an invention patent certificate by the National Intellectual Property Office (ZL200810069249.2).

PVC-U solid wall drainage pipe

PVC-U solid wall drainage pipe

PVC-U solid wall drainage pipes are made from polyvinyl chloride resin as the main raw material, with the addition of necessary additives, and are formed through extrusion processing using a twin-screw extruder. This is a mature technology for drainage pipe series products, which have been widely used both domestically and internationally. The products have advantages such as a long lifespan that is unmatched by cast iron pipes, corrosion resistance, and are also lightweight, making them easy to handle, install, and connect. They are widely used in civil construction drainage and sewage, chemical drainage and sewage, rainwater drainage, and other fields.

PVC-U hollow internal spiral drainage pipe

PVC-U hollow internal spiral drainage pipe

The PVC-U hollow inner spiral drainage pipe is primarily made from polyvinyl chloride resin, with necessary additives included, and is formed through extrusion processing. This product changes the traditional disordered method of gravity drainage into an orderly method of spiral guiding water and air through rotational inflow. This forces the water to flow along the pipe wall in a film-like manner, reducing the flow speed, decreasing the resistance coefficient of the water tongue, and lowering the noise generated by water impact on the pipe material. Research shows that the noise level of the PVC-U hollow inner spiral drainage pipe is only 30%-50% of that of ordinary PVC-U solid wall drainage pipes. At the same time, its water flow capacity has also been greatly enhanced, providing multiple benefits.

Anti-settlement HD-PE double-wall corrugated pipe

Anti-settlement HD-PE double-wall corrugated pipe

The anti-subsidence HD-PE double-wall corrugated pipe is a new type of lightweight pipe made from specially modified PE materials. It features characteristics such as light weight, high pressure resistance, good toughness, quick installation, and long service life. Its excellent "parallel" design for pipe expansion and insertion resists ground movement and subsidence, disperses external pressure, and solves stress concentration issues. Additionally, due to its convenient and reliable connections, it has been widely used both domestically and internationally, significantly replacing concrete pipes and cast iron pipes.

Anti-settlement high-strength PP-HM double-wall corrugated pipe

Anti-settlement high-strength PP-HM double-wall corrugated pipe

The anti-subsidence high-strength PP-HM double-wall corrugated pipe is a non-pressure underground drainage and sewage structural wall pipe system, featuring a smooth inner surface and a specially shaped outer surface. This type of pipe system is made from high-strength modified PP-HM resin as the base material, with the addition of special modified functional masterbatch, which enhances the product's impact resistance, rigidity, and weather resistance while ensuring stable product quality. The research team at Guodi Technology collaborates with outstanding domestic equipment manufacturers to optimize the design of the pipe's corrugated structure, making it more rational. Compared to traditional double-wall corrugated pipes, it has a higher rigidity-to-weight ratio and better cost performance; especially in challenging construction environments, such as those with collapsible soil or high backfill foundations, its advantages are even more pronounced under high anti-subsidence requirements, making it a safe and reliable choice for you.

Buried polyethylene (PE) steel belt reinforced spiral corrugated pipe

Buried polyethylene (PE) steel belt reinforced spiral corrugated pipe

Steel belt reinforced polyethylene (PE) spiral corrugated pipes are made from high-density polyethylene as the primary raw material, with a wave-shaped steel belt coated with adhesive resin as the main supporting structure. The polyethylene material is wound to form an integrated spiral corrugated pipe. In addition to having the corrosion resistance, smooth inner wall, and low flow resistance typical of ordinary plastic pipes, the product features a hollow annular structure reinforced with a steel skeleton, allowing it to meet ring stiffness requirements of SN8, SN10, SN12.5, and SN16.

Buried polyethylene (PE) spiral structured wall pipe (Krah pipe)

Buried polyethylene (PE) spiral structured wall pipe (Krah pipe)

The buried polyethylene (PE) winding structured wall pipe uses the latest hot winding forming process. Compared to directly extruded structured wall pipes, it has a higher ring stiffness (ring stiffness reaches SN16), can produce larger diameters (up to 4000mm), and has strong adaptability to uneven settlement and misalignment due to socket fusion connections. It also has good seismic resistance, is not prone to leakage, and is easy to construct.

Polyethylene (PE) trenchless drainage pipe

Polyethylene (PE) trenchless drainage pipe

Polyethylene (PE) non-excavation drainage pipes are primarily made from PE100 grade pipe material, with necessary additives added, and are formed through extrusion processing using a single-screw extruder. This product is resistant to compression, acids, alkalis, and chemical corrosion. It uses heat fusion connections, with the tensile strength of the welded joints greater than that of the body strength, and has good toughness. It is suitable for non-excavation dragging construction of rainwater and sewage collection, treatment, and discharge pipeline systems. Excavation pipes are also primarily made from PE100 grade pipe material, with necessary additives added, and are formed through extrusion processing using a single-screw extruder.
