Goldstone Reinforced Polyethylene Pipe Extrusion Line SRTP for Water Supply 01

Product catalog summary

Introduction to Goldstone Reinforce Pipe Technology
Goldstone's Steel Wire Reinforced Polyethylene (SRTP/SRPE) pipe technology enhances the strength and durability of polyethylene pipes by incorporating high-strength steel cords in the middle layer. This composite structure not only improves pressure resistance but also reduces material costs.

Composite Structure and Materials
The pipes are constructed with two or four layers of steel cords wrapped around a polyethylene core. Adhesive resin fills the space between the steel mesh and polyethylene, creating a stable mesh structure. The steel-reinforced layer is then covered with a thin polyethylene layer. The tensile strength of the steel cord ranges from 1800 to 2100 MPa, significantly higher than that of polyethylene, resulting in a 130% increase in burst pressure compared to HDPE-only pipes. Alternative reinforcement materials include fiberglass and polyester fiber.

Material Cost Savings
The SRTP pipes offer substantial material cost savings compared to PE100 pipes. The wall thickness of SRTP pipes is reduced by up to 48%, and the weight is reduced by up to 40%, particularly in larger diameters such as DN630. The cost savings are further enhanced as the steel cord material is less than half the price of HDPE, leading to over 40% savings in total pipe material costs.

Comparison of SRTP and HDPE Pipes
The document provides a detailed comparison of wall thickness and weight between SRTP and HDPE pipes across various diameters (DN). For instance, a DN160 SRTP pipe has a wall thickness of 7.2 mm and weighs 3.6 kg/m, whereas a comparable HDPE pipe has a wall thickness of 9.5 mm and weighs 4.52 kg/m.

Conclusion
Goldstone's SRTP technology offers a significant advancement in pipe manufacturing by enhancing strength and reducing costs. This makes it a viable alternative to traditional HDPE pipes, especially in applications requiring high pressure resistance and cost efficiency.

Goldstone Reinforced Polyethylene Pipe Extrusion Line SRTP for Water Supply 01-1

Goldstone SRTP / SRPE Steel Wire Reinforced Polyethylene Pipe Technology Using the wire wrapping technology, the polyethylene pipe has been reinforced by high strength steel cord in the middle layer. The composite structure results the pipe materials saving and pressure improving. The new technology can make the HDPE pipe stronger, durable and in the mean time reduce the material cost definitely. Two layers or four layers of steel cords are wrapped on the polyethylene core pipe. And the adhesive resin is filled in the space between the steel mesh and polyethylene; bond them to form a stable mesh structure. Then the steel reinforced layer is covered by a thin layer of polyethylene. The tensile strength of used steel cord is from 1800 to 2100 MPa which is much higher than polyethylene, so when compared with the pipes which use HDPE only, this composite structure pipe can increase averagely 130% of the burst pressure. Steel wire, fiberglass, polyester fiber or other kinds of high stiffness fiber could be used as the reinforcement material on the polyethylene pipe. Goldstone Reinforce Pipe Technology

Material Cost Saving SRTP vs PE100 Pipe Wall Thickness PN10 SDR 17 70 60 The wall thickness ratio between SRTP and HDPE is from 0.52 to 0.75, the maximum wall thickness reduce is 48%. SRTP vs PE100 Pipe Weight PN10 SDR 17 200 180 160 The pipe total weight difference ratio between SRTP and HDPE is from 0.6 to 0.8, the maximum weight reducing is 40% which is happened on DN630 pipe. And pipe DN710 to DN1000 also has more than 30% weight reducing. For SRTP pipe, the total weight include the HDPE and Steel cord. Because the price of steel cord raw material is less than half of the HDPE price, so the...
