Polyethylene Pipe (SRPP)
Machinery Line System
The composite pipe has been widely used in many fields. Continuous Steel Ribbed Polyethylene Pipe (SRPP) has specific advantages of corrosion resistance, anti-settling, long service life, convenient transportation and construction installation with lower costs.
By Comparing with traditional steel wired reinforced composite pipe, this brand new composite pipe machinery technology supported by US national standards, with nearly 30 to 40 years of experience in the United States. Under Analysis and verification of the quality & service life for this kind of pipe. the pipe service life can be reached 80 years.
SRPP pipe has saved the plastic consumption nearly in 50% by comparing with other plastic sewage pipes in same diameter and ring stiffness
Pipe Service Life
Combined chemical and mechanical attachment system provide added assurance of composite integrity.
Production Line Features
Since it uses polyethylene raw material is not high, similar with the steel wired pipe, Saving at least 30-50% more by comparing with Carat Pipe. Faster composite pipe machinery production speed under lower costs, higher automation degree that makes the employment cost lower.
Lower Manufacturing Cost
The composite pipe machinery can be pulled to the site for production if meet required environment condition, which reducing the pipe transportation cost. There is no need to change the mold to manufacture any diameters between 600mm – 3000mm. Compared with the double wall bellows, steel wired reinforced pipes and Carat pipes, the production efficiencies are well considered since there’s no need to temporally pause the machine in order to change the mold.
Lower Composite Pipe Machinery Cost
SRPP has convinent production procedure, one equipment can produce 600mm+ Pipe caliber. If modified to one equipment with three sets of devices that can produce any specification pipes between 600mm – 3000mm caliber.
Lower Transportation Cost
All equipment can be assembled in a flatbed truck, which means SRPP can be produced on the truck. It saves a lot of costs for large-caliber pipe transportation.
Steel Ribbed PE pipes are perfectly combining mechanical and chemical system to ensure composite integrity by using high tightness of the cover layer，better weathering and impact resistance, strong corrosion-resistance polymeric membranes to ensure safety and be ready for long-term operation.
Production Line Advantages
DN 600 - DN 3000
Banline SRPP composite pipe machinery can produce pipe diameter from 600 mm (24-inch) up to 3000 mm (118-inch). The specific advantage is the high stiffness with lower cost. The ring stiffness reached SN8 to SN12.5 , which is higher than other typical type of pipes.
Lower Manufacture Cost
The equipment can be pulled to the site for production if meet required environment condition.
Equipment Cost Savings
one equipment can produce 600mm+ Pipe caliber.
Lower Transportation Cost
All equipment can be assembled in a flatbed truck,which allows manufacture at the field

Firstly, the galvanized steel sheet un-coiled through the coating equipment, where the outer surface of the steel sheet coil is compounded with a 0.25mm thickness protective polymer film, which is a coating film with high corrosion resistance, strength and wears resistance.
The inner surface of the steel band compounded with a 0.25 mm thickness adhesive layer film.
Then, the steel band coiled with the polymer is sent to the pipe forming machine to be processed into a pipe, and then, lined with polyethylene.
The lining material is extruded into the ribs and onto the inner pipe wall to form a 1.65mm thickness sheet.
Extruded polyethylene and the adhesive layer film chemically bond to form a 1.91 mm thickness inner liner.
