General Information

Lined Plastic Pipes Introduction

The lined pipe has a Mechanical bonding between pipe and line material.
By applying a lined material to a carbon steel pipe, we can get the benefit of anti-corrosion property of lined material and the strength of carbon steel.

Lined plastic pipe is a steel-plastic composite pipe, which is made of ordinary carbon steel pipe as the substrate, lined with thermoplastic pipe with excellent chemical stability, and formed by cold drawing or rotomolding, which has the mechanical properties of steel pipe, and the corrosion resistance of plastic pipe, slow scaling, and not easy to grow microorganisms.

Plastic lined steel pipe inherits the respective advantages of steel and plastic pipe, while discarding their respective shortcomings.

One of the important elements in pipe design is to reasonably determine the wall thickness of the pipe according to the use conditions and requirements, while this parameter directly affects the cost performance of the product.

Polymer Lined Steel Pipe
We can design the pipe liner according to the chemical medium and the temperature, friction coefficient of different materials. Advanced coating process and automatic equipment are applied, the plastic are meltas lining of steel pipe, this enhance the adhesion of the plastic coating and steel pipe, so that the product has good wear resistance and impact resistance.

The coating has the advantages of smooth surface, small friction coefficient, good wear resistance, non-toxic coating, no solvent, no exudation and no pollution of medium. It is suitable for pharmaceutical, beverage, food, brewing, purified water, chemical industry, mine, power industry,etc. with high requirement for sanitary conditions.

1. Excellent physical properties
2、It has good corrosion resistance
3、The mechanical strength is the same as steel pipe

Advantages of the Production Process

Our self-developed “balloon traction” and “no seam” pipe lining processes are superior to other manufacturers’ “airbag direct expansion” and “seam” processes. Seamed” process.
① “Balloon traction” process: our company independently developed a new process of pipe lining, which refers to the use of special balloon traction from one end of the pipe mouth to the other end, to drive out the gas between the rubber and the inner wall of the steel pipe, so that the rubber lining on the inner wall of the steel pipe.
When the balloon or airbag is lined with a constant air pressure, the area under pressure of the balloon is much smaller than that of the airbag, so the pressure per unit area of the rubber and steel pipe is much higher in the “balloon traction type” than in the “airbag direct expansion type”, which ensures This ensures the adhesion of the rubber to the steel pipe. After experimental comparison, the “balloon traction” process is 20-30% stronger than the “airbag direct expansion” process in terms of rubber-metal bonding strength, and the “balloon traction” process takes up less labour and is more productive. process takes up less labour and the production efficiency is twice as high as that of the “airbag direct expansion” process, which is far ahead in the rubber-lined pipeline industry.
② “No seam” process: Some manufacturers currently use the “seam” process to make rubber lined pipes. The disadvantage of this is that the seam area is easily cracked under the wash of the slurry for years and years until the rubber lined pipe is decoupled, resulting in blockage of the pipe body and affecting production. Our company introduced rubber extrusion line to extrude the whole rubber pipe, the whole lining into the steel body wall, so as to ensure the smooth inner wall of the rubber lining pipe, but also to improve the service life.
