Product Overview

Product general introduction

The wear-resistant pipeline products independently developed and produced by Haiwang include ceramic lined wear-resistant pipeline, rubber lined wear-resistant pipeline, rubber composite wear-resistant flexible pipe and polyurethane lined wear-resistant pipeline. Different series products can be selected according to the requirements of specific operating conditions, with excellent wear resistance, long lifespan and low cost.

1. Ceramic Lined Wear Resistant Pipeline

Ceramic lined wear-resistant pipeline combines the advantages of rigidity and wear resistance. The outer steel pipe has extremely high toughness and strong impact resistance; the high strength inner high-aluminum ceramics has strong wear resistance, smooth & hard surface and scratch resistance.

Product Description

Ceramic lined wear-resistant pipelines are essentially different from traditional steel pipelines, wear-resistant alloy cast steel pipelines, cast stone pipelines, steel plastics, and steel rubber pipelines. The inner and outer two layers of ceramic lined pipeline are made of different properties, the outer layer is steel pipe, and the inner layer is high alumina ceramic, of which the wear resistance is more than 20 times higher than that of carbon steel tube.

Technical feature

• Good abrasion resistance: the Rockwell hardness of lined ceramic can reach to 80 ~ 90HRA, the surface is smooth, thus the operation resistance is small, and it has high abrasion resistance to the materials and media transported in mining, coal, metallurgy, electric power and other industries;
• Corrosion resistance, not easy to scale: as the wear-resistant ceramic is of neutral characteristics, so it has acid-base resistance, seawater corrosion resistance and is not easy to scale;
• The installation and construction are convenient: the product is light in weight, and has good comprehensive performance such as heat resistance and mechanical impact resistance. Welding, flange rapid connection and other connection methods can be used. The construction and installation are convenient, which can reduce installation costs.

Application

Mining industry: raw ore, concentrate, middling, tailings and other slurry transportation;
Coal industry: raw coal, clean coal, middling, gangue, coarse coal slime, tailing coal slime and other slurry transportation;
Metallurgy, electric power industry: transmission of pulverized coal, ash, mud, gypsum slurry and so on.

2. Rubber Lined Wear Resistant Pipeline

Product general introduction

Rubber-lined wear-resistant pipeline has the dual advantages of steel pipe and rubber material. The outer steel pipe has extremely high toughness and impact resistance. The inner HELICON wear-resistant rubber plate is formed in one body, with smooth surface, strong wear resistance and good corrosion resistance.

Rubber-lined wear-resistant pipeline is a kind of pipeline with steel or hard structure as pipeline skeleton and HELICON rubber with excellent wear resistance, corrosion resistance and high temperature resistance as liner. It adopts high performance adhesive through special process and has dual advantages of steel and rubber materials. With the physical and chemical properties of rubber, the wear and corrosion of pipeline delivered medium to the external structure are reduced, which greatly prolongs the service life of pipeline and reduces the maintenance cost of users.

 Technical Features

• Excellent structure: high bond strength of rubber and metal, combine the characteristics of metal and rubber to form a rigid and flexible composite pipeline, with the common advantages of steel pipe and wear-resistant rubber;
• Low engineering cost: the rubber elastomer with low density and light weight has no creep and is easy to transport, install and maintain;
• Energy-saving: the good lubricity and small loss of operating resistance can save operating costs;
• Stable performance: the pipeline connection with sealing function is pressure safe and reliable, suitable for long-distance high-pressure transportation.

Application：It can be used to transport abrasive slurry in mining, coal, metallurgy, environmental protection, construction, petroleum and other industries.

3.Rubber Composite Wear Resistant Flexible Pipe

Rubber composite flexible pipe has good stretching and bending performance, high flexibility in the process of on-site construction and installation, thus reduce the difficulty of construction; the connection mode of rubber composite flexible pipe include fixed flange, rotating flange, clamp or customized connection mode from the site, which can meet the connection needs of different sites.

Rubber composite flexible pipe is composed of rubber, steel wire skeleton, nylon, polyester fiber and other non-metal reinforced layers through special technology. The innermost layer is HELICON rubber wear-resistant layer, which is made of high-quality natural rubber emulsion treated with nano-formula and produced by liquid phase process, and can resist the abrasion of slurry.

Technical Features

• Strong winding performance and impact resistance;
• Abrasion resistance and corrosion resistance;
• High resistance to static pressure and tensile strength;
• Anti-aging and energy saving, easy to install.

Application:

It can be used to transport abrasive slurry in metal, non-metal mining, coal mining, and metallurgical as well as environmental protection industries. It can be used in the construction site with complex pipeline layout to reduce the number of elbows used.

4. Polyurethane Wear Resistant Pipeline

Wear-resistant polyurethane pipeline is of integrated design with smooth surface, good pressure resistance, light weight and easy to disassemble and assemble; the use of low-temperature prepolymerization and high-temperature extraction process can achieve personalized design of product formula. The product molding has good adaptability and economic efficiency.

The polyurethane wear-resistant pipeline developed and produced by Haiwang Company is a kind of pipeline with steel or hard structure as pipeline skeleton outside and polyurethane with excellent wear resistance, corrosion resistance and high temperature resistance as liner. It adopts high performance adhesive through special process and has dual advantages of steel pipe and rubber material.

Technical Features

• Resistance to sliding and impact wearing. The internal structure of polyurethane of macromolecular chain makes the inner lining of pipeline stiff and soft, and meets the demand of wear resistance to the maximum extent;

• The pipe wall is bright and lubricated with low friction coefficient, small operation resistance and anti-scaling, which can greatly reduce the energy consumption of material transportation, and avoid the scaling & blocking accident occurring in the long-term operation;

• Good at aging resistance, oil resistance and drug resistance. The lined polyurethane elastomer is a kind of strong polar polymer material, which has better resistance to some non-polar oils and other weak polar chemicals.

 Application:It can be used to make cyclone, screen plate, screen mesh, rubber roller, elastic coupling, buffer spring and other products. The products can be widely used in mining, chemical industry, environmental protection and other industries at home and abroad.
