Description

1.Product Introduction

The PE abrasion-resistant pipe is a pipeline product specifically engineered for high-wear operating conditions.It is primarily manufactured using polyolefin wear-resistant materials or Ultra-High Molecular Weight Polyethylene (UHMW-PE). Through special composite processes (such as co-extrusion or three-layer composite), the pipe’s inner wall forms an exceptional wear-resistant layer. This layer effectively withstands long-term impact, abrasion, and corrosion from the conveyed medium, significantly extending the service life while reducing replacement frequency and overall costs.

Within this category, the Ultra-High Molecular Weight Polyethylene Composite Pipe (UHMW-PE) represents a premium segment of the PE abrasion-resistant pipe family. It typically features a composite structure comprising an outer steel pipe, a middle reinforcement layer, and an inner liner made of UHMW-PE pipe. This design ingeniously combines the strength of steel with the outstanding abrasion resistance of UHMW-PE, making it particularly suitable for demanding industrial environments.

3.Connection Methods

  1. Flanged Connection:This is the most commonly used connection method for UHMW-PE composite pipes. It offers easy disassembly and installation, facilitates maintenance, and helps reduce installation and repair costs.
  1. Heat Fusion Connection:This category includes butt fusion and socket fusion.
  • Butt Fusionis suitable for pipes with larger diameters. It involves heating the pipe ends to a molten state (typically 200-220°C) and joining them under pressure, creating a high-strength weld seam whose strength can even exceed that of the pipe material itself.
  • Socket Fusionis more suitable for small-diameter pipes (generally below DN63 mm).
  1. Socket and Spigot Connection:For non-pressure PE pipes, a socket and spigot connection with an elastomeric seal ring can be used. This method offers simple installation and good sealing performance.
  • Important Note:UHMW-PE composite pipes cannot be connected using welding methods.

4.Key Advantages & Selling Points

  • Exceptional Wear Resistance:Offers 4 to 7 times the abrasion resistance of carbon steel, significantly extending the service life of pipelines conveying abrasive media such as mineral slurries and ash.
  • Excellent Corrosion Resistance:Resists erosion from a wide range of chemicals, eliminating the need for special anti-corrosion treatments.
  • Good Self-Lubrication and Non-Stick Properties:Features a smooth inner wall with an extremely low coefficient of friction, minimizing scaling and reducing flow resistance.
  • High Impact Resistance:Possesses strong impact strength, effectively withstanding external physical shocks.
  • Broad Operating Temperature Range:Excellent low-temperature resistance allows for stable operation in environments from -269°C to +80°C.
  • Easy Installation:Utilizes connection methods like flanges, making installation, disassembly, and maintenance straightforward.
  • Cost-Effectiveness:Although the initial investment may be higher, the exceptionally long service life and low maintenance costs result in outstanding overall economic benefits. In some applications, the comprehensive benefits can be up to 6 times that of steel pipes. Additionally, the outer steel pipe of UHMW-PE composite pipes can be repaired and reused, providing further cost savings.

5.Product Applications

  • Mining & Metallurgy:For conveying mineral slurry, concentrates, tailings, and metallurgical waste slag. Traditional steel pipes suffer rapid abrasion in such applications, typically resulting in a short service life of only 1-2 years.
  • Coal Industry:For conveying highly abrasive and corrosive media such as coal slurry and raw ore.
  • Thermal Power Plants:For conveying fly ash and ash slurry. Steel pipes experience severe abrasion in this service, with wear rates reaching 50-60 mm per year.
  • Dredging Projects:For conveying silt from ports, rivers, and lakes. Traditional steel pipes are prone to scaling, leading to high cleaning and maintenance costs.
  • Petroleum & Chemical Industries:For conveying corrosive media like crude oil wastewater and acid solutions. Steel pipes corrode rapidly in these environments, often becoming unusable after only 1-3 years.
  • Building Materials & Grain Industries:For conveying materials such as sand, cement, and grains. Traditional pipes wear quickly; for example, seamless steel pipes used for cement transport may last only about 3 months.

6.Testing & Certifications

  • Material Performance Certification:Products are tested in accordance with relevant national or industry standards to ensure material properties (such as density, melt flow rate, oxidation induction time, etc.) meet specifications.
  • Safety Certifications:Some products can obtain specific industry safety certifications, such as Mining Safety Certification.
  • Quality Management System:Reputable manufacturers are typically certified under the ISO9001 Quality Management System.

7.Manufacturing Process Flow

  1. Co-extrusion Composite Molding:This process is used for Zhongcai PE abrasion-resistant pipes. The polyolefin wear-resistant material, serving as the wear-resistant layer, is co-extruded and integrally formed with the base pipe in a single-step operation.
  1. Three-Layer Composite Process:The Ultra-High Molecular Weight Polyethylene (UHMW-PE) composite pipe employs a three-layer structure:
  • Inner Liner:A UHMW-PE pipe providing the core wear and corrosion resistance.
  • Reinforcement Layer:A middle layer that works in synergy with the inner liner.
  • Outer Layer:A steel pipe primarily responsible for bearing mechanical pressure and providing protection.
  1. Raw Materials & Key Process Stages:
  • The primary raw material is polyethylene (PE) resin. For UHMW-PE pipes, ultra-high molecular weight polyethylene with a weight-average molecular weight exceeding 1.5 million is used.
  • Key stages include extrusion molding and cooling/solidification.

8. Packaging and Delivery

  • Packaging Method:Pipe ends are protectively packaged to prevent impact damage during transportation and storage. For Ultra-High Molecular Weight Polyethylene (UHMW-PE) composite pipes, special attention is given to protecting the flange connection surfaces and the inner liner.
  • Delivery Capacity:Products support customized lengths. For example, UHMW-PE composite pipes can be supplied in standard lengths of 6 m to 12 m as required. Manufacturers arrange production plans according to order specifications to ensure on-time delivery.

9. Sales Service

  • Pre-Sales Service:Provide technical consultation, working condition analysis, and product selection guidance to ensure the most suitable pipeline product is chosen.
