Product Description
Title: Precision pipe rollers for safe and efficient pipe laying
Qingdao Zhaoyuqi Machinery Company manufactures high-performance pipe rollers (also known as pipeline rollers, support rollers or conveyor rollers) designed to support, guide and protect heavy pipes during construction, installation and operation. Using our advanced sand casting and shell molding lines, we produce durable roller housings and bearing housings that can withstand extreme loads, harsh weather conditions and corrosive environments.
Our pipe rollers are critical components in piping projects, industrial conveyor systems and load-bearing structures. Whether you need standard V-rollers for round pipes or custom flat rollers for square designs, our foundry guarantees consistent quality that meets API, ASTM and DIN standards. We serve large infrastructure projects throughout North America, Europe and South America, providing reliable solutions that reduce friction, prevent pipe damage and ensure operational safety.
Key features and unique performance characteristics
High Load-bearing Capacity: Made from high quality ductile iron (QT450/QT500) or cast steel (WCB/ZG270-500), our rollers are designed to support several tons of pipe weight without deformation.
Superior Wear Resistance: The casting process produces a dense microstructure. Additional heat treatment (quenching and tempering) further increases surface hardness, extending service life in abrasive environments.
Precision Machined Surfaces: Roller contact surfaces and bearing seats are CNC machined to ensure smooth rotation, minimal vibration and reduced friction against the pipe coating.
Corrosion and Weather Resistant: Available with hot-dip galvanizing, epoxy powder coating or special anti-corrosion paints for offshore, desert or chemical plant environments.
Applications and industries
Our pipe rollers are indispensable in:
Oil and Gas Pipeline Construction: Supporting pipes during welding, trenching and backfilling. Prevents damage to the coating and reduces bending stress.
Industrial Conveyor Systems: Used as rollers in bulk material conveying systems for mining, power plants and ports.
Chemical and petrochemical plants: Support of process pipeline racks and guide expansion loops.
Shipbuilding and offshore: Heavy duty support rollers for pipeline racks and structural modules in the offshore environment.
Water and sewer infrastructure: Support of large-diameter water pipes during installation.
Operating principle
Reduced friction, load distribution
Load Support: The roller body serves as a rotating support point, transferring the vertical weight of the pipe to a fixed base or structure.
Reduced Friction: When pipe moves (due to thermal expansion, construction pulling or conveyor movement), the roller rotates freely on high quality bearings, converting sliding friction into significantly less rolling friction.
Protection: The smooth machined surface of the roller prevents abrasion and impact damage to the protective coating of the pipe (eg FBE, 3LPE).
Alignment: V-shaped or angled rollers help center the pipe, preventing lateral movement and ensuring a stable position.
Customized solutions and production process
From molten metal to finished roller
Design and Engineering: Provide your drawings or load requirements. Our engineers optimize rib structure and wall thickness for maximum strength-to-weight ratio.
Tooling fabrication: CNC machined wood/resin tooling for clay-sand or shell processes, or foam models for gasification casting.
Molding: Automated molding lines ensure constant density. Controlled pouring temperature prevents shrinkage and porosity.
Heat treatment: Normalization or hardening and tempering to achieve the required mechanical properties (hardness, tensile strength).
Mechanical processing: CNC turning of the outer diameter of the roller and bearing seats; drilling mounting holes.
Assembly and Coating: Install bearings and seals (if required) and apply protective coatings (hot-dip galvanized/powder coated).
Quality control: Dimensional checking, balancing and load testing.
Quality Assurance and Certificates
ISO 9001:2015 certified: Strict quality management system at all stages of production.
Material Traceability: Full factory test certificates are provided for each batch, detailing chemical composition and mechanical properties.
Dimensional accuracy: Coordinate measuring machine inspection ensures compliance with ISO 8062 tolerances.
Non-Destructive Testing: Magnetic particle testing or ultrasonic testing is available for critical components to identify internal defects.
Load Testing: Selected roller samples are subjected to proof load testing to confirm safety factors.
Certificates:
ISO 9001:2015
CE marking (for relevant machine components)
RoHS/REACH Compliant (for coatings/materials)
(Optional) API Q1 / ISO 29001 (for specific oil and gas sectors)
Logistics, packaging and delivery
Packing:
Standard: Steel pallets with shrink film and metal tape for stability.
Heavy: Wooden boxes or special steel frames for oversized rollers.
Protection: Bearing areas are protected with oil paper and plastic plugs to prevent contamination during transportation.
Delivery terms: FOB Qingdao, CIF, DDP to the main ports of the world.
Production time:
Standard products: 15–20 days.
Individual castings: 25–35 days (depending on the complexity of the tooling and volume).
Minimum Order: Flexible. Low minimum order for trial batches; discounts for large volumes for large projects.
