Quality Control

Raw Material Inspection

Check raw materials before production to ensure stable product performance.

Dimensional Inspection

Check density, closed-cell structure, foaming uniformity, and surface quality.

Mechanical Performance Testing

For pipe supports, check compressive strength and project load requirements.

Anti-corrosion Inspection

For pre-insulated pipes and steel components, check coating thickness and anti-corrosion quality.

Delivery Inspection

Prepare inspection records, photos, packing list, and shipment documents before delivery.

Foam Quality Checking

Check density, closed-cell structure, foaming uniformity, and surface quality.

Packaging & Delivery

WanFu provides packaging support according to product type, quantity, shipment method, and destination country.

For Polyurethane Pipe Shells

Moisture-proof film, cartons, woven bags, pallets, compression-resistant packaging, and size labels can be used.

For Pipe Supports

Protective packaging helps reduce impact, moisture, metal part scratches, and surface damage during transportation.

For Pre-insulated Pipes:

Long pipes are loaded with proper spacing, support, and fixing to reduce movement and damage during transportation.

For Spray Foam Machines:

Machines can be packed with reinforced wooden cases to protect electrical systems, spray guns, hoses, and precision components.

Have Questions?

What production and testing equipment does WanFu have?

WanFu operates HDPE outer casing production lines, high-pressure polyurethane pouring machines, pipe threading equipment, foaming platforms, molds, and shot-blasting equipment. Our inspection facilities include spark leak detectors, tensile strength testers, coating thickness testers, and melt flow rate testers.

How does WanFu control the quality of raw materials?

All major raw materials are inspected before production. This helps maintain consistent foam performance, dimensional accuracy, mechanical strength, and overall product quality.

How is polyurethane foam quality inspected?

Our quality team checks polyurethane foam density, closed-cell structure, foaming uniformity, surface condition, and dimensional accuracy to ensure that the finished product meets project requirements.

How are polyurethane pipe supports tested?

Polyurethane pipe supports undergo dimensional and mechanical performance inspections. Their compressive strength and load-bearing capacity can also be checked according to the operating conditions and load requirements of the project.

How is the anti-corrosion quality of pre-insulated pipes checked?

For pre-insulated pipes and steel components, we inspect surface preparation, coating thickness, coating condition, and overall anti-corrosion quality before packaging and delivery.

How are products packaged for international transportation?

Packaging is selected according to the product type, quantity, shipping method, and destination. Options include moisture-proof film, cartons, woven bags, pallets, reinforced wooden cases, protective supports, and secure fixing for long pre-insulated pipes.
