We are a China's manufacturer of customized urethane cleaning pigs for pipeline, by using a high-performance custom casting polyurethane blend. They care designed as a solid one piece structure, and have a combination of cups and discs spaced along the body.
Our solid cast urethane pipeline cleaning pigs outperform rubber ones. They keep shape under pressure, clean debris (rust, scale, sludge) effectively, and won’t degrade in oil, gas, or water pipelines. Each pig is inspected for quality before shipping.
These pipeline pigs serve oil & gas, water treatment, chemical processing, and petrochemical industries. They pay important roles in maintaining pipeline flow and preventing blockages.

Case Studies: How Polyurethane Pipeline Cleaning Pigs Solved Client Challenges
An African oil and gas client suffered frequent pig damage and short service life. After using our cast polyurethane pipeline cleaning pigs, cleaning efficiency improved by 60%, replacement frequency dropped sharply, and annual maintenance costs were greatly reduced.
A European chemical client needed special pigs for corrosive media. We provided custom polyether PU pigs with strong chemical resistance. The pigs ran stably for over 12 months without cracking or deformation.
Selection Guide of Polyurethane Pipeline Cleaning Pigs
Choosing the correct pipeline pig depends on several technical factors.
1. Pipeline Diameter and Length Large pipelines or long transmission distances require pigs with higher wear resistance and stronger sealing capability.
2. Cleaning Purpose
Dewatering → low or medium density foam pigs
Heavy scale removal → solid cast polyurethane pigs
Batch separation → cup or disc pigs
3. Pipeline Structure Pipelines with many bends, valves, or diameter changes require flexible pigs with strong deformation ability.
4. Operating Pressure and Temperature High-pressure oil pipelines require pigs with reinforced polyurethane materials and optimized hardness parameters.
5. Pig Tracking and Monitoring Long pipelines may require transmitter cavities or magnets for accurate pig tracking.
Selecting the correct pig design can significantly improve pipeline cleaning efficiency, operational safety, and overall maintenance ranking of pipeline systems.
Why are pipe cleaners called pigs?
As they moved through metal pipelines, the friction between the straw/leather and pipe walls, or the tool’s vibration against the pipe, created a loud, high-pitched noise that sounded like a pig squealing
What is a urethane process pig?
A urethane process pig is a specialized, durable tool made from high-performance polyurethane (urethane) used to maintain, test, or optimize pipeline operations—going beyond basic cleaning to support core industrial processes.
What is the difference between foam pigs and solid cast cleaning pigs?
Foam pigs are lightweight, flexible, and ideal for light wiping, drying, and navigating tight bends. Solid cast pigs (cup or disc type) are more durable and aggressive, suitable for heavy cleaning, wax removal, and long-distance runs
How do I know what density or hardness I need for my polyurethane pig?
Low-density foam (16-32 kg/m³) is best for drying and light wiping. Medium-density (80-96 kg/m³) suits general cleaning and dewatering. High-density foam (130-160 kg/m³) or solid cast (80A-95A Shore) is for aggressive cleaning of hard deposits . Contact us with your application details for a specific recommendation.
Can you provide pigs that match my OEM part numbers and specifications?
Yes. As a manufacturer, we specialize in reverse engineering and custom production. If you provide us with a sample, drawing, or detailed parameters (size, density, configuration), we can manufacture pigs that are dimensionally and functionally equivalent to your original parts
Are you a manufacturer?
Yes. We are manufacturer. Welcome to visit our factory.
Can you introduce your customized process ?
Yes. The process includes Share needs → design & quote → prototype (opt) → production → delivery.
How do you control your product quality?
We have 10 inspectors to carry out raw material inspection, process control ,first article inspection and final inspection.
How do you monitor the production process to avoid delayed delivery?
We use the ERP system to execute orders, and can check the order status and expected delivery time at any time.
What is warranty of products?
All of products with 3-6 months guarantee (except very frequently wearing parts).
How do you deal with after sales service?
We will response in 24 hours with solutions such as replacement or reworking.
How do you deal wtih customers' molds?
We have dedicated personnel to sort out and maintain molds regularly.
What about the lifespan of molds?
20,000 times for compressions molds and 30,000 time for casting molds
How long can you keep customers' molds for free?
Due to the large quantity of molds, we can keep the molds for free for 2 to 3 years even if no order.
If the molds are damaged or reach the lifespan , who will be responsible for it ?
Customers only need to pay mold cost once. We will cover the cost if molds are damaged or reach the lifespan.
