Description
Foam pig pipeline are essential tools in pipeline maintenance, designed for various cleaning and processing applications. EMT offers a comprehensive range of foam pigs, including bare foam pigs, brush foam pigs, polyurethane foam pigs, brush polyurethane foam pigs, and criss-cross foam pigs. These versatile cleaning devices are popular due to their cost-effectiveness and adaptability.
1. Foam Pig Pipeline Specifications
The ends of foam pig pipeline are coated with polyurethane, providing enhanced durability, and they feature a shrink range of 3-5%. EMT manufactures foam pigs in three different densities to suit various operational needs:
- Low Density: 35 kg/m³
- Medium Density: 90 to 120 kg/m³
- High Density: 120 to 150 kg/m³
These foam pigs are specifically designed for applications such as liquid removal, drying, sweeping, and general cleaning, making them ideal for maintaining pipeline efficiency.
2. Material and Construction
EMT produces foam pig pipeline for all pipe sizes using molded polyurethane foam, available in three densities:
- Light Density: 0.02-0.03 g/cm³
- Medium Density: 0.08-0.12 g/cm³
- Heavy Density: 0.13-0.16 g/cm³
This range of densities allows for tailored solutions depending on the specific cleaning requirements of the pipeline.
3. Advantages
Foam pigs are essential for efficient and reliable pipeline maintenance, offering the following key benefits:
-
Lightweight & Flexible
Easy to handle and deploy, even in large-scale operations. Their flexibility allows passage through complex pipeline layouts including bends and reducers without requiring additional equipment. -
Superior Cleaning Performance
Effectively remove liquids, sludge, debris, and deposits from pipe walls, preventing blockages and restoring flow efficiency. Suitable for a wide range of applications across industries. -
Accurate Tracking Capability
Enable real-time location monitoring for precise cleaning progress tracking and improved maintenance planning. Ideal for ensuring complete pipeline coverage. -
Strong Drying Capacity
Light-density foam pigs offer excellent moisture absorption, significantly reducing drying time and preventing corrosion or contamination caused by residual water.
Foam pigs provide a cost-efficient and versatile solution for enhancing pipeline integrity and operational continuity.
4. Application of Foam Pig Pipeline
Foam pigs are versatile tools essential for pipeline integrity and efficiency in the oil and gas industry.
1. Liquid Unloading
Remove residual liquids (water, condensate, or hydrocarbons) to prevent blockages and maintain flow.
2. Pipeline Drying
Absorb moisture after hydrotesting or cleaning to avoid corrosion and contamination.
3. Debris & Deposit Removal
Clear solids, sludge, and wax from inner walls to ensure flow efficiency and reduce pressure loss.
4. Wax Control
Manage wax buildup in crude pipelines to maintain throughput and prevent clogging.
5. Pre-Inspection Cleaning
Clean lines prior to inspection runs to ensure accurate tool performance.
Foam pigs provide a cost-efficient solution for maintaining pipeline performance and extending service life.
