The polyurethane foam pig's length typically ranges from 1.75 to 2 times the pipe size, with a disturbance of around 25 mm or 5% to 10% of the pipe diameter. This design ensures high elasticity, strength, and notable wear resistance, with deformation capabilities exceeding 50%.

The Polyurethane Bare Foam Pig primarily consists of medium or high-density polyurethane foam as its main material. Furthermore, the base of this product is coated with polyurethane elastomer. Consequently, its primary functions include drying pipelines and effectively clearing pipeline debris.

This non-intrusive Intrusive Pig Signaller is used to determine whether the pig passes or not during pigging of oil, gas, water and other transmission pipelines.

Corrosion coupons play a vital role in detecting and assessing the corrosion condition of pipeline systems. They provide precise and reliable information about the extent of corrosion occurring within the pipelines, aiding in effective maintenance strategies. By accurately displaying the corrosion status, corrosion coupons contribute to proactive pipeline management and facilitate timely interventions to mitigate corrosion-related issues.

The Uni-directional Scraper Pig is a commonly used pig consisting of four cups and a steel frame. This pig is designed to effectively remove soft dirt and dust from pipelines. Its leather cups serve two important functions. Firstly, they provide excellent sealing performance, ensuring complete separation of liquids or gases at both ends of the pig. This creates a pressure difference that propels the pig forward. Secondly, the leather cups are capable of cleaning debris and dirt from the inner walls of the pipe.

Mechanical pig includes metal body, disc and cleaning parts. The main material of the disc is artificial rubber. It plays a guiding and sealing role. The sweeping piece is made of stainless steel wire brush or artificial rubber blade. Several bypass holes are reserved at the top of the front of the pig to control the pig’s traveling speed in the pipeline.
