Specification Analysis

CAD & CAD Modeling

Formulation & Casting

Quality Verification

We analyze pipeline geometry, fluid chemistry, and operating temperatures to determine the optimal polyurethane formulation.

Our engineers draft precise custom molds, performing reverse engineering for obsolete or imported OEM pipeline components.

We formulate raw elastomers in-house, casting foam pigs and sealing discs to exact shore hardness tolerances.

Every batch undergoes rigorous physical testing, verifying dimensional accuracy and tear resistance before dispatch.

On-Site Expertise

Direct technical consultation

In-Field Analysis

We measure pipeline geometry and fluid dynamics to calibrate custom elastomer durometers on-site.

Our engineers deploy directly to your facility or pipeline site, conducting operational reviews to diagnose premature wear and optimize pigging run performance.
