Weld Tester & Pressure Testing Plugs

Quick Enquiry

Product Details

Welding flaws can significantly compromise structural integrity, leading to reduced performance, higher maintenance costs, or even critical failures. Our weld testing and plug solutions are engineered to ensure the safety, durability, and compliance of welded joints across industrial systems.

By applying proven inspection techniques both non-destructive and pressure-based our tools help verify weld quality efficiently, preventing long-term issues and reducing operational downtime.

Why Weld Testing is Essential

Precision in welding is crucial to maintaining the strength and safety of pipeline systems. Even small defects can result in costly failures. That’s why quality assurance through thorough testing is essential. Our weld testers support multiple inspection methods, ensuring each weld meets required standards and functions as intended in critical applications.

Common Weld Testing Methods

We support the full range of industry-approved testing approaches, including:

  • Visual Inspection: Identifies visible surface defects such as cracks, porosity, or incomplete fusion.
  • Magnetic Particle Testing: Detects surface and near-surface flaws in ferromagnetic materials through magnetization and iron powder application.
  • Dye Penetrant Testing: Highlights cracks or porosity with visible dye and developer, revealing flaws on the surface.
  • Radiographic Testing: Uses X-rays or gamma rays to detect internal weld flaws, capturing detailed images for analysis.
  • Ultrasonic Testing: Employs high-frequency sound waves to detect internal defects, with reflected signals indicating inconsistencies.

The selection of method depends on material type, defect sensitivity, and operational conditions.

Product Specification

Weld Testers

1. Internal Weld Testers

Our Internal Weld Testers are ideal for verifying welds such as flange connections or inline joints without the need to hydrotest the entire system. By isolating the weld zone, these testers reduce testing time, water usage, and disruption.

2. Dual Tools

A highly specialized tool designed for hot work upgrades, the Dual Tool enables both vapour-free isolation and pressure testing of new welds. Key features include:

  • Dual seal tires with a 6-inch annulus for double block and bleed capability

  • A venting slot for gas analysis or safe depressurization

  • Withstands up to 5 barg pressure differential

  • Available in sizes up to 36 inches

3. Flange Weld Testers

These testers offer localized pressure testing for newly installed flange welds perfect for refurbishment projects or modifications. Benefits include:

  • Focused testing without exposing the full system

  • Optional angled configurations for use on bends

  • Options for proprietary Posi-Seal or tyre-style seals to handle pipe ovality or corrosion

  • Available from 12″ to 36″, compatible with standard flange specs up to Class 2500

  • Custom options with mechanical or hydraulic actuation available

4. High-Pressure Test Plugs

Our high-pressure plugs provide safe, fast, and tool-free pipe isolation for inspection, maintenance, and repair activities.

  • Incorporates Grip-lock and Posi-Seal™ sealing technologies

  • Easy installation in any orientation

  • Widely used in oil & gas, petrochemical, and power sectors

Applications

Our range of weld testing tools and plugs are widely used in:

  • Oil & gas pipelines

  • Power plants and utilities

  • Petrochemical plants

  • Offshore and marine systems

  • Construction and infrastructure sectors
