HK Concrete Pipe Joint Testing Equipment by Straub

Straub Pipe Joint Testing Equipment

The HK Test Coupling by Straub is an external concrete pipe coupling tester that can maintain up to 50 psi/345 kPa of external joint pressure. This useful concrete pipe joint tester enables plants to test the watertightness of joints before they are shipped to an installation. The HK Test Coupling by Straub tests for infiltration, which is a more important coupling test methodology than traditional exfiltration testing. This coupling provides a simplified joint testing method to ensure that joints and gaskets will provide the watertight seal required by the job.

Pipe Coupling Tester Overview

With more than 50 years of continuous development and improvement, these pipe coupling testers are composed of premium materials and designed for easy installation, trouble-free service and a long lifespan. Our pipe joint testing equipment presents a faster, economical and more accurate way to test watertightness in the plant without damaging pipes.

Features of Our Pipe Coupling Tester

Ensure reliable results in your plant with the HK Test Coupling by Straub, a pipe coupling tester designed for fast, accurate assessments of concrete pipe joints. This advanced testing solution streamlines your quality checks while safeguarding your products from damage.

  • Quick and straightforward operation. The test coupling is easy for plant crews to set up and use, integrating seamlessly into daily quality assurance routines.
  • Replicates real-world site conditions. By applying external pressure, this testing method mirrors the stresses joints will face once installed, giving engineers confidence in their watertight performance.
  • Preserves concrete integrity. Unlike older testing methods requiring drilled holes through the bell, this coupling leaves your concrete structures undamaged during testing.
  • Uses only the primary gasket. There is no need to add a secondary gasket to achieve a proper seal, simplifying the process and saving time.
  • Built for repeated use. When properly maintained, this test coupling delivers long-lasting service for countless testing cycles.

Pipe Coupling Tester Applications

The HK Test Coupling by Straub is a trusted test coupling for industrial pipes, relied on by concrete pipe plants to confirm joint integrity before products leave the yard. It ensures concrete pipe joints and manhole connections are watertight and meet all engineering and municipal standards.

This pipe coupling tester is also ideal for checking the sealing performance of other pipes with similar outside diameters. Many plants use it for jack, microtunnel, and steel end ring pipes, giving them a versatile, dependable solution for numerous industrial joint testing needs.

Hamilton Kent’s extensive coupling range covers a variety of pipe materials and applications beyond test couplings. For concrete pipelines, the Straub Concrete Coupling offers a durable, weld-free connection. Our steel and stainless steel restraint couplings and ductile and cast iron restraint couplings provide secure axial restraint for metal pipes, while PVC restraint couplings ensure dependable joints for plastic pipelines.

For marine environments, Hamilton Kent supplies the original marine restraint coupling and flexible marine couplings built to withstand harsh offshore conditions. When axial restraint is not required, the non-axial restraint coupling offers a flexible and secure alternative. For maintenance and repairs, repair coupling clamps and flex repair couplings provide fast, effective solutions.

Pressure Rating

We design our concrete pipe coupling tester to verify manhole or pipe joints up to 50 psi/345 kPa. Note: Pressures above 30 psi/207 kPa are not recommended for manhole joint testing without approval from a licensed engineer.

Linear Misalignment

Outer diameter misalignment of 1-2% (max 0.25”/6 mm) is admissible. Larger misalignment must be rectified into angular deflection (Cardan principle). Note: If pressures higher than 50 psi are required, please contact your HK representative.
