PE & STEEL BEND TESTING

Bend testing is performed to evaluate the flexibility, ductility, and overall quality of both polyethylene (PE) and steel pipe materials. This test involves bending a prepared sample to a specified angle to determine how well the material or welded/fused joint can withstand deformation without cracking, separating, or showing signs of structural weakness.

For PE pipe, bend testing helps confirm proper fusion procedures and verifies that the pipe or joint maintains the necessary flexibility and integrity required for long-term service.

For steel pipe, bend testing assesses weld soundness and material performance by ensuring the weld or base metal can endure bending stresses without failure.

WWNDT provides precise and reliable bend testing for both PE and steel applications, ensuring your materials meet industry expectations and project requirements for durability and safety.

PE TENSILE TESTING

Tensile testing for polyethylene (PE) pipe is used to evaluate the material’s strength, ductility, and overall performance under tensile (pulling) forces. During this test, a PE specimen often taken from pipe material or a fusion joint is pulled until it stretches and ultimately breaks. This process provides key data on tensile strength, elongation, and the material’s ability to withstand deformation without cracking or failing.

Tensile testing is a critical quality-control measure that confirms proper fusion procedures, verifies material consistency, and ensures that PE piping systems will perform safely and reliably in service. WWNDT delivers precise and dependable tensile testing to validate the integrity and long-term durability of your PE pipe and fusion joints.

PE CRUSH TESTING

A Polyethylene Crush Test is performed to evaluate the strength, durability, and structural integrity of polyethylene (PE) pipe and fusion joints under compressive loads. During this test, a section of PE material or a completed fusion joint is subjected to controlled pressure until it begins to deform. This helps verify that the pipe or joint can withstand real-world stresses without cracking, separating, or failing.

The Polyethylene Crush Test is an essential quality-control measure that confirms proper fusion techniques, material performance, and long-term reliability. WWNDT provides accurate, consistent crush testing to ensure your PE piping systems meet the required safety and performance standards before being placed into service.
