Deflection gauges, "mandrels", are used to test flexible sewer pipes for out-of-roundness (deflection). This testing ensures flexible pipe has been properly bedded and back-filled to give optimum performance (ASTM Designation D2321-89).

Deflection gauges (mandrels) are used to test flexible sewer pipes for out-of-roundness or deflection. This testing ensures that flexible pipe has been properly bedded and backfilled to give optimal performance. Explore our complete line of fixed steel and aluminum gauges and kits.

Explore our diverse selection of pipeline deflection gauges for precise pipe deflection testing, available in a range of sizes & tolerances to meet your exact needs.

2021年12月10日 · A mandrel is a tooling component that is used during a pipe bending operation to boost its accuracy to offer incomparable performance. It is designed to tackle many bending issues, including errors and damages caused during the tube fabricating process.

2023年10月10日 · Commonly know as pigging, mandrel inspections test flexible pipes for deflection or out of roundness. The mandrel is pushed or pulled through each pipe to locate problems. A mandrel is a tool made with metal rods and fingers that will stop itself when it encounters an issue or blockage.

Mandrel Testing is an essential service for ensuring the longevity and functionality of sewer and drainage pipelines. By detecting deformations and obstructions early, it prevents costly repairs, minimizes environmental hazards, and ensures compliance with industry standards.

Choose from our selection of mandrels, including over 1,100 products in a wide range of styles and sizes. In stock and ready to ship.

2023年8月1日 · A mandrel is a supporting tool inserted into the pipe during the bending process to maintain the pipe's internal diameter and prevent deformation. By providing internal support, mandrels counteract the forces exerted on the pipe during bending, ensuring consistent and accurate results.

2022年8月1日 · Mandrel bending adds physical strength to the pipe to eliminate backpressure and pipe collapse. The solid tool inserted inside the tube or pipe is called a mandrel. Choosing the ideal mandrel is important to achieve a good mandrel bend.
