Mandrel Test For Ducts

Duct proving mandrels are painted steel and are 240mm long in length with threaded steel rod and pulling eye each end to give overall length of 350mm.

Mandrel test for ducts.

Duct mandrels are necessary devices for performing duct integrity test procedure in buried telecom ducts prior blowing or installation of optical fiber cables. They will also remove small amounts of debris that may be in the conduit. Center rod is plated all thread steel. Each mandrel has a teflon body with two braided steel loop eyes on each end for versatility and strength.

Eye on each end is cast. Mandrel testing for sanitary and sewer pipes also known as deflection testing. Duct proving mandrels are manufactured from polypropylene and are fitted with steel rotating fixing eyes at each end. Suitable for use in heavy duty professional such as telecom gas and water utilities.

Sm43 steel mandrel 43mm o d. All mandrels are made to order and as a rule the diameter should be 10 smaller than the duct and the length is 1 5 times the diameter the standard sizes listed are maximum values and can be machined to your requirements. Mandrels are used to prove the integrity of installed conduit runs. Independent pipeline inspection companies complete the tests.

Sm70 steel mandrel. Cities counties and states use a mandrel to inspect the inside of underground pines and sewer conduits generally after new construction or during maintenance. Is used to determine that the ovality of the sewer pipe meets its specification. Manufactured from high strength aluminum alloy tube.

The mandrel is pulled through the conduit to insure and verify that there is an adequate clearance. Working directly with the electrical contracting electrical utility telecom and catv industries condux offers the highest quality tools engineered to reduce installation time and increase safety. Duct integrity proving mandrel are pulled through the duct to prove joint integrity and test duct integrity for round duct conduit or interdict used in telecom gas water networks. Also known as pigging mandrel inspections test flexible pipes for.

Condux international has been manufacturing cable installation tools and equipment for over 30 years. Duct integrity proving mandrel are pulled through duct to prove joint integrity and test duct integrity for round duct conduit or interdict used in telecom gas water networks.
