U Bends

We at NFTPL offer a vide range of U Bends which are rigorously checked by our team of talented professionals at every stage of production to deliver the clients defect free, ripple free smooth bends. 

Type of checks done - 

• 'U' bending is done by cold working process.
• The bend portion and six inch leg is stress relieved by resistance heating.
• Inert gas (Argon) is passed through it at the required flow rate to avoid oxidation in ID.
• The radius is checked for its OD and wall thinning with the recommended specification.
• The physical properties and micro-structure is checked at three different position.
• Visual inspection for waviness and cracks is done with Dye Penetrant Test.
• Each tube is then hydro tested at the recommended pressure to check for leakage.
