TRUFORM manufactures ductile iron pipe fittings conforming to IS 9523. These are of size 80-600 mm in diameter. These fittings are internally cement-mortar lined and on the outside are zinc coated with bitumen coat.
Our fittings go through hydrostatic test where the fittings are kept under pressure for 10 seconds to check for leakage, sweating or defect of any kind. So, what you get is a totally defect free product.
