Di Flanged Pipes

We are manufacturing Flanged pipes with flanges Welded/Screwed on Ductile Iron barrel Pipes of K9 Class as per IS 8329. The flanges are rated as PN 10/PN 16, that correspond to the operating pressure values of 10 and 16 kg/cm2, respectively.

Advantages

Ductile Flanged Pipes made by us have several advantages. Some of these are:

Stronger : Ductile Iron Flanged Pipes are much stronger due to its higher tensile strength and better impact resistance.

Safer : It offers higher factor of safety against pressure fluctuations, water hammer and outside impacts.

Lighter : DI Flange Pipes are lighter, reducing handling and transportation cost Negligible breakages in transit and during handling: Does not break on sudden impacts. Loss due to transportation and handling are minimized.

Reduced pumping costs : Centrifugally Cement Mortar Lined pipes result in a smooth inside surface that also reduces friction loss.

Better casting process : Centrifugal casting of the Pipe barrel ensures compact casting and eliminates casting defects like blowholes, pinholes, slag inclusion and core displacement

Longer life and excellent corrosion resistance : Internal cement mortar lining prevents corrosion of the inside surface. The external Zinc/Bitumen coating offers extra protection against external corrosion

Dimensional accuracy and better finish:Centrifugal casting ensures uniform wall thickness and excellent surface finish. In green sand casting, uniform thickness cannot be achieved due to floating, shifting or deformation of the core.

Application

Note :Flanged Pipes are not meant for underground installation. Due to the risk of excessive bending moments being imposed, it is recommended that the flanged pipeline is Not buried
