Cast Iron Flange Pipe

With Truform's expertise and experience in screwing technology, the CI Flanges are tightened I Screwed fit on either side of C.I. Spun pipes by machines. The pipes are internally & externally coated with Bitumen paint. The flanges are generally supplied with flat face, however if required raised flanges may also be supplied. The flanges are genera), drilled as per IS:1536 & IS:1538.

Range:

• Size 80 mm to 100D mm.
• Length : up to 5. Sm. available in mix lengths and std lengths of 2. 7 5, 3, 3.5, 4, 4.5, 5, 5.25 & 5.5m.

Application :

• Water Supply - Overhead Water Tanks. Pumping stations, Underground Mains. River Crossing, Hill Tracks. Sandy area, etc.
• Vertical Pipe Lines for overhead Tanks! Elevated Service Reservoirs (ESR's).
• Treatment Plants-Portable Water. Effluent and Waste Treatment.
• For Laying in HiIIy Areas Slopes, even exceeding the Angle of Repose.
• Fire Fighting Systems
• Disengagement Requirements:
• Application where pipelines are disengaged I dismantled for cleaning like in treatment plants for water. Effluent. Sewage and pump houses.
• Temporary installations, applications where pipelines are transferred. from one location to other: require Flange Pipes like temporary pipelines required for De-Watering mines or heavily inundated areas.
• Over Ground and & Exposed Installation. Flanged Pipes are most suitable for over ground pipelines like portions of Pipelines on Pillars /Pedestals for Rivers d Canal or Road crossing and bridges.
• Ash Disposal in Power Plants.
• Sand Stowing operations in Mines.
• Cast Iron Double Flanged Pipes are widely used in Soda ASh Plants. Fertilizer Plants, SulphuricAcid Plants.
• Sugar Industries for Spray pond, SO, piping & Injection Piping.
• Chemicals Industry application for cooler pipes for conducting various chemical fluids like Sulphuric Acid, Brines. Alkalies, etc.

Advantages of Screwed flange pipes over Sand Casted pipes :

• In the manufacturing of these pipes, centrifugally casted barrel pipe is used which has a dense and homogeneous structure with superior wear resistant qualities resulting in longer life of pipes. This has been proved beyond all doubts by a study conducted by IISCO (A Govt. of India Enterprise), that the life of 150 mm dia class `B' Screwed Flange pipe is higher by 13% over sand casted pipe.
• Sand Cast pipes are available in length of 9 ft. (2.75 mtrs) whereas our Screwed Flange pipes are available in any lengths upto 5.5 mtrs. Longer lengths (100% longer means 50% of Flange joints and fast laying of pipe. This results in saving of jointing and laying cost.
• 150 mm dia Screwed Flange pipe is lighter than the sand casted pipe, which means ease of handling, while raising and fixing the pipe for overhead tanks.
• Mechanical Properties: The centrifugal casting process imparts to the screwed pipe barrel uniform sectional thickness, higher strength, high resistance to bursting and transverse stresses and ensures freedom from blow holes and homogeneity of structure.
• Being machined on sophisticated machines, highest quality of pipe is ensured. Before tightening of flanges on the barrel a suitable epoxy resin is applied on the threads ensuring leak proof joints.
• More over the centrifugally casted barrel of these pipes have smooth inner surface and hence frictional losses are minimum resulting in more discharge over the same size of sand casted pipe, whose inner surface is much more rough. This results in lower pumping costs.
• We can supply the pipe in sets of desired length for a particular height of ESR.
