For pressure vessels and reaction vessels in M.S., Al, Monel, Inconel, Cupronickel, etc., We employs the latest techniques for expanding tube ends into tube sheets. High pressure tests are always carried out on these heat exchangers before they leave the factory. Brass, copper, M.S. and S.S. tube sheets are used. Tube sheets are also made out of mild steel, alloy steel or stainless steel and baffle plates are made out of mild steel or stainless steel. we fabricates 'U' Tube heat exchangers which are used in fertilizer plants, petrochemical and power project complexes.
Fabrication of U-Tubes for Heat-Exchangers Spans at extremely Short Delivery time, even Extra long (23 mts.) is our specialty. Tube Bending as per TEMA. Tubes to any specification and any length can be supplied in extremely short time due to our wide Mother Tube Stocks.
These Seamless Tube mainly find applications in Pressure Vessels, Cryogenic Pressure Vessels, High pressure Equipments, Tube Sheets of Heat Exchangers, Boilers, Air Pre Heater, Finned Tubes, Air Cooler Tubes, etc. They are used in Industries like Refineries, Power Plants, Steel Plants, Chemical Factories, Fertilizer plants, and Ship Building etc.
U Tubes are manufactured after the Straight Tubes are manufactured. The Bending is done in Cold State on an Automatic U Bending Machine. To ensure that wall thinning and diameter ovality are kept in control, bending of tubes Is done with a mandrel inserted in the tubes. Furthermore the U - Bend portion of the U-Tube is Stress Relieved in controlled conditions and cycle to give longer life.
The U bent tubes are finally 100% Tested for Hydrostatic Leak Test and then finally DP tested. These tubes are vulnerable to getting damaged in transit and hence are required to be handled with care. We ensure this by packing tubes in specially designed steel frames. These frames are fit into the wooden box o further ensure safety of the tubes.
These HEAT EXCHANGER TUBES mainly find applications in Pressure Vessels, Cryogenic pressure Vessels, High pressure Equipments, Tube sheets of HEAT Exchangers, Boilers, Air Pre Heater, Finned Tubes, Air Cooler Tubes, etc. They are used in lndustries like Refineries, Power Plants, Steel Plants, Chemical Factories, Fertilizer plants, and Ship Building etc.
Theses Seamless Tube can be manufactured in Straight Lengths or U Bent As per the customer Requirements.
Our tubes are manufactured by the Cold Drawn Process (Drawn on Mandrel) to provide the closest dimensional tolerance and smooth Outside and Inside Finish. Further to achieve the desired Mechanical Properties the tubes are Heat Treated ( Normalized , Stress Relieved , Annealed , Tempered Etc ) as per the customer / Grade requirement. Straightening is done on Multiple Roll Straightening Machines to achieve accuracy up 1mm: 1000mm Straightness. Our stringent Quality checks and Best Packing practices (For Exports Special 4 Layer Packing) ensure that the material delivered to the customer is of the highest quality and reaches the destination in best condition.
