Heat Exchangers
For pressure vessels and reaction vessels in M.S., Al, Monel, Inconel, Cupronickel, etc., TPP BOILERS 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. Tube Weld 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 TPP BOILERS 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.
