TPP Boilers utilizes the latest techniques to expand tube ends into tube sheets for pressure and reaction vessels made from materials such as mild steel (M.S.), aluminum, Monel, Inconel, and Cupronickel. We perform rigorous high-pressure tests on heat exchangers before dispatch. Tube sheets are made from brass, copper, M.S., or stainless steel, and baffle plates from mild steel or stainless steel. We specialize in fabricating ‘U’ tube heat exchangers for fertilizer plants, petrochemical industries, and power projects, with exceptionally quick delivery, including for tubes up to 23 meters long. Our wide inventory allows us to supply tubes to any specification or length promptly. Material grades and specifications include low carbon steel (ASTM A179, DIN 17175 ST 35.8, SA 192), low alloy steel (ASTM A199/A213, T1, T11, T12, T22, T5, T9), stainless steel (304, 304 L, 321, 316, 316L, 316 T, 317, 347, 347 HF4, 310 S), and non-ferrous materials (ASTM B111, Grade 142, 122, 272, 260, 443, 687, 706, 715).
