Sigma can supply with complete range of full piping system in SS 304 and SS 316 Lined Pipes & Fittings, we also offer PFA lined stainless steel ball valves, stainless steel poppet check valves and sight glasses. We manufacture piping system with all wetted parts PTFE / PFA and steel external finish of stainless steel. Corrosion performance of the stainless steel is well known, hence spending 20 % to 25 % cost on painting lines can be saved besides life of the systems is incresed consideraly if it is to be used for the longer time.

PTFE Structured Packing refers to a range of specially designed materials for use in absorption and distillation columns and chemical reactions. PTFE Structured Packing typically consist of thin corrugated . PTFE sheets arranged in a way that they force fluids to take complicated paths through the column, thereby creating a large surface area for the contact between different phases. PTFE being hydrophobic in nature and treated rough surface is necessary to achieve a good separation efficiency . It is possible to achieve 2.5 or more theoritical stages per meter of column height by our PTFE structure packing. Advantages   It is completely chemically inert material It is strong but light in weight. It gives rise to adequate passages for both Gas & Liquid streams without excessive liquid hold up or pressure drop. It provides a good contact between liquid and gas. It is washable and reusable. It is unbreakable too. It is energy conserving. The packings are available for column sizes from DN – 50 to DN – 450 in standard lengths of 200mm pad modules .

MATERIAL   Pipe : 1. Seamless Carbon Steel ASTM A 106 Gr.B.Sch-402. ASTM A 312 TP 304,Sch-40 Flanges : 1. Made from IS 2062 Plates/ASTM A 1052. ASTM A 351 Gr.CF 8 Liner : PTFE in accordance with ASTM D 1457 Vent Extensions   When the lined piping system will be lagged, please specify that the spools and fittings should be supplied with vent extensions, these 75mm long extension protrude through the lagging allowing the correct venting of the lined equipment. Venting   All lined piping systems must have vent holes drilled through the steel body. This is for 2 reasons, firstly to vent any gasses that may permeate through the liner witch can be detrimental to liner life to the atmosphere rather than allow them to build up behind the liner trapped within the steel pipe. Pipe spools less than 500mm have 2 off vent holes located centrally, longer spools have 4 vent holes 1 pair located at each end.
