SIGMA POLYMERS ENGINEERING COMPANY

• ABOUT US

  Sigma Polymers Engineering co. is an ISO 9001:2008 approved company established in the year 2008 with factory equipped with well designed amenities to manufacture plastic lined systems. Since beginning, we use “Dupont” make raw material for processing of fluoropolymer lined pipes, fittings, valves and other accessories integral to chemical process industry.

  All Sigma manufactured Lined Pipes, Fittings and Valves are backwards traceable from the finished component to the manufacturing tests, processes and lining materials. Each spool has one flange stamped with the reference of the liner batch used in its construction. This provides traceability back to the liner manufactured, the tests undertaken and the materials certification of the polymer. FEP / PFA moulded items likewise are stamped with a mould reference which again provide traceability back to the manufacturing and test activities and the material certification of the polymers used.
