Pipe spools of sizes up to DN-300 and a maximum length of 3000mm. These spools are seamless pipe sections to which the plastic liner is thermally locked from inside & flared at ends conforming to ASTM A 106 sch-40 conforming to ASTM F 1545 suitably provided with vent holes to prevent liner failure against different temperature and pressure and permeation conditions. These lined spool pipes can be supplied with lose or fixed flange design to any drilling specification upto DN – 300 sizes. As a solution to customer’s applications Jacketed Lined Pipes can also be made available.
