Lining

PTFE Lining

Advanced fluoropolymer PTFE lining solutions applied to pipes, fittings, vessels, and chemical columns to provide an impermeable, non-stick chemical barrier against aggressive acids and high temperatures.

Complete chemical inertness against concentrated nitric, sulfuric, hydrochloric, and hydrofluoric acids up to 260°C
Thick-wall paste extruded PTFE liner prevents permeation and thermal vacuum collapse in continuous vacuum lines
Seamless flared-over sealing faces eliminate separate gaskets at pipe spool and vessel flange connections
Ultra-smooth non-stick surface coefficient prevents scaling, chemical fouling, and pressure drop in transfer lines

Description

PTFE Lining

Heavy-duty fluoropolymer PTFE lining services engineered by PT Misuba Guna Indonesia for complete internal corrosion protection of carbon steel and alloy piping systems, columns, tanks, and chemical reactors. Using paste-extruded virgin PTFE, PFA, or FEP liners (thick-wall paste extruded or sheet lined), our linings form a seamless, non-stick barrier that resists extreme chemical attack from concentrated acids, strong alkalis, and reactive solvents.

Equipped with thermal paste-flaring technology and vacuum-resistant locking grooves, our lined pipe spools and fittings withstand severe thermal cycling without liner collapse, liner creep, or vacuum deformation.

Custom Engineering Consultation & Ordering Guide

When requesting a quote for PTFE lined pipe spools, vessels, or fittings, please specify line nominal size (DN15 to DN600), total spool lengths (OAL), flange drilling (ANSI 150#/300#, JIS 10K, DIN PN16), operating temperature, vacuum conditions, and specific chemical concentration. Our technical team conducts spark testing (15kV to 25kV) and hydrostatic verification on 100% of lined components prior to site delivery.
