PTFE Lined Pipe Fittings
Frequently Asked Questions
Can’t find your duty condition here? Send us the media, size, pressure and temperature and we will specify the valve. Contact us
What are PTFE lined pipe fittings?
They are standard steel pipe fittings — elbows, tees, crosses, reducers, flanges and straight pipe spools — lined internally with PTFE so the corrosive stream never touches the metal. Used together with lined valves they let you build an entire acid or solvent line in ordinary carbon steel, at a fraction of the cost of an exotic alloy system, while keeping the same flange standards and layout as a normal piping run.
Which lined fittings does MVS manufacture?
Eleven items: Pipe, 90° Elbow, 45° Elbow, Equal Tee, Reducing Tee, Instrument Tee, Equal Cross, Unequal Cross, Concentric Reducers, Eccentric Reducers and Reducing Flanges.
Pair them with the PTFE Lined Valve range for a complete lined system.
Why choose lined fittings instead of an alloy or plastic piping system?
Solid alloy piping in Hastelloy or titanium resists the same media but costs several times more, and thermoplastic piping cannot take the pressure, temperature or mechanical abuse of a steel line. A lined system gives you a steel pressure envelope with a fluoropolymer wetted surface, standard flange dimensions, and the ability to replace one spool without redesigning the run.
When do I use a concentric reducer and when an eccentric one?
A concentric reducer keeps both pipe centrelines aligned and is the default for vertical runs. An eccentric reducer keeps one side flat, which is what you want in a horizontal line: fitted flat-side-up it prevents gas pockets, and flat-side-down it lets liquid drain rather than pool. On pump suction lines the eccentric reducer fitted flat-side-up is standard practice to stop vapour collecting and causing cavitation.
What is the difference between an equal and an unequal tee or cross?
An equal tee or cross has all branches the same nominal bore as the run. An unequal (or reducing) fitting has a smaller branch, which saves you a separate reducer and one more set of lined flange joints — fewer joints means fewer places a liner can be damaged during assembly. Specify the run size first, then the branch size.
What sizes, flange standards and lining thickness are available?
Fittings are supplied across the same range as the lined valves, DN 15–250, with lining at 3–5 mm. Flange drilling follows ASA #150, DIN 2632/2633, BS 10 Table D, E or F, or customer specification, so lined fittings drop straight into an existing flanged layout. Give us your line size, flange standard and media and we will quote the spool list.
Which lining materials can you apply?
PTFE for general chemical service, PFA where the media is highly permeating or the temperature is higher, FEP as a cost-effective option at lower temperature, and PVDF, PP or HDPE where those suit the duty better. As a guide, PTFE works to about 180 °C, PFA to 260 °C, FEP to about 150 °C, PVDF to about 140 °C and PP to about 90 °C.
How is lining integrity verified before dispatch?
Every lined item is spark tested at high voltage to confirm the lining carries no pinholes or thin spots. A pinhole is invisible but lets acid reach the steel, so the fitting corrodes from the inside with no external sign until it fails. Ask for the spark test certificate with every lined delivery.
What should I watch when installing lined fittings?
Use full-face gaskets and tighten flange bolts evenly in a cross pattern to the specified torque — over-torquing crushes the liner flare and is the commonest field failure. Never lever a fitting into position or strike the lined face. Align and support the pipework so no bending load is carried through the fitting, and do not cut or weld a lined spool to length; order it made to size.
Are you a manufacturer, and what is your minimum order quantity?
MVS manufactures at its own works — since 1978, ISO 9001:2015 certified — and exports across several continents. The minimum order quantity is 20 pieces. Made-to-length spools, special flange drilling and non-standard liner combinations are built to order; send us an isometric or line list and we will quote against it.
