plastic lined pipe is made with a locked-in liner to minimize
the adverse affects of differential thermal expansion between
the liner and the steel. Both processes used are exclusive
Pipe - annealing process relieves stress in the liner
while expanding the liner within the steel housing.

manufactures thousands of different shaped plastic lined fittings
according to ANSI dimensions. PP, PVDF, and PFA fittings are
all injection or transfer molded. Fittings lined with Tefzel®
ETFE and special shapes are roto-lined in custom housings.
PTFE liners are made by isostatic molding. Fittings are generally
differentiated by their metallurgies.
Iron - Economical Glass 150 fittings with fixed
flanges for PP and PVDF liners and certain PTFE fittings.
Cast Steel - High strength Class
150 or Class 300 ratings for PP, PVDF and PFA liners. Flanges
Fabricated Steel - High performance
Class 150 or Class 300 fittings with rotatable flanges used
with PTFE liners. Can be made to DIN or JIS flange dimension.
Can also be fabricated using stainless steel or exotic alloys.
- Patented flangeless fittings designed for use with CONQUEST®
manufactures four different types of valves for corrosive
services. The diaphragm and clamp valves provide throttling
capabilities, and vertical and horizontal checks prevent backflow
in process lines.

Lined with Tefzel®, these custom products are
available through 24" dia., with ANSI or custom dimensions.
Contract lining and manufacturing services are available for
pump, valve, and flowmeter OEM's.
PTFE-Lined Bull's Eye sight flow indicators are used to observe
the fluid and flow characteristics of process fluids. Sight
flows can be optionally equipped with drip lips and/or flutter
flow indicators. These products are available in 1" -
6" from Resistoflex USA and in 8" - 16" diameter
as manufactured by Resistoflex GmbH.
expansion joints are made of contour molded PTFE, providing
exceptional corrosion resistance and flex-life. The flexible
liner is molded over the metallic sealing face. Different
numbers of convolutions accommodate varying degrees of misalignment,
axial travel, and angular deflection between components:
Convolutions - Flexible Coupling
