What is ptfe ansi flange?

The two-piece interleaving design of PTFE ANSI FLANGES allows rings to be installed after the stub ends or angle rings have been fused, welded, or glued to simplify installation. Flanges save your money by, expediting repairs to reduce labor costs, and by minimizing down time to maximize productivity. PTFE Flange Gasket rings are used in place of standard one piece rings on all types of piping including carbon steel, ductile iron, stainless steel, polyethylene, fiberglass, and even PVC and CPVC. The backing rings fit behind molded fiberglass flanges and molded PVC and CPVC flanges. These backing rings facilitate higher bolt torques than customarily allowed on molded fiberglass and plastic rings.

PTFE flange hose eliminate the cracking which commonly occurs on those types of molded flanges. If a customer needs split flange or two-piece backing ring for a particular line in your system, you can order it from PTFE ANSI flange manufacturers. ,

In case if the exact item is not there with PTFE ANSI flange suppliers then it is possible to custom manufacture it using standard materials and non-standard alloys. Flanges and backing rings are made to most standard specifications, or configurations, including any national or international standard PTFE ANSI flange dimensions.No matter how complex your system is Type 05419 ANSI Flanges introduce an element of refreshing simplicity. You’ll find installation and replacement with flanges to be quick and effective. Utilize an interleaving two-piece design where the two half rings share common bolt holes and interlock around a pipe with rigidity and strength. This proven design of PTFE/Teflon Hose with Flange Ends has been used in the fluid process industries worldwide since 1955.

Custom rings can be engineered and produced quickly. By eliminating the need cut and re-weld pipe ends when replacing backing rings flanges have proven to reduce replacement time by as much as 66%. Every minute spent on a redundant or lengthy repair operation is a minute where your production is stalled and your profits diminishing.PTFE Flanges are designed to significantly reduce replacement downtime, bringing your line back up in no time and putting money directly back into your budget.

Teflon flange spacers are made of carbon steel, 304L and 316L stainless steel, PVC/CPVC, and special alloys including Titanium, Hastelloy, and several duplex and super duplex materials. Our most common coatings include electro-zinc plating, e-coat epoxy, teflon coated flange and corrosion resistant paint. They are designed to fit steel and stainless tube and pipe stub ends and angle rings, polyethylene pipe stub ends and flange adapters, ductile iron pipe, fiberglass pipe, and PVC/CPVC/PVDF piping.

There are two solutions to strengthen and eliminate cracking molded PFA Flange Adapters. Lightweight rings designed to back-up and strengthen fiberglass reinforced pipe flanges. PTFE lined reducing flanges fit behind molded fiberglass reinforced pipe flanges, effectively dispersing bolt stresses, to facilitate greater allowable bolt torques, and eliminate cracked FRP flanges. Spacer Plates in PTFE flange tape section are engineered to fit between fiberglass flanges and raised face flanges to preclude bending of the fiberglass flanges. Spacer plates are available in a variety of materials including coated carbon steel, polypropylene, and stainless steel.

Types of Fluoropolymers and Chemical Resistance Comparison

Category (Name)	Melting Point and Operating Temperature	Chemical Resistance
PTFE	m.p. 327oC, W.TEMP(MAX) 260oC	Excellent chemical stability;, PTFE don't interact with the vast majority of chemicals and solvents., However, it is vulnerable to molten alkali metal., PTFE also interacts with fluorine gas and fluorine compounds, such as CIF3. OF2, under high temperature and high pressure environments
ETFE	m.p. 270oC, W.TEMP(MAX) 150oC	Similar to the chemical resistance of PTFE, but easily corroded by nitric acids. Has chemical resistance on par with PTFE, but easily corroded by certain chemicals such as nitric acid.
PCTFE	m.p. 327oC, W.TEMP(MAX) 260oC	Highly crystalline, high polymer material, with superior permeability properties.
PFA	m.p. 327oC, W.TEMP(MAX) 260oC	Similar to the chemical resistance of PTFE, with superior mechanical and sanitary properties.
FEP	m.p. 327oC, W.TEMP(MAX) 260oC	Similar to the chemical resistance of PTFE, but has slightly lower operating temperature.
PVDF	m.p. 327oC, W.TEMP(MAX) 170oC	Easily dissolved by fuming sulfuric acid, high temperature sulfuric acid, or caustic soda above 100oC; also bloats or dissolves when interacting with strong solvents such as aceton、ketone、DMA, or extremely alkalic primary amine such as n-butylamine.

PTFE flanges are made from the fluoropolymerpolytetrafluoroethylene and are known for being exceptionally corrosion resistant and inert at elevated temperatures. PTFE flanges are inert to most chemical environments including organics, acids, bases, mixed chemicals and hydrofluoric acid. Moreover PTFE flanges are bio-inert and will not leach into or contaminate sensitive pharmaceuticals or food based products.

Compared to other high performance PTFE flange spacer like PEEK or PVDF, PTFE flanges offer the best all-around corrosion resistance especially at elevated temperatures. However the trade-off for its extraordinary corrosion resistance is the lower tensile strength compared to PVDF or PEEK flanges.
