Note:

Rotationally-lined "Complex Shapes" are available lined with Tefzel® ETFE through 24" dia. Housing and flange material can be carbon steel or stainless steel. These include manifolds, branched elbows, reducing laterals, double and triple branch instruments tees, etc, per customer requirements. Tefzel® liner is unpigmented. Check Resistoflex chemical resistance data for max. use temperature of Tefzel® with various media. Liner selection is responsibility of the customer. Contact factory for more information.

2. FITTING REQUIREMENTS - DUCTILE IRON:
Fittings conform dimensionally to ANSI B16.42. Metallurgy is ASTM A395 ductile iron.
3. FITTING REQUIREMENTS - CAST STEEL:
Fittings conform dimensionally to ANSI B16.5. Metallurgy is ASTM A216 Grade WCB cast steel.
4. FITTING REQUIREMENTS - FABRICATED CARBON STEEL:
Fittings conform dimensionally to ANSI B16.5. Metallurgy is as follows: Instrument Tee, Lug Body Instrument Tee Body is SAE 1010-1030 steel. Outlet is ASTM A587, ASTM A53/A106 Grade B, or SAE 1010-1030 steel. Flanges are ASTM A105 forged steel. Reducing filler flange is ASTM A516 GR 70 or SAE 1010-1030 steel.
5. LINER REQUIREMENTS:
Resin for 1" through 4" is a polyvinylidene fluoride/hexafluoropropylene copolymer. Resin for 6" and 8" is a polyvinylidene fluoride homopolymer per ASTM F1545. Standard liners are black in color. The minimum liner thicknesses of flanged fittings are:

Size	Liner Thickness
(NPS)	(Inch)	(Millimeters)
1"	0.170	4.3
1-1/2"	0.180	4.6
2"	0.190	4.8
2-1/2"	0.200	5.1
3"	0.210	5.3
4"	0.210	5.3
6"	0.250	6.4
8"	0.250	6.4

D.

The minimum outside diameter of the plastic sealing surface per ASTM F1545 is:

Size	Minimum Sealing Diameter
(NPS)	(Inch)	(Millimeters)
1"	1-7/8"	48
1-1/2"	2-11/16"	68
2"	3-7/16"	87
2-1/2"	3-15/16"	100
3"	4-5/8"	117
4"	5-15/16"	151
6"	8"	203
8"	10-1/16"	256

E.

The minimum liner flange face thickness is 0.100" (2.54 mm).

6. OPERATING REQUIREMENTS:
Service temperature: For Polyvinylidene Fluoride:    0° F (-18°C) to 275°F (135°C) For Polyvinylidene Fluoride/Hexafluoropropylene Copolymer:    -20°F (-29°C) to 275°F (135°C)

Note:

Operating temperature limitations may be encountered depending upon specific chemical environments.

B.

Pressure: The maximum allowable working pressure equals the corresponding ANSI pressure-temperature rating per the designated metallurgy.

C.

Vacuum: 1" through 8" standard fittings have full vacuum rating to 275°F. Complex Shapes vacuum rating is undetermined. Testing can be provided at an additional charge.

7. STORAGE AND HANDLING REQUIREMENTS:
Avoid dropping or impacting fittings with heavy objects or storing near high traffic areas. Uninstalled lined fittings should not be stored or handled at temperatures below 0°F (-18°C).
8. PAINT:
Paint is a two component epoxy primer, formulated on proprietary polymer technology, which provides rapid cure and overcoating even under low temperature conditions. The maximum external temperature rating is 212°F (100°C) Rotationally-lined complex shapes will receive a two-part polyamide epoxy primer with a max external temperature rating of 250°F.
9. INSPECTION AND QUALITY CONTROL:
Each standard fitting passes a 15,000 volt minimum electrostatic spark test to ensure integrity of the plastic liner. Complex shapes receive either a 12,500 volt minimum electrostatic spark test or a 425 psig hydrostatic test. All parts pass visual inspection. The sealing surface of the liner is free of defects that would impair sealing effectiveness. Wooden or plastic end protectors are used to protect the plastic faces. End protectors should stay in place until immediately prior to installation. Fittings are labeled with a sticker which identifies the plastic liner type and the flange material. A black nylon band to identify the liner as PVDF is affixed to all fittings. Products are identified with molded date tabs on the plastic faces or are impression marked for material traceability.
