2) Flanges comply with IS2062 Gr. A/ASTM A-105; ANSI B16.5 ASA150 SORF TYPE. Flanges of other specifications available on request.
3) Fittings comply with ASTM A-234 Gr. WPB/ASTMA-395; ASME B16.42; ASTM-106 Gr. B; ANSI B 16.9; B 16.5.
4) For stainless steel, diverse grades may apply.

 

LINING

PTFE: - The lining is made from virgin PTFE (Polytetrafluoroethylene) using PASTE EXTRUSION technology and complies with ASTM F- 1545.
PFA/FEP:- The lining is from pure PFA (Perfluoroalkoxy) / FEP (Perfluoro Ethylene Propylene) using Injection Molding / Transfer Molding process and complies with ASTM F-1545.
FDA Conformity: Upon specific customer requests, the lining of our piping parts complies to the regulations of the FDA.
Antistatic Lining/Conductive Lining can be provided on request.

LINER THICKNESS:


In accordance with ASTM-F -1545 the lining thickness must be 3mm minimum. In practice however, thicker liner mean better safety under vacuum, better resistance against abrasion as well as lower gas permeability.
Other lining thicknesses can be manufactured as per customer requirements

TOLERANCES:


Tolerances of pipes and fittings are defined in ASTM F 1545 as well as ASME B 16.5. The liner thickness may vary by approx. 10%. This applies especially to the area of flaring where the liner thickness may be thinner by up to 20%. This is primarily due to the stretching of the fluoropolymer.

OPERATING PRESSURE:


Up to 20 bar/300 psig or higher upon request.
OPERATING TEMPERATURE:
PTFE: -20Deg. C to 260Deg. C as per ASTM D 1457.
PFA: -20Deg. C to 260Deg. C as per ASTM D 3307.
FEP: -20Deg. C to 205Deg. C as per ASTM D 2116.
These temperatures apply only under optimum conditions. Special conditions may require a reduction in vacuum and pressure
