ANSI / ASTM Pipe And Fittings Standards

Carbon Steel Pipe

CS pipes material are seamless or welded conforming to ASTM A 106 Gr.B / ASTM A53 in standard wall thickness.

Stainless Steel Pipe

SS pipes material are 55304, seamless ASTM A213, schedule 40 wall thickness.

Flanges

Flange material is as per ASTM A 105 and for DIN/BS 10 standard. Flange is made from plate material 152062 Gr. -A. Stainless steel flange is as per ASTM A 182.

Fittings

Fittings are fabricated from pipe or alternatively ductile iron casting conforming to ASTM A395, casting grade. Flange material ASTM A 105 (optional)

Design Standard

Flanges for lined products shall have ANSI class 150 bolt circle diameters, bolt hole diameter and numbers of bolt holes in accordance with ANSI 816.5, unless otherwise specified flanges are ductile iron as per ANSI B 16.42. Fittings shall have ANSI class 150 face to centerline dimensions in accordance with ANSI B 16.42 unless otherwise specified. No welding shall be done on pipe components in the field. All lined pipes and fittings shall generally conform to ASTM F1545.

Application

Temperature PTFE:
Maximum continuous service temperature 200° C. Melting temperature 327° C.
PFA: Maximum service temperature 200° C. Melting temperature 305° C.
FEP: Maximum service temperature 160° C. Melting temperature 260° C.
Pressure Rating As per ANSI B 16.5, 150 lbs.

Chemical Resistance

The well known PTFE / PFA / FEP is chemically inert to most of the chemicals and solvents with the exception of molten alkali metals. PTFE can be used with aggressive media such as hydrofluoric acid, fluoric acid, fuming sulphuric and nitric acid hot sodium hydroxide solutions and chlorine gas, hydrogen and nitric oxides.

Operating Pressure

PTFE lined pipe work can be used upto 20 bar I 300 psi.g. Full vacuum resistance depending upon the process conditions. Details to be provided by client for specific applications. Resistance to Light & Atmospheric Conditions PTFE may be used without any problem in the open air and there are no mechanical and electrical characteristics even then subject to extreme climatic conditions.

Electrical Properties

PTFE has goods electrical insulations with a very low dielectric constant. * Specifications are subject to change without notice. Dimensions are indicative and informative only.

Inspection

Dimensional check: As per standard:
Hydro Test
All 150 class pipes and fitting shall be tested at 25 bar after lining and 46.5 bar for 300 class pipes and fittings.
Electrostatic Test A test voltage of 15 kv to 25 kv depending upon liner thickness.
