LTS COMPACT FLANGE (ASME CF)

ASME Series - Design based on ASME

VIII Div. 1 Code Rules and suitable for

Pressure Vessel, Pig Launchers, Heat

Exchangers, Separators, Sand Scrubbers,

Closures and a multitude of Process Piping

applications.

Advantages - LTS Compact Flanges

offer over 70% Weight Savings as well as

significant Space savings over standard

ASME B16.5 flanges. LTS offers sizes thru

200” (5,080mm) which fall outside of ASME

B16.47 and MSS-SP44 Standards, and are

manufactured in a multitude of materials.

Size Range - ½” (12mm) thru 200”

(5,080mm). Larger available on request.

Pressure Classes - ASME 150lbs thru

4,500lbs, API 5,000# thru 20,000#, and 

-423ºF (-269ºC) / 1600ºF (871ºC).  

Materials - SA105, SA350-LF2, A694-

F52-F70, AISI 4130, SA182-F316 (L,H),

SA-182-F321 (L,H), SA182-F347 (L,H),

A182-F51, A182-F55, Safurex, Alloy 625,

Alloy 825, Titanium and Hastaloy.

Gasket - The LTS ASME CF Series

Compact Flange uses an all metal                        8” LTS 2500# Flange Assembly (Sch. 160)

Seal Ring with over 50 years of                             Total Weight: 363LBS (165KGS)

service history. Seal materials are                                                   vs;

selected based on application and service           8” ASME 2500lbs Flange Assembly (Sch. 160)

conditions. The pressure energized bore            Total  Weight: 1359LBS (618KGS)

Seals are elastic by design, and therefore,           LTS ASME CF FLANGE 73% LESS WEIGHT

Reusable.                                                                 (actual scale, weights accurate to +/-2%)

Design & Engineering Support - LTS

provides both ASME analytical calculation

methods in accordance with Section VIII

Division 1, 2 and 3 methods, as well as

ANSYS FEA analysis supporting dynamic load,

combination loads and thermal load

applications. LTS specializes in High Pressure

and High Temperature solutions and offers

integrated design analysis for skid and piping

systems using in-house CAESAR II software.

Design Verification - Building on our 

extensive HP/HT experience, LTS offers Project

specific Prototype Testing, as well as Third

Party design review through DNV, Lloyds, ABS

and Bureau Veritas, as required.
