![]() ![]() Specifications: Anvil Variable Spring Hangers are welded in strict accordance with ASME Section IX. Permanently attached travel stops available upon request.Īpprovals: WW-H-171E (Types 51, 56 and 57), ANSI/MSS SP-69 and MSS SP-58 (Types 51, 52 and 53). The travel stop is painted red and is installed at the factory with a caution tag attached calling attention that the device must be removed before the pipe line is put in service. The complete travel stop, the up travel stop only for cold set purposes or the down travel stop only which may be employed during erection, hydrostatic test (Anvil permits a hydrostatic test load of 2 times the normal operating load for the spring hanger) or chemical cleanout will be furnished only when specified. Travel stop: The functional design of the pre-compressed variable spring hanger permits the incorporation of a two-piece travel stop that locks the hanger spring against upward or downward movement for temporary conditions of underload or overload. Recommended for ambient temperatures up to 200° F.Does not affect the flex life of the spring.Protects from a wide range of corrosives.For protection against severe weather conditions or moderate corrosive conditions, the parts of the hanger are galvanized per ASTM A-153, except the spring, which has a protective coating and the load column for Type F, which is electro-galvanized. Standard Finish: Painted with semi-gloss primer.Ĭorrosion Resistant: Anvil offers corrosion-resistant and weather resistant Variable Spring Hangers to fill vital needs in the chemical and refinery industries as well as in modern outdoor power plant construction. Casing protects the spring from damage and weather conditions.Piston cap serves as a centering device or guide maintaining spring alignment. ![]() Spring and casing are fabricated of steel and are rugged and compact.Load indicator is clearly seen in the slot, simplifying reading of the scale plate.Calibration: all Anvil Variable Spring Hangers and supports are calibrated for accurate loading conditions.Saves valuable erection time because spring is precompressed close to 1/2" of the working range.Prevents the spring supporting force from exceeding the normal safe limits of variations.Reduces the installed height of the overall hanger assembly.Saves up to 50% in headroom by reducing the length of the hanger. ![]() In addition to these three facilities Anvil also has Hanger fabrication facilities in Houston, Texas to service the Gulf Coast Engineered Hanger requirements.Precompressing the spring into the hanger casing provides the following advantages: Columbia is ISO 9001 certified and is a quality manufacturer of malleable,ĭuctile and cast iron products.
