NUFLO Single & Dual Chamber Meter Runs and orifice fittings

The NUFLO model 4042 single-chamber meter run and 4055 dual-chamber meter run are fabricated by trained manufacturing personnel with complete facilities for machining, welding, gauging and inspection. This produces a product with quality and metering accuracy not possible with field-fabricated units. All meter runs are factory-aligned and welded with special equipment that guarantees a straight, smooth meter run without defects. Standard lengths meet AGA/API requirements.

Orifice fitting to meter run alignment can be specified with dowel pins or male/female flanges. These options assure proper bore alignment. Meter runs may be also be manufactured to meet customer specifications.


NUFLO Single- and Dual-Chamber Orifice Fittings

The NUFLO 4042 single-chamber orifice fitting is designed for use in installations in which the line can be depressurized to change or inspect the orifice plate. Economical and lightweight, the single chamber features a simple design with very few parts. This quick and easy method for removing orifice plates reduces shutdown time.

The interchangeability of the orifice plates and retainers between the NUFLO dual-chamber and single-chamber orifice fittings also provides an economy in inventory requirements. Single-chamber orifice fittings are available in flangeweld, weldneck, and flanged types. All NUFLO single-chamber orifice fittings meet AGA/API specifications. Two sets of 1/2’’ NPT flange taps are provided on all single-chamber orifice fittings. They are available in 2’’, 3’’, and 4’’ sizes for sweet, sour, nace, and low-temperature applications.

The NUFLO 4055 dual-chamber orifice fittings are compact, streamlined, and rugged, featuring a simple and rapid method for changing or inspecting orifice plates under pressure. The orifice fittings feature a ball type construction for opening and closing without a complicated gear mechanism. The unique construction incorporates a ball closure with spring-loaded, self-lubricating, moly-filled Teflon® floating seals, thus eliminating the need for periodic lubrication. All NUFLO orifice fittings are manufactured in accordance with ANSI, AGA/API, and ASTM standards and are available in 2″, 3″, 4″, and 6″ sizes.
