DESCRIPCIÓN: Tube fittings with Megalok® double compression ring system MECESA is pleased to present the MEGALOK fittings in its desire for perfection and better service, trying to provide as much information as possible and extending its range to the needs that we believe are most frequent. All this is the result of our constant line of avant-garde in the very varied production of fittings.

They are manufactured in three types of materials: 316 grade stainless steel, carbon steel and brass. In installations with plastic tubing, the rings will be made of nylon for brass fittings and PTFE for stainless steel fittings. On request, they can be manufactured in other materials (see Special Materials catalogue).

Stainless steel and brass fittings are supplied pickled and passivated, and carbon steel fittings are phosphated. Other finishes are available on request. The tube shall have a smooth surface finish, free of grooves in order to achieve a perfect assembly of the two rings to the tube.

PIPE, in inches, from 1/8 "OD to 1 "OD. PIPE, in millimetres, from 4 mm to 25 mm. Adapters for PIPE from 1/8" to 1/2" to millimetric TUBE.

Consists of a body with a seat for the pipe, two compression rings and a locking nut. The hermetic connection of the tube to the fitting body is achieved by the pressure exerted by the two rings on the tube when they are pressed by the nut. The function of the front ring is to seal and that of the rear ring is to fix the tube to the fitting. Due to its special conception, both in design and in the variety of materials in which it is made as well as in its connections, it allows it to cover a wide range of applications.

Applications: In vacuum, low and medium pressure, especially suitable for high pressures, or any other that requires hard work; Food field and laboratories; Resistance to the most corrosive acids; Use in hydraulic installations and gases; Suitable for pipes of stainless steel, carbon steel, copper, plastics, etc.; Can be used for high temperature and cryogenic applications; Vibration resistant; Threaded connections, NPT ANSI/ASME B1.20.1, BSPT-ISO 7R, BSP-ISO 228 and optional in DIN 3852 BSP/METRICA.

Fittings and Piping Threaded Fittings Light Series

Application

Food, Power, Gas & Bellows; Cryogenic, Nuclear, Oil & Bellows; Gas, Chemical, Water Treatment

DESCRIPCIÓN: As a complement to the forged accessories according to ASME B16.11, MECESA introduces in its range of fabricators the accessories of the MECEPRIM SERIES, accessories with which we try to increase the possibilities in types of threaded couplings from forged or rolled parts and decrease in some cases of wall thicknesses, and indicating in each accessory the maximum working pressure, determined from the indications of the ASME B31.1 standard.

They are manufactured in three types of materials: 316 grade stainless steel, carbon steel and brass. On request we manufacture in other materials. Such as 304 stainless steel, Hastelloy, Inconel, etc... among others.

Stainless steel fittings are supplied pickled and passivated, carbon steel fittings are phosphated and brass fittings are pickled. The connection dimensions correspond to the thread from 1/8" to 1".

Meceprim fittings have been carefully designed to comply with the characteristics indicated in this catalog according to ASME B31.1 and ASME B31.3 standards, manufactured with a high level of quality.

Threaded connections are made according to NPT according to ANSI/ASME B1.20.1M BSPT according to ISO 7 and BSP according to DIN 3852-B.

All Meceprim fittings in accordance with ASME B31.1 are marked in accordance with MSS-SP25.

Excellent thread machining of the fittings guarantees a high quality connection and visual appearance. We have standard materials, dimensions and connection types, but we have other specials not catalogued, to facilitate the request of any modification of our standard product.

Fittings and Piping Fittings for welding tubing

Application

Food, Power, Gas & Bellows; Cryogenic, Nuclear, Oil & Bellows; Gas, Chemical, Water Treatment

DESCRIPCIÓN: Meceweld welding fittings are used exclusively for connecting to instrumentation piping. They are suitable for the assembly of high pressure circuits with a high degree of responsibility subjected to the harshest and most variable working conditions. The main part of the fittings is their specially machined connection nipple or socket with rigorous tolerances. They have been analytically determined from the general requirements of ASME B31.1, ASME B16.11 and ASME B16.34. They are manufactured in two types of materials: 316 grade stainless steel, carbon steel and brass. On request we can manufacture 304 Stainless Steel, Hastelloy, Inconel, among others (see Special Materials catalog). Stainless steel fittings are supplied pickled and passivated and carbon steel fittings are phosphated. In inches, from 1/4 "O.D. (6.35 m.m.) to 1 "O.D. (25.4 m.m.); in millimeters, from 6 to 20 m.m. Fittings for other pipe dimensions can be supplied upon request. To connect black Pipe (ASME B36.10 M, ASME B36.19M) to calibrated pipe (Tubing), a mixed adapter is provided to allow this variant. Each working pressure is calculated for a temperature range from -10ºF to 100ºF (-29ºC to 38ºC). The operating conditions for other temperatures can be determined from the following equation: Pt = (Pn*K)/1000 = (Bar) Pt = Working pressure at the desired temperature. Pn = Working pressure of the fitting according to its corresponding section and reference. K = Correction coefficient (Catalog Tables). Do not use 316 grade stainless steel fittings where the service temperature may exceed 1000°F (538°C). For 316 grade stainless steel fittings where the service temperature may exceed 1000ºF (538ºC), this should be indicated in the order. Prolonged use of carbon steel at temperatures above 800ºF (427ºC) is not recommended.
