M.E.G.A. S.p.A. has always stood out for its multitechnological capabilities and highperformance manufacturing, efficiently and flexibly carrying out the entire production cycle of each pipe, starting from forging through to the final testing phase and any inherent certification. Thanks to continuous investments in new technologies, M.E.G.A. is able to obtain seamless pipes from a forged bar up to 11,000 mm in length and 1,400 mm in outside diameter. The special machining process enables M.E.G.A. to produce special seamless SMLS pipes as thin as 20mm (depending on the other dimensions) as well as large diameters. Pipes can be manufactured from carbon steel, stainless steel, duplex and superduplex stainless steel, and can be plated with CRA material (typically UNS N06625 or 316L) to ensure corrosion resistance. DSS and SDSS pipes can be produced to be Norsok M650 compliant.

Duplex UNS S31803/1.4462 is a duplex stainless steel with approximately 50% ferrite and 50% austenite. This grade has good mechanical strength at room temperature, resistant to corrosive attack, including pitting and is resistant to stress corrosion cracking. The grade is a successful alternative to the normal 300 series austenitic stainless steels, where its higher strength and resistance to stress corrosion cracking is required in critical applications. Please note that we have a minimum order value of £10,000.

The microstructures inside duplex stainless steels are approximately 50 per cent austenite and 50 per cent ferrite, and consequently duplex products share the physical properties of both ferritic and austenitic grades. Duplex stainless steels are resistant to the cracking caused by chloride stress corrosion in austenitic grades, and have improved resistance to localised corrosion. This family of stainless steels has roughly twice the yield strength of their counterpart austenitic grades . Higher hardness values provide better wear resistance for high precision tubes. Duplex stainless steel tubes have high hardness and wear resistance propertiesDuplex steels are easily welded and formed, similar to austenitic grades. Depending on chromium, nickel and molybdenum content, duplex stainless steels are divided into four main categories: lean duplex, duplex, super duplex and hyper duplex. Please note that we have a minimum order value of £10,000.

GENERAL TUBES & PIPES (GTP) These tubes & pipes for general application are used as elements for pipelines in a wide variety of industries BOILER TUBES Boiler tubes are used in the heat generation industry as part of tubular components for boilers in power and industrial plants. INSTRUMENTATION TUBING (IT) High precision stainless steel tubing. HEAT EXCHANGER TUBING (HEX) Heat exchanger tubes are designed to transfer heat and are mostly used in the heating, cooling, ventilation, condensation and evaporation processes. HOLLOW BARS (HB) Thick-walled seamless stainless steel tubes used for mechanical purposes.

NEMS electrical insulation insert is a one-piece pipe product serves to protect the pipeline from electrochemical corrosion in areas affected by stray currents. Installed -at the boundaries of sections of electrochemical protection of pipelines -on the borders of property plots -at the boundaries of pipeline sections with different types and quality of protective coatings or a significant change in the specific electrical resistance of the soil -for electrical separation of aboveground sections of pipelines with a length of more than 1000 m from underground sections -a method for identifying pipeline sections that are affected by stray currents, as well as inductive AC guidance -at integrated gas and oil treatment plants, booster compressor stations or tank farms Advantages -Withstand heavy mechanical loads -The service life corresponds to the service life of the gas pipeline -Installed on all categories of gas pipelines -Operating temperature +150 C and above

Stainless steel tube fittings are a mechanism used both to seal and to grip tubing. The mechanical advantage and geometry of this kind of fitting produces a leaktight assembly. 316L stainless steel tube fittings adopt High grade stainless steel and sealing materials, the fittings can be rapid installed and disassembled. Stainless steel tube fittings consist of four parts: body, front ferrule, back ferrule and nut.
