• Metline is professional flange manufacturer, with significant exports to Egypt customers. A flange is a flat, circular disk, and by using which, pipes can be assembled or disassembled very easily. We can offer steel flanges in various type such as weld neck flange, slip on flange, blind flange, threaded flange, socket weld flange, lap joint flange, and orifice flange. They are manufactured strictly according to ASME, ASTM and DIN standards, resulting in reliable quality and good performance.

• We manufacture steel flanges in stainless steel, carbon steel, alloy steel, nickel alloys, and aluminium. Metline also has many different steel flanges in stock and ready to ship. Steel flanges in stock include ANSI B16.5 steel flanges, ASME B16.47 Series “A” steel flanges, and ASME B16.47 Series “B” steel flanges. Metline also manufactures custom weld neck and slip on pipe flanges per customer requirements.
• We are devoted to provide the best steel piping solutions for our customers in Cairo, Alexandria, Giza, Shubra El-Kheima, Port Said, Suez, El-Mahalla El-Kubra, Luxor, the biggest industrial and commercial cities of Egypt. We have manufacturing set up, sales and export offices in both India and China to meet the immediate and long term steel flange requirements across the People’s Democratic Republic of Egypt.

• We are a reputed supplier to Egypt with extensive production capacity for supply of steel flanges, socket weld fittings, threaded fittings, elbow, tee, stub end, reducer, cap, swaged nipple. Our production size range for steel flanges is from 1/2” – 60”. We have adopted advanced production equipment and technologies to manufacture steel pipe fittings, elbows, tees, pipe reducers, pipe caps, pipe bend, and flanges. Our products have high strength, good toughness and resistance to corrosion.

• ASME B16.5 and ASME B16.47 cover pipe flanges up to NPS 60 (B16.5 from 1/2″ to 24″ and B16.47 from 26″ to 60″). ANSI B16.47 covers two series of flanges, Series A is equal to MSS SP-44-44, and Series B is equal to API 605 (API 605 has been cancelled).

Types of Flanges Manufactured by Metline Industries

A flange is one of the most widely used pipe fitting. It is used for connecting pipes, valves, pumps and other equipment to form a piping system. The key advantage of using a flange in a piping system is that it allows easy access for cleaning, inspection or modification. Flanges are usually welded or screwed. Flanged joints are made by bolting together two flanges with a gasket between them to provide a seal. We produce welding neck, slip on, socket weld, lap joint, threaded and blind flanges. In addtion to regular known flange types, we also manufacture special flanges such as Orifice flanges, Spectacle blinds, Long welding neck flanges, Weldoflange/Nipoflange, Expander flange, Reducing flange, Groove flanges/Tongue flanges.
