Standard Oil & Gas pipe fittings

Standard fittings are designed for pressure lines, process piping, and hydraulic systems operating in oil and gas facilities.

They are available in threaded, socket weld (SW), and butt weld (BW) configurations.

Elbows, Tees, and Crosses

• Equal tees
• Reducing tees
• Crosses
• Lateral tees
• Flow tees
• Target tees
• Barred tees

These fittings are engineered to withstand high pressure, erosive flow, and piggable pipeline conditions.

Branch outlet fittings (self-reinforced connections)

M.E.G.A. manufactures high-performance branch outlet fittings designed according to ASME B31 and related codes.

These fittings reduce stress concentration and improve fatigue resistance in high-pressure systems.

Megalets

Self-reinforced 90° branch connections for oil and gas pipelines.

Advantages:

• Reduced filler material
• Fewer welding hours
• Improved NDE controllability
• Lower Stress Intensification Factor (SIF)

Latromegalet

Allows branch connections at angles besides 90°.

Elbomegalet

Designed for installation on elbows or bends.

Insert Megalet

Welded directly inside the run pipe for maximum fatigue resistance and full radiographic inspection capability.

All branch outlet fittings are available with:

• Butt weld ends
• Socket weld ends
• Threaded ends
• Flanged configurations

Special Oil & Gas pipe fittings

M.E.G.A. designs and manufactures special engineered fittings developed from scratch according to customer specifications or international codes.

Design standards include:

• ASME BPVC Section I, III, VIII Div. 1 & 2
• PED, RCC-M, EN 13480, EN 10253

Special Tees

• Double barred tees
• Triple tees
• Double crosses
• Special lateral fittings

Designed for severe operating conditions, including high pressure and vibration-induced fatigue.

Special Wyes and Piggable Wyes

Engineered Y-shaped fittings for piggable pipelines and subsea installations.

Available in symmetrical and asymmetrical configurations, with optional CRA overlay.

Special Flanges

Manufactured according to:

• ASME B16.5
• ASME B16.47
• API 6A
• ASME BPVC Section VIII

Types include:

• Welding neck flanges
• Long welding neck flanges
• Misalignment flanges
• Anchor flanges
• Blind flanges

Nozzles for Oil & Gas

Reinforced nozzles designed for:

• Pressure vessels

• Reactors

Available in flanged, non-flanged, inclined, and transitional configurations.

Engineered to resist fatigue, high pressure, and corrosive environments.

Seamless forged pipes for Oil & Gas

M.E.G.A. manufactures seamless forged and bored pipes for use in:

• Upstream production systems
• Midstream transportation lines
• Downstream refining plants

Carbon Steel Seamless Pipes

For standard and high-pressure service.

Stainless Steel Seamless Pipes (ASTM A312 Series)

For corrosive and high-temperature environments.

Duplex and Super Duplex Pipes

For aggressive offshore and subsea environments.

Optional CRA internal cladding (e.g., UNS N06625, 316L) available for enhanced corrosion resistance.

Welded pipe fittings and prefabricated spools

Thanks to its in-house welding division, M.E.G.A. manufactures:

• Welded pipe fittings
• Prefabricated spools
• Special assemblies

All welds are certified and controlled under the company’s quality management system.

Engineered Spools

Custom-designed assemblies, including:

• Pipes
• Flanges
• Fittings
• Weld overlays

Fully produced in-house, from raw material sourcing to final testing and certification.

High-quality materials

M.E.G.A. fittings are engineered and produced in a wide range of materials to ensure maximum reliability in extreme operating conditions typical of the Oil & Gas industry. We manufacture components in:

• Carbon Steel
• Low Temperature Carbon Steel
• High Yield Steel
• Cr-Mo Alloy Steel
• Stainless Steel
• Duplex and Super Duplex Steel
• SMO F44
• Nickel Alloys
• Titanium

This material diversity allows M.E.G.A. to deliver fittings capable of withstanding high pressure, temperature variations, and corrosive environments, both for onshore and offshore applications. Each material is selected and processed according to the specific requirements of international standards — including ASME, API, and EN codes — and validated by finite element analysis (FEA) and non-destructive testing. The in-house forging, heat treatment, and weld overlay capabilities further enhance the mechanical integrity and corrosion resistance of every fitting, ensuring consistent performance over time

Our certifications comply with oil and gas standards

As a supplier to the oil and gas industry, we have achieved high-quality standards, certified by accredited bodies in the oil and gas industry. For organizations active in the oil and gas industry, certification to the relevant standard provides an important opportunity for standardization and improvement.

Certification provides a system for continuous improvement of processes and products. Quality is sustainably assured and can be externally documented. Waste is reduced and the consequences of functional errors that may be caused by products and services are limited. In the chart below you will find all our certifications.
