Metinox Overseas carries a selection of high-quality stainless steel pipe & tube, carbon steel pipe & tube, alloy steel, duplex, and nickel-alloy pipes and tubes for use in projects throughout Bahrain—Manama, Riffa, Muharraq, Hamad Town, Isa Town, and beyond. Each pipe is sent with mill test certificates, and all are specially designed to meet international standards from a single fitting to full-container orders.
In situations where a piping system is required to operate at high pressure, high temperature, and corrosive environments, the strength of the steel behind the system can't be left to chance.
Metinox Overseas is a specialist manufacturer, stockist, and exporter for industrial pipes and tubes for the oil & gas, petrochemical, desalination, power, and construction industries in Bahrain. Each length that is shipped is manufactured under strict quality control, traceable to each heat, and meets recognized ASTM, ASME, API, DIN, and JIS standards.
With a robust ready-stock selection and many years of metallurgical experience, we can convert your inquiry into material delivered to you in no time at all, whether you're looking for a few seamless tubes for a heat exchanger or multiple containers of carbon steel line pipe for a new facility. We are the preferred choice among buyers from the GCC due to our real technical expertise, our transparency on pricing, and our reliability in our port services in Bahrain, Kuwait, and Indian ports. The outcome: the right grade, fully certified, at the right price, on time — with no waiting time for your project's piping.

Pipes vs Tubes: Understanding the Difference
Buyers often use the terms interchangeably, but pipes and tubes are specified differently. The table below clarifies how to order the right product.
| Aspect | Pipes | Tubes |
|---|---|---|
| Sized by | Nominal bore (inside diameter) | Outside diameter (OD) |
| Primary purpose | Transport of fluids & gases | Structural & precision use |
| Tolerance | Standard pressure tolerances | Tighter dimensional tolerance |
| Schedule / gauge | Specified by schedule (SCH) | Specified by wall thickness/gauge |
| Typical shape | Round | Round, square, rectangular |
Seamless vs Welded Pipes: Which to Choose
| Factor | Seamless | Welded (ERW/EFW) |
|---|---|---|
| Manufacture | Extruded from solid billet — no weld seam | Formed from plate/coil and welded |
| Pressure rating | Higher; ideal for critical service | Suited to low/medium pressure |
| Cost | Higher | More economical |
| Best for | Oil & gas, high-temp, sour service | Structural, water, general piping |
Quality Assurance & Testing
Every batch of pipes and tubes passes a documented inspection regime before it leaves us, so the material you receive matches exactly what is on the certificate.
- Chemical composition analysis (spectro / heat-number verification)
- Mechanical testing — tensile, hardness, impact and flattening
- Hydrostatic & eddy-current / ultrasonic testing
- Intergranular corrosion (IGC) and PMI testing on request
- Dimensional and visual inspection to standard
Certifications & Standards
Material is supplied with EN 10204 3.1 mill test certificates and, where required, third-party inspection (TPI) by agencies such as Lloyd's, BV, SGS, DNV and TÜV. Our quality system follows ISO 9001 principles end to end.
