90° Seamless Elbows

90 degree seamless elbows are used in a wide range of piping systems – from simple heating and ventilation systems to industrial installations and specialized applications. Typical areas of use include:

• construction and sanitary installations (central heating, domestic hot water),
• food and pharmaceutical industry (where smoothness and lack of contaminants are vital),
• chemical and petrochemical industry (pipelines transporting corrosive media),
• boiler rooms, furnaces, and high-temperature installations (using heat-resistant grades),
• offshore and shipyards (marine installations),
• automotive and workshops (exhaust and intake systems),
• small garage projects and DIY installations – wherever durable piping components are required.

In our offer, you will find seamless elbows made exclusively of corrosion- and high-temperature-resistant steels. We use commonly applied grades, described using both colloquial and technical designations:

• Stainless steel (INOX)– examples: AISI 304 (EN 1.4301). Universal for general applications, resistant to corrosion in many conditions.
• Acid-resistant steel– examples: AISI 316L (EN 1.4404). Highly resistant to chlorides and aggressive chemical environments – often chosen for the food, chemical, and marine industries.
• Heat-resistant steel– grades designed for high-temperature operation (e.g., AISI 310/310S). Used where resistance to oxidation and long-term exposure to high temperatures is required.

In the product specifications in our shop, we provide designations in both the American (AISI/ASTM) and European (EN) systems, making it easier to choose the right grade for your needs.

When selecting 90 degree seamless elbows, it is worth paying attention to several key parameters:

• Steel grade– match the material to the medium (water, steam, chemicals) and working conditions (temperature, corrosive environment).
• Nominal diameter (DN)– elbows must match the other elements of the installation; our offer includes diameters from DN15 (≈21.30 mm) to DN300 (≈323.90 mm).
• Bending radius– short radius (SR, R≈1D) or long radius (LR, R≈1.5D); the choice affects pressure drops and the installation layout.
• Wall thickness / pressure class– important for high-pressure installations; check the PN or corresponding technological designations.
• Connection type– seamless elbows are usually installed by butt-welding, but versions with other ends may be available depending on the offer.

The main advantages of 90 degree seamless elbows are:

• no internal welds – lower risk of corrosion at the seams and a smooth internal surface,
• better performance under pressure and temperature changes – seamless components often exhibit higher structural integrity,
• easier installation and aesthetic finish of the system,
• durability and resistance to mechanical damage depending on the selected steel grade.

Our offer is addressed to:

• installation and contracting companies,
• industrial plants (food, chemical, petrochemical),
• shipyards and the offshore industry,
• manufacturers of heating and boiler equipment,
• workshops and DIY enthusiasts in need of durable piping solutions.

If you are not sure which steel grade or bending radius will be best for your installation, use the filters in the category or contact our technical department. Provide parameters such as: type of medium, maximum temperature and pressure, pipe diameters, and preferred bending radius – we will help you select the optimal component in terms of safety and durability.

90 degree seamless elbows from our shop are a combination of durability, material resistance, and the ability to adapt to various industries – from simple domestic systems to demanding industrial applications. We invite you to browse the offer and contact us regarding technical specifications.
