Steel Sheets

Seamless elbows are pipe fitting components used to change the direction of a line (e.g., 45°, 90°). They are manufactured without a weld, which provides better resistance to pressure and corrosion compared to welded elements.

Forged flanges are piping connectors made through forging or machining, used to create detachable connections between pipes, valves, and equipment. Forged flanges are characterized by higher mechanical strength than flanges formed from sheet metal.

Concentric seamless reducers allow for a reduction in pipe diameter while maintaining the same center line of the pipeline – they are used where a smooth change of cross-sections is required without shifting the pipe axis.

Stainless steel fitting components are used in a wide spectrum of industries, including:

• food and pharmaceutical industry – sanitarily clean (hygienic) installations,
• chemical and petrochemical industry – process installations resistant to aggressive media,
• marine and offshore industry – installations exposed to saltwater,
• automotive and motorcycle sector – exhaust systems and temperature-resistant components,
• heating, boiler installations, and power engineering – where temperature resistance and material fatigue matter,
• construction and sanitary installations – water, sewage, and ventilation systems,
• small workshops and garages – repairs and modifications of installations, craftsmanship.

Our offer includes components made of various types of stainless, acid-resistant, and heat-resistant steel. Below are the most common grades, their colloquial terms, and popular equivalents:

• Stainless steel 304– (EN 1.4301, AISI 304, X5CrNi18-10). A universal corrosion-resistant steel under standard conditions, easy to process – often used in food and construction installations.
• Acid-resistant steel 316L– (EN 1.4404, AISI 316L, X2CrNiMo17-12-2). Better corrosion resistance in the presence of chloride ions and chemicals – common in the chemical, marine, and pharmaceutical industries.
• Heat-resistant steels (e.g., 310S)– (EN 1.4845, AISI 310S). Heat-resistant steels used where components are exposed to elevated temperatures and oxidation.
• Ferritic steels and others– e.g., grades like 430 (EN 1.4016, AISI 430) used where different mechanical properties and corrosion resistance are required.

The choice of steel grade depends on the working environment: presence of chlorides, temperature, pressure, hygienic requirements, and compatibility with the installation materials.

• Working environment: if the installation comes into contact with seawater or aggressive chemicals, consider 316L or other grades resistant to corrosion in such conditions.
• Temperature and pressure: for high-temperature applications, heat-resistant steels are chosen; for pressure installations, the type of connection (seamless, forged) and the mechanical parameters of the element are crucial.
• Joining method: seamless elements reduce the risk of weak weld points; forged flanges provide higher strength for detachable connections.
• Standards and compliance: for industrial projects, pay attention to the compliance of elements with standards and customer requirements (e.g., European standards/DIN/EN and customer specifications).
• Surface finish: for the food and pharmaceutical industries, a smooth internal and external finish (e.g., polished surfaces) is important, facilitating cleaning and preventing the accumulation of contaminants.
