Ayhan Tube Fittings is a trusted manufacturer and supplier of precision-engineered collars in Istanbul, Turkey. Our collars are crucial components used in instrumentation, piping systems, and tube fittings to ensure secure, leak-proof connections. We offer both standard and customized dimensions, with collars available in stainless steel, brass, and carbon steel. Built to meet international standards, including ASTM and DIN, our collars provide tight tolerances, high mechanical strength, and corrosion resistance. Ayhan Tube Fittings serves clients in the chemical, oil and gas, pharmaceutical, and industrial manufacturing sectors.
Collars are generally made from stainless steel (SS316/SS304), brass, or carbon steel, based on system requirements. These materials offer great corrosion resistance, good machinability, and high mechanical strength. Collars have tensile strength between 450–620 MPa, yield strength of 210–310 MPa, and elongation of 20–30%. They are designed to resist stress and deformation during high-pressure operations, ensuring reliable sealing and structural integrity in tube and pipe assemblies.
