Product Description

Products Details

Flexible couplings, designed to connect rotating shafts and accommodate misalignments, come in various materials to meet specific industry standards. ASTM A536 is a specification developed by ASTM International for ductile iron, also known as nodular or spheroidal graphite iron. When flexible couplings adhere to the ASTM A536 standard, it signifies the use of high-quality ductile iron, ensuring robustness, durability, and compliance with established material specifications.


Material Characteristics:

Ductility: ASTM A536 ductile iron exhibits high ductility, allowing for flexibility and deformation without compromising its structural integrity.
Strength: The material provides strength comparable to traditional gray iron, making it suitable for applications where durability is essential.
Corrosion Resistance:

Coating Options: Flexible couplings manufactured with ASTM A536 ductile iron often incorporate coatings or treatments to enhance corrosion resistance. This is particularly important for couplings used in environments prone to rust or chemical exposure.


Adaptability: ASTM A536 ductile iron is versatile and well-suited for use in various industries, including water and wastewater treatment, manufacturing, and power generation.
Machinability: The material is machinable, allowing for the creation of intricate coupling designs that meet specific application requirements.

Compliance with Standards:

ASTM A536 Compliance: The use of ductile iron meeting ASTM A536 standards ensures that the flexible coupling’s material properties align with established industry benchmarks. This compliance provides confidence in the coupling’s performance and longevity.

Shock Absorption:

Damping Properties: Ductile iron has inherent damping properties, making it effective in absorbing shocks and vibrations. This is particularly advantageous in applications where minimizing stress on connected equipment is crucial.
