Cast Iron Unions
Kalyan Steel Centre produces cast iron unions that are made from malleable cast iron, also known as black‑heart or grey iron, and are offered with BSP or NPT threading. The product range covers nominal sizes from ½ inch to 4 inch, allowing selection for a broad spectrum of pipe diameters used in industrial systems. Each union complies with ASTM A197 and ISO 49 standards, providing confidence in dimensional accuracy and material performance. The supplier also mentions export‑grade packaging designed for safe overseas transport.
Malleable cast iron typically contains 2‑4 % carbon and 1‑3 % silicon, giving the fittings a good balance of strength and ductility. In practice, unions of this class are rated for pressures up to about 150 psi (typical) and can withstand temperatures up to 250 °C in normal service. Tensile strength for the material is usually in the range of 250 MPa, which aligns with standard cast iron specifications. These characteristics make the unions suitable for water supply, plumbing, oil‑and‑gas and HVAC applications where reliable disconnection is required.
Industrial plants, water treatment facilities, construction projects and large‑scale plumbing contractors are the main buyers of these unions. Kalyan Steel Centre highlights flexible minimum order quantities, enabling both small‑batch and large‑volume purchases. Buyers should confirm the exact lead time, Incoterm and payment terms such as L/C or T/T before finalising the order. The supplier also notes that ISO and SGS certifications are available, but the specific certificates should be requested from the seller.

Sourcing Cast Iron Unions from Kalyan Steel Centre - India Import Guide
Prior to ordering, verify the exact size, thread type and pressure rating required for your piping network. Request the mill test report that confirms the carbon and silicon content of the malleable cast iron, as well as the certification documents for ASTM A197 and ISO 49 compliance. Confirm whether any additional surface treatment, such as a protective coating, is needed for your operating environment.
Shipping from the Kalyan Steel Centre facility typically proceeds from the port of Mumbai. Buyers should agree on the expected lead time, the preferred Incoterm - commonly FOB Mumbai or CIF destination - and the payment method, with L/C and T/T both accepted. Clarify container loading plans and any special handling instructions in the pro‑forma invoice to avoid delays.
Quality control usually includes a dimensional inspection, a visual check for casting defects and a hardness test to validate material properties. Arrange for a third‑party inspection agency to issue a pre‑shipment report, and ask for the mill certificate that details the material composition and test results. These documents are essential for customs clearance and for confirming that the unions meet your project specifications.
