Frequently Asked Questions

Q: What is the primary difference between malleable iron and gray cast iron fittings?

Malleable iron undergoes a heat treatment process that removes carbon, making it significantly tougher and more resistant to impact and shock compared to the brittleness of gray cast iron.

Q: How does hot-dip galvanizing protect these pipe fittings?

Hot-dip galvanizing creates a thick, metallurgical bond of zinc over the iron, providing a physical barrier and cathodic protection against rust and chemical corrosion.

Q: Can these caps be used for high-pressure industrial pipelines?

Yes, our malleable iron caps are designed for pressure resistance. For extreme pressure levels, we recommend using our optional sealing gaskets for enhanced security.

Q: Are these fittings compatible with standard plumbing threads?

Absolutely. We use standard international thread specifications to ensure full compatibility with most industrial and commercial piping systems globally.

Q: Why choose a hemispherical design over a flat cap?

The hemispherical design is superior for pressure distribution, reducing stress concentration and increasing the overall strength of the seal under load.

Q: In which industries are these malleable iron fittings most commonly used?

They are widely used in HVAC engineering, fire fighting systems, municipal water supply, and various heavy industrial manufacturing plants.
