Frequently Asked Questions

1

What is the difference between galvanized and black malleable iron pipe fittings?

Black fittings are typically used for gas and steam lines where corrosion is less of a concern, while galvanized and black malleable iron pipe fittings provide a zinc coating for water lines and outdoor environments to prevent rust.

2

Do your fittings meet ANSI B16.3 standards?

Yes, all our malleable iron products are engineered and tested to be fully compliant with ANSI B16.3 and BS 5180 standards.

3

Can you produce customized sizes for specialized industrial plants?

Absolutely. We provide custom mold casting services to deliver fittings based on your specific CAD drawings and pressure requirements.

4

What is the maximum pressure rating for your malleable iron fittings?

Standard fittings are rated for 150 PSI, but specialized high-pressure versions can be produced to meet 300 PSI requirements upon request.

5

How is the galvanizing process handled to ensure uniformity?

We utilize a continuous hot-dip galvanizing bath with automated agitation to ensure a consistent zinc layer thickness across all complex geometries.

6

What is your typical lead time for bulk export orders?

Depending on order volume, bulk lead times range from 15 to 30 days, ensuring rapid deployment for your project timelines.
