Frequently Asked Questions

Q: What are the main applications for malleable iron pipe fittings?

They are primarily used for connecting pipelines that transport steam, compressed air, gas, oil, and water in industrial and commercial settings.

Q: What is the difference between galvanized and black heart finish?

Galvanized fittings have a zinc coating for superior rust and corrosion protection, while black heart fittings are uncoated and typically used in applications where corrosion is less of a concern.

Q: Can these fittings handle high-pressure systems?

Yes, they are designed with a working pressure of 1.6MPa and are tested up to 2.5MPa to ensure safety and reliability under pressure.

Q: Which international standards do these pipe fittings follow?

Our products strictly adhere to ISO 49, DIN 2950, and EN10242 standards, ensuring global compatibility and quality.

Q: Do you provide custom designs or specific drawings?

Yes, we welcome buyer's drawings or designs to provide customized fitting solutions tailored to your specific project needs.

Q: What is the typical delivery lead time?

The normal delivery time ranges from 30 to 45 days after we receive the deposit, depending on the quantity and specifications of the order.
