A Cast Flange is a strong and cost-effective component designed for joining pipes, valves, and equipment across various industrial applications. Manufactured from cast iron or cast steel, these flanges are known for their strength, corrosion resistance, and dimensional stability. Across Riyadh, Dammam, Jubail, Jeddah, and Al-Khobar, industries rely on Cast Flange in Saudi for plumbing, wastewater, oil & gas, HVAC, and process piping systems.
A Cast Flange, produced by pouring molten metal into molds, creating a shape that matches the required dimensions and pressure ratings. This casting method results in a dense, uniform flange structure capable of withstanding internal pressures and external loads. It widely available in cast iron (CI), ductile iron, and cast steel grades, depending on the operating environment.
Common types include:
Cast Iron Closet Flange (used in plumbing and toilets)
Twist-and-Set Toilet Flange (easy installation in drain lines)
Reducing Companion Flange (for joining different pipe sizes)
High Strength: Built from cast materials that ensure durability and stability.
Versatile Design: Compatible with ASME, ANSI, BS, and DIN standards.
Corrosion Resistant: Suitable for both industrial and water service pipelines.
Cost-Effective: More affordable compared to forged flanges.
Smooth Finish: Machined sealing surfaces ensure tight, leak-free connections.
Easy Installation: Perfect for pipelines requiring periodic maintenance or replacements.
Water Supply & Drainage Systems: Used in water treatment and sewage lines.
Plumbing Installations: Ideal for cast iron closet flanges and toilet fittings.
Oil & Gas Facilities: Connects cast piping systems safely.
HVAC & Cooling Systems: Provides reliable sealing for temperature control pipelines.
Industrial Machinery: Commonly used in pumps, valves, and air compressors.
Construction Projects: Integrated into concrete slabs and underground piping layouts.

1) What is a Cast Flange used for?
It connects pipes, valves, or fittings in water, gas, and industrial systems securely.
2) What are the material options for Cast Flanges?
You can choose from cast iron, ductile iron, or cast steel based on pressure and temperature requirements.
3) What are the standard pressure ratings?
Typical classes include ASME 125, 150, and 300, depending on material strength.
4) Can Cast Flanges be used underground?
Yes. With epoxy or galvanic coating, they perform well in buried or damp conditions.
5) What is the difference between a cast and forged flange?
Cast flanges are made by molding molten metal, while forged flanges are compressed from solid metal. Cast ones are more economical for moderate pressures.
6) Are Cast Iron Closet Flanges available?
Yes—these used in toilet and sanitary installations for durable pipe-to-drain sealing.
