Precision Manufacturing and Design

Double Flanged Reducers are designed to stringent standards, ensuring consistent face-to-face distances and precise hole drilling according to EN 1092-2 and BS 4504. This attention to detail, along with hydraulic and dimensional inspection, provides reliability and ease of installation in demanding pipeline environments.

Versatile Application and Robust Performance

Offering compatibility with a wide range of pipe sizes and systems, these reducers are ideal for water distribution, sewage lines, and industrial pipelines. Their rigid construction and gasket sealing ensure minimal maintenance and long-term durability even under high pressures and varying temperatures.

High Corrosion Resistance and Quality Assurance

An epoxy-coated surface delivers exceptional protection against corrosion, ensuring longevity in harsh conditions. Each reducer undergoes thorough hydraulic and dimensional inspection, meeting tolerance requirements and guaranteeing consistent product quality.

FAQ's of Double Flanged Reducers:

Q: How are double flanged reducers installed in pipelines?

A: Installation involves bolting the reducer between two flanged pipes using gaskets for sealing. The process requires alignment as per the drilled holes (EN 1092-2/BS 4504) and tightening to specification, ensuring a secure fit for reliable operation.

Q: What applications are double flanged reducers best suited for?

A: These reducers are widely used in water supply systems, sewage networks, and industrial piping where pipes of different diameters need to be connected securely while maintaining pressure integrity and preventing leaks.

Q: When should a concentric versus an eccentric reducer be used?

A: A concentric reducer is ideal when the centerline of the piping must remain consistent. Eccentric reducers are preferred where drainage or air accumulation is an issue, such as on horizontal pipelines to prevent pooling or air pockets.

Q: What quality inspections are performed on these reducers?

A: Each reducer undergoes hydraulic pressure testing at up to 1.5 times the rated pressure, along with dimensional inspection to ensure compliance with standards and a tolerance of 1 mm for precision fitment.

Q: Where does the corrosion resistance come from in these reducers?

A: The reducers are epoxy coated using a fusion-bonded process, providing high resistance to corrosion. This makes them suitable for harsh environments and extends their operational lifespan.

Q: What are the packing and shipping options for double flanged reducers?

A: Reducers are carefully packed in wooden crates or poly wrap to protect them during shipping and storage, ensuring they arrive in optimal condition for installation on-site.
