Unequal Crosses

Unequal Crosses are specialized four-way glass pipeline fittings where one or more branches differ in nominal diameter (DN). These fittings are designed to manage flow distribution, branching, or merging between pipelines of different sizes while maintaining chemical resistance, transparency, and vacuum compatibility.

Manufactured from borosilicate glass 3.3, unequal crosses from Bhanu Scientific Glass Co. are widely used in chemical, pharmaceutical, and process industries where varying flow rates, pressure balancing, or staged process connections are required.

How Unequal Crosses Work

An unequal cross connects four pipelines, but not all branches are the same size. This allows:

• Flow splitting from a main line to smaller branches
• Flow collection from smaller lines into a larger header
• Controlled distribution without additional reducers

The transparent glass body enables real-time monitoring of:

• Flow direction and rate
• Phase separation or mixing
• Fouling, blockage, or air entrainment

Design & Construction

• Four-way cross with different DN branches
• Precision flame-worked joints for smooth transitions
• Uniform wall thickness based on DN selection
• Stress-relieved through controlled annealing

The geometry is optimized to reduce turbulence and avoid sharp flow restrictions, even where diameter changes occur.

FAQs

Q1: When should I choose an unequal cross instead of an equal cross?
When your process requires different flow rates or pipe sizes at each branch.

Q2: Can unequal crosses handle vacuum operation?
Yes, they are suitable for full vacuum service, subject to DN and design limits.

Q3: Are custom DN combinations possible?
Absolutely. We fabricate unequal crosses as per customer drawings or process needs.
