Modular Pipework Fittings: Branches, T-Pieces, and Inspection Pipes
.
BritSOLIDS provides a comprehensive range of precision-engineered Modular Pipework Fittings designed to integrate seamlessly into any lipped-end tubing system. From diverting material flow to providing essential maintenance access, our fittings are the industry standard for bulk solids handling and industrial extraction in the UK.

Optimised Flow: Branch & Y-Pieces

JACOB modular piping system
In Pneumatic Conveying and Gravity Fall systems, the geometry of a branch is critical. A poorly designed T-piece creates turbulence, material “hang-up,” and excessive wear. Our fittings are engineered with smooth internal transitions to maintain constant velocity.
- Symmetric Y-Pieces (Trouser Pieces): Ideal for splitting a single flow into two equal streams in gravity-fed systems.

- Lateral Branches (30° and 45°): The preferred choice for extraction headers. The shallow angle reduces back-pressure and minimizes the risk of blockages compared to 90° entries.
- T-Pieces (90°): Standard connectors for air distribution and low-velocity ventilation lines.

Essential Maintenance: Inspection & Cleaning Pipes

UK safety and hygiene standards (such as HACCP and COSHH) require regular internal inspection of process lines. Our Inspection Pipes allow for rapid access without dismantling the entire run.
- Inspection Pipes with Cleaning Hatches: Feature a secure, bolted, or quick-release cover with a food-grade seal. Perfect for clearing blockages in “sticky” powder lines.
- Observation Pipes (Plexiglass/Glass): Allow for 360° visual monitoring of the material flow. Essential for identifying feed rate issues or “slugging” in pneumatic lines.
- Tapping Points: Small-diameter ports for the installation of sensors, pressure gauges, or air-sampling equipment.

Modular Pipework Fittings – Technical Specifications & Build Quality
All our modular fittings are manufactured to the same rigorous standards as our straight tubing:
- Wall Thickness: Available in 1mm (Ventilation/Dust) or 2mm – 3mm (Abrasive Bulk Solids).
- Construction: Laser-welded or seam-welded for maximum structural integrity.
- Materials: Carbon Steel prime-coated, Galvanised Steel for cost-effective extraction or AISI 304/316L Stainless Steel for food and pharmaceutical environments.

Technical FAQ: Modular Ducting Fittings
Q: What is the benefit of a 30-degree branch over a 90-degree T-piece?
A: In extraction and bulk handling, a 30-degree branch significantly reduces turbulence and material impact on the opposite wall of the pipe. This extends the service life of the fitting and improves overall system efficiency.

Q: Are the inspection hatches airtight?
A: Yes. Every Inspection Pipe is fitted with a high-density NBR or Silicone gasket to ensure that the system maintains its pressure or vacuum integrity when the hatch is closed.

Q: Can you provide bespoke branch angles?
A: While 30°, 45°, and 90° are our standard stock items, we can supply bespoke branch pieces to match any specific process layout.
