Component Specifications

Definition
The Main Spray Bar Pipe is a critical tubular component within spray bar assemblies, engineered to distribute liquids (such as water, chemicals, or coatings) evenly across surfaces or materials. It features precisely drilled orifices or nozzles along its length to create consistent spray patterns. This component is essential in applications requiring controlled fluid delivery, including cleaning, coating, cooling, or chemical treatment processes in various manufacturing environments.
Working Principle
Operates on fluid dynamics principles where pressurized liquid enters the pipe and is forced through strategically positioned outlets (nozzles or holes) along its length. The pressure drop across these outlets creates uniform spray patterns, with flow rate and distribution controlled by pipe diameter, orifice size, spacing, and system pressure.
Materials
Typically manufactured from corrosion-resistant materials: 304 or 316 stainless steel (most common), carbon steel with protective coatings, or specialized alloys like Hastelloy for aggressive chemical environments. Material selection depends on fluid compatibility, pressure requirements, and environmental conditions.
Technical Parameters
  • Length Custom (typically 1-6 meters)
  • Diameter 25-150 mm
  • Surface Finish Ra ≤ 1.6 μm
  • Orifice Spacing 50-300 mm
  • Pressure Rating 10-100 bar
  • Orifice Diameter 0.5-5 mm
Standards
ISO 1127, DIN 2448

Frequently Asked Questions

What factors determine the spacing of orifices on a main spray bar pipe?

Orifice spacing is determined by required spray coverage, liquid properties, pressure, and application specifications. Closer spacing provides more uniform coverage but requires higher flow rates.

How do you prevent clogging in spray bar pipes?

Regular maintenance, filtration of incoming fluids, using appropriate orifice sizes, and selecting corrosion-resistant materials help prevent clogging. Some designs include cleaning ports or removable end caps.

Can main spray bar pipes be customized for specific applications?

Yes, they are often custom-engineered with specific lengths, diameters, orifice patterns, and materials to match exact process requirements, flow rates, and spray patterns.

Can I contact factories directly?

Yes, each factory profile provides direct contact information.
