A-Type Long Nozzle

A-Type Long Nozzle – Extended-Reach, High-Penetration Jetting Nozzle for Deep Cavity Cleaning, Confined Space Descaling, and Industrial Maintenance in Hard-to-Access Areas

In industrial maintenance and cleaning operations—where access depth, jet coherence, and erosion resistance determine success—the A-Type Long Nozzle is engineered to deliver high-velocity fluid streams deep into confined or narrow spaces that standard nozzles cannot reach. From reactor internals in Saudi petrochemical plants to heat exchanger tube bundles in UAE power stations, boiler fireboxes in Qatari utilities, and pipeline pig traps across Oman, this extended-reach nozzle maintains precise jet directionality and impact energy over lengths up to 2,000mm, enabling effective cleaning without dismantling equipment or risking personnel in hazardous zones. At Qalalam Industrial Supply, our A-Type Long Nozzles are precision-machined from stainless steel 316L or tungsten carbide, ensuring structural rigidity, corrosion resistance, and long service life in high-pressure, high-temperature, and abrasive-fluid environments across the GCC.

Unlike makeshift extensions or flexible lances that deflect, leak, or lose pressure, the A-Type Long Nozzle features a monolithic, straight-body design with optimized internal flow paths that minimize turbulence and pressure drop—delivering consistent cleaning performance from tip to base. Whether used for manual descaling, robotic cleaning, CIP (Clean-in-Place) systems, or emergency decongestion, this nozzle provides the reach, reliability, and durability that maintenance teams in the Middle East depend on.

Design Philosophy: Reach Without Compromise

The “A-Type” designation refers to a slender, straight, rigid profile optimized for:

• Deep penetration into cavities, tubes, or vessels
• Minimal external diameter to fit through small access ports (as small as 25mm)
• Reinforced wall thickness to resist buckling under high pressure
• Precision-machined tip for focused jet patterns (full cone, flat fan, or straight jet)

Critical innovation: Internal flow channels are polished to Ra ≤ 0.8µm—reducing friction loss and maintaining >90% of inlet pressure at the tip, even at 1.5m length.

All nozzles are stress-relieved after machining to prevent warping under thermal cycling.

Key Technical Features

• Length Range: 300mm to 2,000mm (standard), up to 2,500mm (custom)
• Outer Diameter: 10mm to 25mm (to fit standard access ports)
• Inlet Connection: 1/4″ to 1″ BSP/NPT (male or female)
• Tip Configurations:
  • Straight Jet (0°): For deep penetration, hole drilling
  • Flat Fan (15°–60°): For wall washing, surface cleaning
  • Full Cone: For volume coverage in chambers
• Wall Thickness: 2.0–4.0mm (optimized for pressure vs. flexibility)
• Straightness Tolerance: ≤ 0.1mm per 500mm length

🔧 Critical detail: For lengths >1,000mm, we use double-supported grinding to ensure the nozzle doesn’t sag during use—maintaining accurate jet targeting.

Customization: Built for Your Access Constraints

We specialize in custom A-Type Long Nozzles:

• Bent Tips: 15°, 30°, or 45° for corner cleaning
• Multi-Orifice Tips: For wider coverage in large chambers
• Reinforced Mid-Sections: For high-vibration environments
• Quick-Connect Ends: For rapid tool changes
• Laser Marking: Length, material, and part number

💡 Pro Tip: For lengths >1,500mm, we recommend dual support brackets during operation to prevent vibration—but the nozzle itself remains rigid and self-supporting.

Why Qalalam? Precision Reach, Local Support

• Only UAE supplier with 2.5m-capable grinding
• In-house pressure and flow testing—every nozzle validated
• Field-tested in GCC harsh environments
• Bulk pricing with next-day delivery for common sizes

We don’t just sell nozzles—we extend your cleaning reach without compromise.

Frequently Asked Questions (FAQs)

Q1: What’s the maximum length you can produce while maintaining rigidity?
A: 2,000mm with ≤0.4mm deflection under 500 bar—achieved through thick-wall design (3–4mm) and stress-relieved material. For 2,500mm, we use larger diameter (25mm) to maintain stiffness.

Q2: Can your long nozzles be used with standard high-pressure pumps?
A: Yes. Our nozzles are designed for common industrial pressures (70–2,500 bar). Just match the inlet thread (we offer BSP, NPT, metric) and flow rate (we provide performance curves).

Q3: How do I prevent the nozzle from getting stuck in a deep cavity?
A: We recommend:

• Smooth external finish (Ra ≤ 0.8µm) to reduce friction
• Tapered tip for easier insertion
• Guide bushing at the access port
• Retractable lanyard (optional)
  Most users find the rigid design actually reduces sticking vs. flexible lances that kink.

Q4: Are your nozzles suitable for food or pharmaceutical cleaning?
A: Yes. Our SS 316L nozzles are:

• Electropolished (Ra ≤ 0.4µm)
• Passivated per ASTM A967
• Compliant with 3-A, FDA 21 CFR, and EHEDG
  Used in long-reach CIP for bioreactors and mixers.

Q5: Can you add side jets for 360° cleaning in tubes?
A: Yes—our A-Type Multi-Jet variant includes radial orifices along the last 100mm for full tube coverage. Ideal for heat exchanger bundle cleaning.

Q6: What’s your lead time for a custom 1,800mm nozzle?
A: 5–7 days for SS 316L from Dubai. 10 days for carbide or Inconel. We keep standard lengths (500–1,500mm) in stock for next-day delivery.

Q7: Do you offer nozzle inspection or refurbishment services?
A: Visual inspection: free. Re-tip or re-thread: yes—if the body is intact. However, due to high performance-to-cost ratio, most customers replace rather than refurbish.
