Sanitary Stainless Steel Pin Fixed Spray Ball

The Stainless Steel Sanitary Pin-Fixed Spray Ball is a static spray device designed for the internal cleaning of tanks and vessels. Its defining feature is its pin-type quick-assembly structure; by combining the corrosion resistance of stainless steel with the precise, targeted spraying of fixed spherical nozzles, it offers a cost-effective and easily disassembled tank cleaning solution for industries such as food processing, pharmaceuticals, and chemicals.

**Core Structure and Materials**

This spray ball is specifically engineered for high-sanitation environments, featuring meticulous design in both materials and structure: **Body Material:** Typically constructed from SUS304 or SUS316L stainless steel. SUS316L is frequently utilized in pharmaceutical and chemical applications due to its superior resistance to acids, alkalis, and high temperatures. **Surface Finish:** Both internal and external surfaces undergo mirror polishing to achieve low surface roughness; this minimizes dirt accumulation and ensures compliance with sanitary certification standards such as GMP and FDA. **Connection Method:** The core feature is the pin-type connection, which enables rapid assembly and disassembly without the need for tools—a design that can boost maintenance efficiency by over 80% compared to threaded or welded connections.

**Working Principle**

The fixed spray ball operates as a static device, containing no internal rotating components. During operation, high-pressure cleaning fluid (such as water or disinfectant solutions) enters the spherical body and is ejected directly through small, pre-angled orifices on the surface. This creates fan-shaped or conical fluid streams that directly scour the interior walls of the tank.

**Spray Patterns:** Standard models typically offer either 360° full coverage or 180° directional spraying.
**Coverage Range:** A single spray ball typically achieves a cleaning radius of 1.25 to 5 meters, depending on the operating pressure and flow rate.

**Product Advantages**

**Rapid Assembly/Disassembly:** This is the most significant advantage of the pin-type design compared to other connection methods. The pin connection requires no wrenches, making it ideal for high-sanitation environments where frequent removal and cleaning of the spray ball body are required.
**Zero Maintenance Costs:** Since there are no moving parts—such as bearings or impellers—there is no risk of mechanical wear; the device is virtually maintenance-free and boasts an extremely low failure rate.
**Precise Cleaning:** The angles and positions of the spray orifices are fixed, ensuring a stable and controllable spray trajectory that facilitates customized designs to effectively target and clean "dead spots" or hard-to-reach areas within the tank. Temperature and Corrosion Resistance: Its all-stainless steel construction enables it to withstand high temperatures ranging from 120°C to 200°C, and to endure operating pressures of 0.3 to 1.0 MPa.

Common Technical Parameters

Dimensions: The connection pipe diameter typically ranges from DN15 to DN65 (approximately 1/2 inch to 2.5 inches).
Operating Pressure: A range of 1.5 to 3 bar is recommended, as cleaning efficiency is optimal within this range.
Flow Rate Range: Approximately 12 to 38 m³/h; for certain models, the flow rate can reach up to 330 L/min at a pressure of 2 bar.
Maximum Temperature Resistance: Standard models can withstand temperatures up to 120°C; when equipped with specialized seals and structural components, they can endure temperatures of 200°C or even higher.
