Product Name: Sand Valve Connect Pipe / Abrasive Delivery Line (Part No. 520001263)

Description:
This component is a Connect Pipe, also known as an abrasive delivery line or sand valve outlet fitting, specifically designed for the abrasive metering system of a waterjet cutting unit . It functions as the critical conduit that transfers the abrasive (typically garnet) from the output of the sand valve directly to the mixing chamber inlet on the cutting head. Constructed from a flexible, wear-resistant material such as reinforced rubber or polyurethane, this pipe allows the cutting head to articulate and move freely while maintaining a consistent, unobstructed flow of dry abrasive .

Applications:

• Transports dry abrasive from the sand valve regulator to the cutting head mixing chamber.

• Provides a flexible pneumatic connection for the motion axes (Z-axis and 5-axis tilting heads).

• Suitable for ultra-high pressure waterjet systems (compatible with 60,000 PSI / 4,137 bar operation) .

Features:

• Abrasion Resistance: Manufactured from durable materials to withstand the constant scouring of high-velocity garnet particles .

• Flexible Design: Allows for the dynamic movement of the cutting head without kinking or cracking, ensuring continuous feed.

• Airtight Construction: Prevents moisture ingress and maintains the necessary pneumatic seal for the Venturi abrasive suction effect.

• Connector Compatibility: Fittings are designed to securely connect the abrasive outlet (metering pin housing) to the cutting head body .

Maintenance:

• Visual Inspection (Daily): Check the tube for signs of external wear, chafing against the machine casing, or cracking due to flex fatigue.

• Flow Check: If the abrasive supply stops during cutting (dry cutting), this tube is a primary suspect. Disconnect the pipe and blow compressed air through it to check for blockages caused by moist or impacted abrasive .

• Leak Detection: Look for abrasive dust accumulating around the fitting connections. This indicates the tube is not sealing properly against the barbed fittings or that the pipe has worn thin.

• Preventive Replacement: It is good practice to replace the abrasive delivery pipe during annual machine servicing, as internal wear can occur without visible external damage.

• Full Depressurization: Before disconnecting the pipe, shut down the high-pressure pump, close the abrasive hopper valve, and relieve any residual air pressure in the abrasive delivery line.
