Product ID: 05144753 – Pin Bolt Stud

Description:
This component is a pin bolt stud, a high-strength fastening element designed for use in high-pressure waterjet intensifier pumps. It is typically employed as a structural tension stud, often featuring a specialized geometry (such as a hollow design) to withstand the extreme tensile loads generated during pump operation. It serves as a critical connector, securing and aligning major assemblies such as the high-pressure cylinder, end flanges, and sealing head. The product weight is approximately 0.784 lbs.

Applications:

• Used to secure the high-pressure cylinder "jug" and end flanges to the hydraulic cylinder head in intensifier pumps.

• Acts as a locating and mounting pin, ensuring precise alignment between the sealing head and the high-pressure cylinder.

• Suitable for ultra-high pressure waterjet systems, typically operating at pressures up to 60,000 PSI (approximately 4,137 bar) and higher.

• Compatible with KMT SL-IV, SL-V, and other standard intensifier assemblies.

Features:

• High-Strength Construction: Manufactured from heat-treated alloy steel or hardened stainless steel to provide exceptional tensile strength and fatigue resistance under extreme pressure cycling.

• Precision Tolerances: CNC-machined to exact specifications to ensure a perfect fit, uniform load distribution, and consistent alignment of critical pump components.

• Structural Integrity: Engineered to maintain preload and clamping force, preventing loosening or separation of the cylinder assembly during high-frequency operation.

• Corrosion Resistance: Surface finished (e.g., polished or plated) to resist galling and corrosion from water and hydraulic fluid exposure.

Maintenance:

• Inspection: During pump overhaul, inspect studs for signs of thread damage, stretching, corrosion, or cracking. Even minor thread deformation warrants replacement.

• Replacement Schedule: It is recommended to replace pin bolt studs as a set during major rebuilds. Reusing stretched or worn studs can compromise clamp load and lead to high-pressure leaks.

• Lubrication: Apply anti-seize compound or high-pressure thread lubricant to the threads during reassembly to prevent galling and ensure accurate torque application.

• Torque Compliance: Tighten stud nuts to the specific torque values listed in the equipment service manual using a staggered (cross) pattern to ensure even clamping force distribution.

• Full Depressurization: Always fully depressurize the waterjet system, shut off the low-pressure water supply, and follow lockout/tagout safety rules before removing or installing the studs.

• Handling: Use the studs as leverage points to assist in rotating the HP cylinder jug during disassembly, but avoid damaging the threads.
