Production Processes
The O.D. 4-1/2" Bottom Sub is produced through a series of well-controlled processes to meet industry standards:
1. Forging: Initially forged with top-grade alloy steel in order to build a strong foundation of the part.
2. CNC Machining: CNC machined with great precision to the required dimension and thread specification. The machining guarantees smooth fitting with the rest of the perforating gun assemblies.
3. Thread Cutting: The 3-15/16"-6Acme-2G threads are professionally cut into the sub so that the connections will be smooth and leakage free and tight.
4. Heat Treatment: The lower sub also receives a heat treatment that maximizes strength and wear and fatigue resistance in an effort to perform effectively in a highly stressing environment.
5. Surface Finishing: The sub is also smoothened during the surface finishing and this avoids wear and tear and enhances the surface strength against harsh working environments.
Quality Test & Inspection
Every O.D. 4-1/2" Bottom Sub has undergone exhaustive testing to meet the highest standards of safety and quality. The testing includes:
• Dimensional Check: The individual part goes through rigorous measuring to ensure that it adheres to the required standards of the thread pitch and the external diameter.
• Pressure Testing: The sub is pressurized with artificial pressurization testing such that it will be able to bear the stresses of the perforating operation.
• Material Testing: The tensile strength and hardness of the steel alloy are subjected and assured against the harsh operation standards required.
• Thread Integrity: Threads are scrutinized closely with respect to consistency and accuracy in an effort to enable correct fitting and leakage-proof fit in the field.
Key Features
• Robust Construction: Made of heat-treated steel alloys that promise stronger and lasting construction.
• Precision Threads: The 3-15/16"-6Acme-2G thread design ensures a tight, secure connection with other perforating tools, preventing leaks.
• High-Pressure and Temperature Resistance: Designed to operate at the elevated pressure and temperature environments normally found during the course of oil and gas wellbore activities.
• Customizable Length: Specially designed for particular perforating gun systems with the provision of variability for varied well-completion requirements.
