O.D. 2", Upper/Lower Thread Type 1-11/16-8 STUB ACME-2G, Tandem Subs for Perforating Guns
Material
The Tandem Subs are made of high-strength alloy steel that has been chosen specifically for withstanding the harsh downhole environments of high temperatures, pressures, and corrosivity. The subs' strength and stability throughout the entire perforating operation are assured with this material that resists failure and damage. The subs' threads are machined with great attention to the specifications of the required tight and leakage-proof connections. The subs' material also receives wear-resistant treatment so that they last longer.
Specifications
• Outer Diameter (O.D.): 2 inches with a firm and tight fit that will be compatible with a variety of perforating gun systems.
• Thread Type: 1-11/16-8 Stub ACME-2G lower and top with a design that will be appropriate for firm and torque-intensive application.
• Thread Design: The increased strength and wear resistance of the STUB ACME design prevent wear of the thread during operation and installation.
• Length: The sub has been specially set with the required length of the connection to fit comfortably into the perforating gun system.
• Pressure Rating: Built to withstand high pressure, making it suitable for deep well perforations and high-stress environments.

Production Processes
The tandem subs' manufacturing involves a cautious and multi-step process that ensures that each part achieves the highest standards of the trade
1. Material Selection and Forging: The highest strength and resilience are assured with the specially selected premium alloy steel forged into the foundation shape of the sub.
2. Precision Machining: The part goes through detailed machining in an effort to create the highly complex thread forms and fit perfectly with the rest of the members of the perforating gun system.
3. Heat Treatment: The sub receives a heat treatment that hardens it and resists wear and tear and will be able to perform at temperature and pressure.
4. Thread Cutting: The cutting of the STUB ACME threads with the latest technology guarantees a smooth fitment and engagement.
5. Finishing & Polish: The sub also receives fine-punching and a polish that lower the friction and maximize the working of the sub during operation.
Quality Test & Inspection
Quality testing and inspection of each and every Tandem Sub guarantees that it adheres to rigorous standards of quality:
• Thread Inspection: The threads of the part are examined for dimension and consistency to allow smooth and leakage-proof connections and correct fitting.
• Pressure Testing: The subs are subjected to a high-pressure testing so that they may be assured of withstanding the rugged environment of the deep-well operation.
• Material Integrity: Each batch of subs is tested for material strength, ensuring that the alloy steel used meets the required standards for high-performance use.
• Surface Finishing Inspection: This ensures that the surface has no defects and smooth enough to reduce the friction during operation.
• Functional Testing: The functional testing of every sub guarantees that it will correctly perform once it has been integrated within the perforating gun system.
Key Features
• Durability: Constructed with rugged high-strength alloy steel that has good strength and resilience at elevated temperatures and pressures.
• Precision Threading: The 1-11/16-8 STUB ACME-2G threading ensures a tight and firm fit that enhances the consistency of the connections.
• Pressure Resistance: Built to withstand high pressure, ensuring safety and performance in deep-well operations.
• Easy Maintenance: Simple and uncomplicated installation and removal with easy maintenance and easy replacements.
• Long Lifespan: The alloy steel construction and heat treatment ensure that the subs last longer, reducing the need for frequent replacements.
Industry Applications
The O.D. 2" tandem subs with the application of the STUB ACME-2G threads get utilized in a variety of petroleum and natural gas sector perforating activities including:
• Perforating Gun Units: They comprise an integral unit of the assembling that maintains tight connections among the sections of the perforating gun.
• Downhole Well Completion: Used to connect various components of the perforating guns, enabling the successful detonation of explosive charges for well stimulation.
• Hydraulic Fracturing (Fracking): The subs are perfectly suitable for fracking activities with the need of making fine and reproducible perforations in order to maximize the flow of fluids and proppant.
Packaging and Storage
Each Tandem Sub is carefully packaged to ensure it remains in perfect condition during transportation and storage. The subs are sealed in protective packaging to prevent any damage from external factors, and each unit is labeled for easy identification. Storage should be in a dry, cool area to prevent rust or corrosion. Proper handling during storage will also ensure that the threads are not damaged, preserving the integrity of the component.
Shipment
Tandem Subs are shipped in compliance with industry regulations for hazardous materials, ensuring safety throughout transit. Each unit is securely packed in durable packaging to prevent any damage during shipment. Customers will receive tracking information for real-time updates, ensuring a smooth and reliable delivery process.
