O.D. 3-3/8", Upper/Lower Thread Type 2-13/16"-6Acme-2G, Tandem Subs for Perforating Guns
Material
The 3-3/8" tandem subs are made of highly strength alloy steel that has been specially selected with a focus of giving the highest strength and resistance against harsh temperature and pressure. The steel undergoes a rigorous heat treatment that enhances the hardness and strength of the subs in such a manner that the subs can tolerate the harsh environment of the deep oil and gas wells. The steel also has wear and corrosion resistance and fatigue that enhance the life of the subs and minimize the probability of the subs failing in operation.
Specifications
• Outer Diameter (O.D.): 3-3/8 inches with a rugged and stable construction that will accommodate a multitude of configurations of perforating guns.
• Thread Type: The 2-13/16" and top 6Acme-2G with a tight and firm fit that will enable a stable and tight fit and smooth torque transition.
• Material: Made of higher strength steel alloy with hardness and rust-resistant properties.
• Pressure Rating: Designed to operate within highly pressurized environments of deep-well application.
• Length: Customizable depending on the diversified needs of perforating guns and appropriate fitment within the assembly

Production Processes
The Tandems are manufactured in a multi-step operation in a bid at bringing consistency and accuracy:
1. Material Forging: The high-strength alloy steel is forged into the rough shape of the sub, ensuring the material retains its integrity.
2. Precision Machining: The subs get machined perfectly to specification and the 2-13/16"-6Acme-2G threads get machined so that they provide a smooth fit with minimal wear and friction.
3. Heat Treatment: The subs receive a heat treatment that enhances hardness and resistance against high-temperature environments and ensures that they perform in harsh environments.
4. Threading and Polishining: The threads are properly machined and polished during machining in a way that ensures smooth operation and long life during usage.
5. Quality Assurance: Stringently tested and proven, each sub complies with the highest standards of performance and quality.
Quality Test & Inspection
The subs get properly tested and of the highest standards of quality
• Thread Integrity Test: The threads are checked for accuracy to ensure they meet the exacting standards required for secure and efficient connections.
• Pressure Testing: The subs are subjected to pressurization tests in an attempt to keep them within real-downhole environments.
• Material Quality Inspection: The strength and corrosion resistance of the alloy steel are tested to be able to sustain harsh well environments within the sub.
• Surface Examination: Stringent examinations protect the sub against faults that will diminish the sub's performance or the life of the sub.
Key Features
• Durable Design: The tandem subs of O.D. 3-3/8" use rugged and heat-treated ally steel that resists excellent strength and durable use.
• Acme-2G Threads: The 2-13/16"-6Acme-2G threading provides a tight and leakage-tight fit and smooth torque transition between sections of perforating guns.
• High Pressure Resistance: They bear a great pressure and therefore suit the application of the deep wells.
• Corrosion-Resistant: The resistance of subs against corrosion ensures that they will be operational in aggressive and harsh chemical environments reliably.
• Customizable Lengths: The subs may be specially made with the specific application of the perforating gun system and enable flexible assembling.
Industry Applications
The 3-3/8" tandem subs are applied in a variety of critical petroleum and natural gas applications
• Perforating Guns: An integral part of the assembling of the perforating gun that provides a stable and strong interface between the sections of the gun.
• Well Completion: Utilized in making stable perforations in the casing that allow good flow and allow the well to be effectively stimulated.
• Hydraulic Fracturing: Is a critical aspect of the fracking operation that ensures the perforating guns function properly during the operation of fracturing.
• Deep Well Drilling: They can be applied in drilling of the deep wells because they also possess the strength against temperatures and pressures and also in risky environments.
Packaging and Storage
Care has been taken in the packaging of the Tandem subs so that they will not be damaged during shipping. Individual subs are sealed in a protecting package so that they will arrive with the assurance of their integrity intact. The subs will be stored in a temperature-controlled and a dry place to avoid any corrosion. Handling and careful storage will prolong the life of the subs.
Shipment
These Tandem Subs ship in heavy duty, tamper-resistant containers that will keep them in great shape at the receiving end. Tracking codes with each purchase allow the customer to track the status of the shipment. The subs ship with great care and attention paid to minimize any chance of them being damaged during shipping and arrive quickly and safely at the customer’s door.
