O.D. 3-1/8", Upper/Lower Thread Type 2-3/4"-6Acme-2G, Tandem Subs for Perforating Guns
Material
Crafted with the highest strength alloy steel with use, the 3-1-1/8" O.D. tandem subs are built with the harsh environments of the environment of the oil and gas wells in mind. The material that has been used has superior wear and corrosion resistance and will keep the subs operational throughout the subs' life cycle. The material also has an additional specialized heat treatment that further enhances strength and ensures the subs' strength at higher temperatures and pressures.
Specifications
• Outer Diameter (O.D.): 3-1/8 inches with a heavy duty and versatile design suitable for a multitude of perforating gun uses.
• Thread Type: 2-3/4" lower and top 6Acme-2G threading that will be tight and will enable smooth torque flow during operation and deployment.
• Material: Made of highest-quality alloy steel that provides the subs with lasting strength and abusive environment resistance.
• Pressure Rating: Constructed to bear the heavy-pressuring conditions of the usual deep-well application.
• Length: Customized according to the individual needs of the perforating systems with flexible design of the perforating gun assembly option.

Production Processes
The Tandem subs are produced in a series of highly detailed processes to make each part of the highest standards of the industry:
1. Material Selection & Forming: The highest-quality alloy steel comes into the picture and it is forged in the original sub shape.
2. Precision Machining: The subs are machined with great accuracy in the 2-3/4"-6Acme-2G threads such that they fit perfectly with the required specification.
3. Heat Treatment: The subs get a heat treatment that increases hardness and attains wear and tear resistance during operation.
4. Thread Cutting & Polishing: Following the machining operation, the threading is accurately cut and polished in a manner that ensures a smooth and fine surface with low friction and highest strength.
5. Inspection & Quality Check: The last item receives thorough checks of the strength of the thread, strength of the structure and compatibility with the remaining perforating gun components.
Quality Test & Inspection
The Tandem Sub also goes through strict testing against strict standards of safety and performance:
• Thread Accuracy Test: The Acme-2G threads shall be properly cut and spaced with a good fit that will allow a tight grip during the perforating operation.
• Pressure Resistance Test: The subs are subjected to modeled high-pressure testing to verify that they will perform reliably and last in actual field-downhole environments.
• Material Testing: The alloy steel is checked for strength, ensuring the sub can withstand high-stress applications without failure.
• Surface Quality Inspection: The subs are also tested against surface faults that will influence the operation of the subs and induce premature wear during use.
Key Features
• Secure Threading: 2-3/4"-6Acme-2G threading will provide a tight and tight fit and a good tight fit between sections of a perforating gun.
• High Durability: The strength steel alloys used in subs demonstrate excellent wear and corrosion resistance even in harsh well environments.
• Pressure and temperature resistance: Well-suited for operation at high temperatures and pressures and therefore appropriate for use in deep wells.
• Efficient Assembly: The properly machined threading permits smooth and speedy mounting and dismounting with minimal maintenance downtime.
• Long-Lasting Performance: Heat-treated to sustain multiple cycles of perforating with a long working life.
Industry Applications: The 3-1/8" O.D. tandem subs serve a vital role in a variety of oil and gas applications, including:
• Perforating Gun Components: They are used in assembling the diversified sections of the perforating gun with a stable and firm charge installation.
• Well Completion and Stimulation: Essential in the development of stable perforations in the casing that allow free flow of fluids in the horizontal and vertical wells.
• Hydraulic Fracturing: The subs play a critical part in fracking processes, providing a smooth operation of the perforating guns during the fracturing operation.
• Geothermal Applications: They're also trustworthy in the higher-temperature environment and therefore geothermal-compatible perforations.
Packaging and Storage
The Tandem Subs are packed with a great deal of care so that they don't get damaged during shipping and storage. They are packed within a shock-resistant package that won't cause surface scratches and distortion of the thread. They should be placed in a cold and dry place so that they don't rust. The package includes clear labels that allow them to be identified with ease.
Shipment
Each of the Tandem Subs ships in rugged and secure containers that avoid any damage during shipping. The subs ship per industry standards of safety and include shipping and receiving track and trace with the customer. Great care is provided in shipping the subs so that they arrive in top-notch condition and are good to use immediately at the receiving site.
