O.D. 3-3/8", Thread Type 2-13/16"-6Acme-2G, Bottom Sub for Perforating Guns
Material
This bottom sub is built with top-grade alloy steel that has been chosen based on higher strength and wear-resisting properties. The steel goes through rigorous heat treatment that enhances the hardness of the steel and the life of the part against abusive downhole environments. The rugged and hard material resists the part weakening and compromising strength and operation during abusive pressures of the perforating operation.

Production Processes
The O.D. 3-3/8" Bottom Sub has been made with a set of careful processes that help it be of the highest standards of quality:
1. Forging: The manufacturing starts with the forging of good-quality alloy steel into the original shape with a good strength of the structure.
2. CNC Machining: The sub is machined with the help of sophisticated CNC machines that conform to strict dimensional standards to fit perfectly with the rest of the perforating tools.
3. Thread Cutting: The 2-13/16"-6Acme-2G threading is correctly cut into the part with the rest of the perforating gun fragments.
4. Heat Treatment: The lower sub subsequently receives a heat treatment after machining in order to enhance hardness and fatigue strength required within the abusive perforating environment.
5. Surface Finishing: The sub receives a final surface fining treatment of removing any deficiencies and smoothing it and making it rugged.
Quality Test & Inspection
The O.D. 3-3/8" Bottom Sub undergoes a rigorous testing and inspection program to ensure the highest level of reliability and performance:
• Dimensional Verification: The threading and O.D. dimensioning are examined with the aid of highly developed measuring instruments in accordance with the required standards.
• Pressure Testing: The lowermost sub is pressurized at a higher-than-normal pressure so that it will not collapse during the perforating operation.
• Material Quality Testing: The steel’s hardness, tensile strength, and resistance to corrosion are rigorously tested to confirm its durability.
• Thread Quality Inspection: Thread strength and stability are examined with specialized tools to allow a tight fit and firm engagement during operation.
Key Features
• Durability: Constructed with a heavy duty heat-treated steel that ensures superior strength and durable operation in harsh environments.
• Precision Threads: 2-13/16"-6Acme-2G thread will fit tight with a firm fit that will leave a tight and leakage-proof seal.
• Pressure and temperature resistance: Constructed to be resistant against high-temperature and high-pressure environments normally found during perforating gun operation.
• Custom Length Availability: Offered in a variety of lengths that suit the specific customer needs of perforating gun assembly.
Industry Applications
The O.D. 3-3/8" Bottom Sub is mainly used in the oil and gas industry, specifically in perforating gun systems for well completion. Key applications include:
• Perforating Operations: The company has a good tie in perforating guns that play a vital role in creating openings within the casing of the wells utilized in the recovery of oils and gasses.
• Well Stimulation: Used in well stimulation processes, the sub ensures efficient and reliable perforation for fracturing or acidizing treatments.
• Hydraulic Fracturing: An integral part of hydraulic fracturing, enabling safe and efficient perforation for effective fluid flow.
Packaging and Storage
The O.D. 3-3/8" Bottom Sub has cautious shipping that will not subject it to mishandling and shipping damage. The sub is warehoused in a clean and dry environment that will keep it free of any environment-induced degradation that will cause rusting. Proper storages and handling of the sub will take it to the installation site in the working and operational position.
Shipment
Once the sub has undergone the tests of quality checks, it is packed and sent with good shipping methods with the option of trackability so that we know it reaches you in good condition. The package has been specially made so that the O.D. 3-3/8" Bottom Sub does not get damaged in the shipping and reaches you perfectly fine and in working condition for use in the operation of perforating.
