O.D. 2", Thread Type 1-11/16-8 STUB ACME-2G, Lift Subs for Perforating Guns
Material
Crafted from superior alloy steel, the Lift Sub is subjected to heat treatment to maximize the strength and wear and tear resistance of the metal. The use of alloy steel ensures it will be able to withstand the heavy pressures and abrasive forces of drilling and perforation processes. The sub is also coated with a protective overlay to shield against corrosion and perform reliably in harsh environments such as deep wells, offshore drilling and corrosive fluids.

Production Processes
The Lift Sub has a complex manufacturing system that ensures the highest standards of performance and accuracy:
1. Forging: The process starts with the forging of superior-grade alloy steel that forms the backbone of the sub. This increases the mechanical strength of the steel so that the sub will be resistant to harsh environments.
2. CNC Machining: The forged sub then goes through rigorous CNC machining, wherein it is machined into the required specification, that of the threads that play a crucial part in the operation of the sub.
3. Thread Cutting: The 1-11/16-8 STUB ACME-2G threads are subsequently cut with highly accurate cutting tools to provide a firm grip and leakage-proof connections.
4. Heat Treatment: The sub also goes through a heat treatment that increases the strength of the sub and hardens the steel against wear and fatigue.
5. Coating: A rust-resistant coating is applied to the sub so that it will be protected against rust and the harsh chemicals that normally fill the wellbore.
Quality Test & Inspection
Each Lift Sub goes through rigorous tests of quality assurance to be confirmed against industry standards:
• Dimensional Accuracy: The sub is properly measured with the correct dimensions including the thread size so that it will fit with the remaining perforating gun system pieces.
• Thread Inspection: The threads are thoroughly inspected for consistency and correct fitment so that a tight fitment will be provided.
• Pressure Testing: The sub is subjected to pressure tests that simulate actual operational environments to ensure that it has the ability to withstanding pressurized environments.
• Material Integrity: The strength, hardness, and fatigue strength of the material undergo tests and are established to be able to sustain the longevity of the sub.
Key Features
• Strong Thread Designing: The 1-11/16-8 STUB ACME-2G threading has a firm and strong fit between the per-forcement gun and the hoisting gear.
• Durable Alloy Steel Design: Constructed with rugged and heavy-duty heat-treated alloy steel that maintains superior strength and operation in harsh environments.
• Corrosion Protection: The rust and wear-resistant coating will last a long time.
• High Pressure Resistance: Design with the offshore and deep well drilling pressures in mind.
• Custom Length Capability: The custom-length design of the Lift Sub specifically caters to the individual needs of each operation.
Industry Applications
The O.D. 2" Lift Sub is utilized in a variety of oil and gas operations including
• Perforating Gun Assemblies: Essential for connecting the perforating gun to other downhole equipment, allowing safe and secure lifting and deployment.
• Drilling and Completion Operations: Crucial to the drilling and completing processes' operation of perforating guns.
• Offshore and Onshore Drilling: Well adapted to offshore and onshore drilling of natural and petroleum with heavy duty and resistant fittings utilized.
Packaging and Storage
The Lift Sub is properly packed with the motive of not causing any damage during shipping. It is typically packed with a pad of protection or a crate so that it does not get damaged during shipping. The sub should be stored in a clean and dry environment so that moisture does not cause rusting of the sub. Proper storage also maintains the surface of the sub and increases the useful life of the sub.
Shipment
After passing the assurance program of the quality tests, the customer specification based Lift Sub is sent. The customer has multiple shipping options with facilities such as shipping expedited if the customer needs it quickly. Shipping track is done so that the customer receives it in good and prompt state.
