O.D. 7", Thread Type 6-1/4"-6Acme-2G, Tie Down Subs for Perforating Guns
Material
Constructed from the highest-grade of alloy steel and subjected to a thorough heat treatment cycle, the Tie Down Sub has higher strength, wear resistance, and longevity. The metal has been specifically selected based on the strength it displays against harsh stresses and fatigue and the susceptibility it has against the corrosive fluids found in drilling of deep wells. The sub also has a rust- and environment-resistant coating applied thereto in order to maximize the sub against rust and weather degradation.

Production Processes
The manufacturing of the Tie Down Sub has a few highly-accurate processes that yield the highest-quality results:
1. Forging: The initial operation involves the forging of the highest strength alloy steel into the general outline of the sub. This operation will provide a good strength and hardness base.
2. Machining: Next, the CNC machining tools will further refine the sizes such that each part will be of the highest specification standards of 6-1/4"-6Acme-2G threads.
3. Thread Cutting: The vital Acme threads are properly cut so that they assure smooth and tight fitting with no leakage and mechanical failure.
4. Heat Treatment: The sub is heat-treated to improve its hardness and fatigue resistance, making it capable of enduring the high-pressure conditions typically found in oil and gas operations.
5. Coating: A rust-resistant coating is applied to the sub in an effort to protect it against the ruining effect of rusting chemicals and abrasives contained in the wellbore.
Quality Test & Inspection
Each Tie Down Sub goes through an exhaustive battery of tests in anticipation of public use once it has met strict standards of excellence
• Dimensional Checks: The sub is dimension-checked to assure the dimension of the thread such that it will fit with the remaining components.
• Thread Testing: The threading is tested for consistency and accuracy in an effort to ensure a tight, leakage-resistant fit.
• Pressure Testing: The subs exposed to artificial higher-than-atmospheric pressures to put it through real operational stresses.
• Material Integrity: The sub is put through tests of the material that will be capable of withstanding lasting forces and chemical aggressions.
Key Features
• Reliable Thread Interface: Fitted with 6-1-1-4" 6Acme-2G threading that provides tight and firm connections between perforating guns and the
• Durable Construction: The sub has a highly durable construction of strength alloy steel that resists stresses that appear in deep-well environments.
• Corrosion-Resistant Coating: Protected against the environment of the wellbore with harsh chemicals and corrosives with a life-extending benefit.
• High Pressure Rating: Designing with a strength that resists higher pressures and maintains the strength during prolonged usage.
• Custom Lengths: Offered in a variety of lengths to suit different operational needs.
Industry Applications
The O.D. 7" Tie Down Sub plays a critical use in the petroleum and natural gas industry specifically in
• Perforating Gun Systems: Utilized in firm fixation of perforating guns and other downhole tools.
• Deep Well Drilling: Most suitable drilling of pressurized and deep wells in nearshore and offshore environments.
• Well Completion and Workover Operations: Assures the stability of the perforating systems during completing and maintenance procedures.
Packaging and Storage
For safe shipping and storage reasons, the Tie Down Sub is carefully packed with great attention and protecting padding against any shipping incident. The sub should be placed in a clean and dry place with minimal chemical and moisture exposure. The sub will not rust and the surface of the sub will be preserved if the sub is correctly stored.
Shipment
Once production and testing are done with the Tie Down Sub, it is specially set for shipping. Shipping methods include the option of expedited shipping if the customer needs it quickly. The shipping package of each item tracks with ease so that the item reaches the customer with ease and promptly. The sub is easy installation and use within perforating gun assemblies the moment it reaches the customer.
