4-1/16 inch ID armored well kill throttle hose
When we deeply explore the armored flexible choke hose with an inner diameter of 4-1/16 inches (101.6 mm) and a design working pressure of up to 10000Psi (about 68.9MPa) under the API 16C standard, we have to first understand its key role and application value in the field of oil and gas exploration, production and transportation. This kind of highly specialized pipeline system not only represents the top achievements of materials science and engineering technology, but also is an indispensable part of modern energy development. This article was written by LETONE Marketing Department on August 15, 2024, mainly explaining some design features and applications of API16C
1. Overview of API 16C Standard
API 16C standard, full name "Choke and Kill Systems for Drilling Wells", is an internationally recognized industry standard developed by the American Petroleum Institute (American Petroleum Institute), which is specifically used to guide the design and manufacture of BOP systems in drilling operations, including choke manifolds and well kill manifolds. The standard specifies in detail the material selection, design pressure, temperature range, performance test and installation requirements of choke tubes, well-killing tubes and their accessories to ensure safe and reliable operation under extreme working conditions.
2. The significance of 4-1/16-inch inner diameter and 10000Psi working pressure
Inner diameter size: The selection of 4-1/16-inch inner diameter is based on a comprehensive consideration of fluid flow requirements, pipeline resistance and equipment compatibility. This size not only ensures sufficient fluid flow capacity, but also takes into account the compactness and economy of the equipment. In deep-sea drilling or high-pressure oil and gas well operations, precise control of fluid flow is crucial, and the appropriate inner diameter of the pipeline is the basis for achieving this goal.
Working pressure: The working pressure requirement of 10000Psi reflects the working ability of the choke tube under extreme conditions. In oil and gas exploration and development, the formation pressure may be far beyond the conventional level, especially in deep, ultra-deep or high temperature and high pressure environments. Therefore, designing and manufacturing choke tubes that can withstand such high pressures is the key to ensuring safe and efficient drilling operations.
3. Technical features of armored flexible throttle tube
Armored design: The core of armored flexible throttle tube lies in its unique external protective layer, which is usually made of high-strength alloy steel or composite materials. It can effectively resist external impact, corrosion and the influence of harsh environment, and extend the service life of the pipeline. At the same time, the armor layer also provides additional structural support, which enhances the pressure bearing capacity and stability of the pipeline.
Flexible structure: Unlike traditional rigid pipelines, armored flexible throttle tubes have certain bending and expansion. The flexible design allows the throttle tube to bend flexibly in complex and changeable wellbore trajectories, reducing the use of connectors and the risk of leakage, while improving the reliability and maintenance convenience of the overall system.
4. Deep-sea oil and gas exploration
In the field of deep-sea oil and gas exploration, API 16C armored flexible throttle hose are particularly widely used. The deep-sea environment not only has huge water pressure, but also has a high content of corrosive substances such as salt and sulfide in seawater, which puts extremely high demands on the performance of throttle tubes. By adopting advanced material science and manufacturing technology, these throttle tubes can work stably at a depth of thousands of meters on the seabed, providing strong guarantees for the safe exploitation of deep-sea oil and gas fields.
In view of the harsh working environment, API 16C armored flexible throttle tube is very particular about material selection. High-strength alloy steel or special corrosion-resistant alloy is usually used as the main material to cope with the challenges of high pressure, high temperature and corrosive media. In addition, the internal flow channel may also be coated with a special anti-corrosion coating to further improve the corrosion resistance of the throttle tube and ensure long-term stable operation.
