Before you choose a BOP well-control hose, it is important to know what medium it contains. It should be able to tell you the temperature range, minimum bend radius, as well as the pressure range. These details will assist you in making the best decision. It will also help you decide if the hose is right for your application.
What temperature range does the BOP well-control hose operate in?
BOP well control Hose is certified to API 16D. It is made up of multiple layers of textile fabric, steel cable, and a rubber cover. This material is designed to withstand abrasion and cutting. It also offers excellent flexibility. It is resistant to oil, abrasion and kinking. Its design meets the requirements of the EUB Directive 36 and Lloyd's Register. It is available in common lengths of 3/ 8" to 2/ ID.
The temperature range of a BOP well control hose should be within a temperature range of -50degF to 100degF. Temperature testing is part of the API Standard 53 maintenance program. For BOP well control hoses, the accumulator must be calibrated according to the manufacturer's specifications and the operating temperature. The manufacturer must file the calibration results with the well-specific data package.
According to API Standard 53, a BOP installation must have a minimum working pressure equal to the anticipated surface pressure. The Minimum Pressure Rating of the BOP should be determined by the MASP of each well. This should help you choose the proper BOP for your well.
API Standard 53 requires that choke control stations must have at least two remotely operated chokes. It should also include a choke control panel with at least two independent control valves. Many choke manifolds for 10K have both a manual and hydraulic choke. However, adding a second hydraulic choke would require additional plumbing and space. API Standard 53 doesn't take into account drilling risks.
What is the minimum radius of bend for BOP well control pipes?
When choosing a BOP well-control hose, the minimum radius of bend is an important factor to consider. This measurement indicates how far the hose must bend in order to make a 90 degree bend. Too sharp an angle can stress the hose's reinforcements and reduce its service life. Some hose types are prone to kink at extreme bends. "Helix" hose is used for those more severe bends.
Minimum bend radii are dependent on the diameter of the hose and its operating pressure. For example, a hose with a diameter of -8 inches will need a minimum bend radius of two and a half inches, while a hose with a maximum operating pressure of 2000 psi will require a minimum bend radius of seven inches.
The minimum bend radius for BOP well control hoses is determined by the smallest diameter of the bend between the hose and the well control stack. The connection must be secure when the hoses are connected together in the water column. This will prevent kinking or crimping.
BOP well control pipes have a minimum bend radius determined by the diameter and pressure of the hose. Typical diameters range from two-half inches to four inches, and the length varies from fifty to 110 feet. Proprietary manufacturers of subsea hose bundles aim to provide low-volumetric expansion to ensure the lowest API closing time.
What is the pressure range for the BOP well-control hose?
You should consider the pressure range it can handle when choosing the right hose to fit your BOP. It should be able to work in a pressure range of 1300 to 5000 psi. This means that the hoses cannot be connected in bundles.
When selecting the right hose, you should also consider the operating temperature of the well. The accumulator's operating temperature must be lower than the BOP's working pressure. This can be calculated by using the manufacturer's surface pressure and the temperature at the BOP. These results should be documented and kept on file in your well-specific information package.
The BOP hose should be installed and tested to the proper pressure range before it is used in the drilling process. It should have two sets of pipe rams, one of which must be designed to seal around a larger drill string, and another set that is designed for smaller pipes. It is also important to ensure that the BOP is able to handle the pressure of the bottom hole tools.
Be sure to purchase genuine BOP parts when buying a hose. API Standard 53 stipulates that a ram BOP installed must have a pressure equal to the maximum surface tension of the well. Then, you need to determine the BOP Stack Classification and Pressure Rating for your BOP equipment.
