Description
API Wellhead Chiksan High Pressure Fig1502 Swivel Elbow Joint
The high-pressure Swivel elbow is designed according to API Spec 16C and made of high-quality alloy steel. Chiksan Elbow Swivel Joints adopts a three channel design with uniform wall thickness. The long radius high-pressure adapter elbow can ensure that the same radius of sphere can freely pass through the inside of the elbow. The high-pressure movable elbow is connected by wing nuts and has the characteristics of fast tightening, unloading, and pressure sealing. The high-pressure Long Radius Swivel Joint elbow can be used in high-pressure discharge pipelines, input pipelines,temporary liquid flow pipelines,well testing pipelines, and other acidic working environments for conveying liquid flow under high-pressure conditions.Cold working pressure ranges from 6100psi to 15000Psi,with high-pressure movable elbows of 2in and 3in.The commonly used high-pressure Wellhead elbows are Type 10 or 50 Type. The connection thread of high-pressure Union Chiksan Joint Swivel Joint is usually ACME thread, while high-pressure API 16c FMC elbows with tapered pipe threads require specialized production.
2、 Structural features:
The Hammer Union elbow has the characteristics of flexibility,impact resistance,vibration resistance and large flow rate.The Swivel Joint elbow is connected by wing nuts, which have the characteristics of fast tightening, unloading, and pressure sealing, making it convenient for transportation and storage.
3、 Instructions for use:
1. Do not use Swivel Joint elbows on continuously rotating mechanical devices.
2. Reasonably select corresponding specifications based on actual work pressure and structure.
3. Flexible elbows should not be used in acidic gas environments (including CO2 and H2S) (unless specifically ordered for acid resistant gas flexible elbows).
4. The Swivel Joint elbow cannot withstand axial loads during operation.
5. No additional load can be applied to the movable elbow.
6. When tightening the wing nut, do not use hammering force that deforms or damages the wing nut. The operator must wear protective goggles,
To prevent metal fragments from injuring the eyes.
4、 Maintenance and upkeep:
a) After conveying the liquid, it is necessary to thoroughly rinse to reduce corrosion on the Swivel elbow.
b) Regularly inspect the sealing ring of the movable elbow and replace it in a timely manner to prevent leakage.
c) Regularly inspect the optical thickness of each part of the Swivel elbow, and replace it with a new one if the wall thickness is reduced by 20%.
d) Exposed threads should be coated with rust proof oil to prevent rusting.
e) Regularly replace lubricating grease.
f) If the surface paint peels off during assembly and use, it should be repainted.
