API 16C High Pressure Long Short Radius Chiksan Swivel Joint For Oilfield Manifold Pipe

Swivel Joint Technical Description:

High-pressure Swivel Joints are commonly used tool for connecting pipelines and sand blasting in oilfield well workover operations. It has the characteristics of variable adjustment direction, fast connection, reasonable structure, small size, light weight, good sealing performance and easy operation. The movable elbow produced by our company is a metal pipeline joint equipped with ball bearings. We can provide various types of movable elbows and repair kits for use under normal temperature, low temperature and sulfur-containing gas conditions.

There are two types of movable elbows: long radius and short radius. The long radius movable elbow has a smooth diameter, which can minimize the resistance when the liquid passes through. The fluid's resistance to erosion and corrosion of the wall thickness at the turning is better than that of the short radius. However, sometimes due to the limitations of on-site installation space or when the pressure is low, short-radius movable elbows are also used. The blanks are formed on CNC machine tools and have uniform wall thickness and long service life. The wall thickness difference between the inner and outer arcs reaches FMC standards, and the appearance quality is extremely smooth; the three-lane design of the movable elbow can more effectively withstand heavy loads and radial loads, making it stable when under pressure and stable in the pipeline when under variable loads. Vibration is smaller.

The high-pressure movable elbow is designed according to API Spec 16C and made of high-quality alloy steel.

The cold working pressure is 42MPa to 105MPa, and there are 2in and 3in high-pressure movable elbows. Commonly used high-pressure movable elbows are type 10 or type 50. The connecting thread of high-pressure movable elbow is usually ACME thread, and the high-pressure movable elbow with tapered pipe thread needs to be specially produced.

Swivel Joint Care And Maintenance:

a) After transporting liquid, rinse thoroughly to reduce corrosion of the movable elbow.

b) Check the movable elbow sealing ring regularly and replace it in time to prevent leakage.

c) Regularly optically inspect the wall thickness of each part of the movable elbow. When the wall thickness is reduced by 20%, it needs to be replaced with a new one.

d) Exposed threads should be coated with anti-rust oil to prevent rust.

e) Change grease regularly.

f) If the surface paint peels off during assembly and use, it should be repainted.
