Our D1133 swivel joint is a variant of the basic D0002. It is the ideal swivel joint for nearly all applications in the chemical industry. It has a minimal structural length, minimal external diameter and minimal weight.
In the D1133 swivel joint the ball track is encapsulated by two O-rings, neither dirt from the outside nor product from within (in case of leakage) can reach the ball track. Should the main seal fail, leakage is indicated through the leak detection ports.
The internal flange makes it possible to change the seal without removing the swivel joint from the pipeline. The D1133 swivel joint can be relubricated via grease nipples if it is not provided with life time grease. If required, the balls can be removed and replaced by first removing the ball track plug.
The ball track of the steel version is hardened and polished. This gives the swivel joint a high degree of running precision and long service life, even under extreme loads. The sealing surfaces are plated with stainless steel and precision-finished to prevent corrosion, ensuring that the seal that slides along these sealing surfaces is not damaged and will seal perfectly.
The D1133 swivel joint in stainless steel is used for applications where aggressive media are encountered internally and externally, and therefore the internal parts as well as the external parts are made of stainless steel. Depending on the expected load the ball track can be hardened or unhardened. If hardened, a special alloy is welded into the raw material before mechanical processing.
