Swivel joint 50-300
Swivel joint PST renders possible to make rigid pipe construction flexible. If using one flex joint equipment moves on 360 degrees in one plane. If using three flex joint equipment moves in three planes. PST is full bore flex joint is provided minimal drop of pressure. Joint is for wide production range.
- Ball and cone bearing combination provides high load capability of joint.
- Engineers can replace flex joint grummet without bearing breaking-off.
- Double sealing protects ball bearing cell from leakage if general grummet damage.
- Control sealing between flex joint grummets and bearings.
- Dust-proofing ejects solid particles entry.
- Bearing is crowded by conducting long-life performance lubrication, so it is not necessary in constant maintenance.
- There is galvanic coupling wave guide according to electrosafety requirements.
- Bearing construction provides it inner and external sealability.
