A complete product portfolio of more than 16,000 standardized components covers all support situations, operational loads, temperatures and travel ranges normally experienced in piping systems in industrial plant construction. LISEGA’s modular system provides the corresponding basis. All components have a connection compatible with their load groups.
How do you release the tension to bring the rams back down to reconnect the pipe? We had a base plate break off and need to bring the rams back down to reconnect the piping on a running unit that we cant bring down.
Please contact us at info@us.lisega.com. We will connect you with an expert who can get more information about your specific situation and walk you through the process to safely perform the necessary adjustments.
Snubbers do not come locked. Snubbers come packaged very carefully to prevent any damage during transport. They can be installed very easily and are ready to function. If they happen to be locked due to a sudden "event" such as shifting during transport, they will unlock and be functional without any outside intervention. Please feel free to email us at info@us.lisega.com if you have any questions or would like additional information regarding snubbers. Thanks!
Thank you, they truly are a valuable tool in the world of pipe supports. You may be interested in some of the other videos we have posted, particularly about constant hangers. Feel free to explore our channel and our website. If you have any questions, feel free to contact your nearest LISEGA representative.
How can you adjust a load on variable spring hanger at site, when spring has plus or minus 5 % load tolerance on spring rate , it can be calibrated only on test rig for accurate new load, site adjustment not Recommended.
When we set the spring at the factory we use the ACTUAL force the spring is exerting on the test bench. We do not use, or even have, a load scale on the variable spring itself. By computing the desired new force using the mathematical process explained in this video (which is much more precise than using a load scale) the new force will be accurate enough for most situations. If the new desired force is REQUIRED to be exact then we recommend sending the spring to our factory and resetting the load on our test bench.
Understood this video.. My question, how to know when to adjust the load using those two bolt and why not adjusting using the turnbuckle. Thanks in advance
Basically the load adjustment bolts are intended for high variation in load change with minimal deviation in load point elevation. When minor correction is needed with respect to altering the load point elevation along with slight deviations in load is not worrisome, it should be tried with turn buckle.
The red and white marks on a constant force spring show the calculated hot & cold POSITION of the spring. The marks do not indicate the load the spring is applying. The LOAD the spring is applying on the pipe remains the same throughout the entire range of travel (this is much different than on a variable spring). Changing the dimension using a turnbuckle will only change the position of the pipe, but not the load the spring is applying. Changing the position of the pipe will shift the pipe load to nearby springs. The only way to change the load that this particular spring is applying is by using the two load adjustment bolts.
