Manufacturing

Niroo Va Tavan Company (NVT) was founded in 1984 and currently is recognized as one of the most reputable private-joint stock companies involved in EPC projects of power section.

Taking into account both wide range of application in various industries, and current impediments to the foreign supply, NVT decided to conduct a comprehensive feasibility study on the local manufacturing of spring supports, and now we are proud to declare our capability to supply them to suit customers requirements in oil, gas, petrochemical, and power industries with superior quality and at keenest costs.

Application

Spring hangers and spring supports are used to balance slight vertical displacements in the pipe system.  These components work on the basis of pre-set helical coil springs which exert a variable supporting load over the range of movement in accordance with their specified spring characteristics. Load variations resulting from this are limited through the stress analysis calculations, depending on the sensitivity of the piping.
