Profile: Flexpert Bellows Private Limited is a manufacturer and exporter of metal bellows, expansion joints & bellow elements. We are an ISO 14001 certified company. Axial expansion joints are the simplest type of expansion joints. They are compact requiring virtually no additional space beyond the length of bellows and weld ends or flanges for installation. They have further advantage of not imposing a change in the direction of flow. Where small thermal movements are involved and where proper anchoring and guiding is possible single axial bellows provide the most economical solution. The most common application for a single axial bellows expansion joints is to absorb axial movements of a straight pipe between main anchors. This axial bellows expansion joint should be placed near one anchor and guides should be utilized to ensure proper alignment and movement control. These single axial bellows are designed to compensate for axial displacements. Our externally pressurized expansion joint takes pressure from the outside of the bellows element rather than on the inside as in a conventional expansion joint. The construction of an externally pressurised expansion joint consists of a heavy outer pipe which contains the pressure and serves as a shroud to protect the bellows and also functions as pipe-guide. The outer pipe contains the full pressure of the system and if bellows failure occurs the medium does not escape radially outwards, thus protecting the personnel working in the vicinity.
