CUSTOMER REQUIREMENT

Reliable absorption of thermal expansions and mechanical movements in hot gas outlet pipes is of great importance for uninterrupted operation of gas lines. In line with this need, a durable and reliable expansion joint design capable of movement in all directions was requested. According to customer demands, a special rectangular lens metal expansion joint with 1500x1500 mm flange dimensions was developed.

SOLUTION – High Performance and Durable Expansion Joint Design

This rectangular lens metal expansion joint was carefully designed and manufactured to have a spring rate of 17,500 N/cm (±2%). Thus, only 105,000 N force was made sufficient for 60 mm axial movement. This superior design of the expansion joint ensures effective management of expansion and movements in hot gas lines.

AISI 316L (1.4404) grade stainless steel material was preferred to provide superior resistance against corrosive effects of hot gas. This material selection offers long-lasting protection against both high temperatures and chemical effects. Thanks to its rectangular design and omnidirectional movement capability, this expansion joint smoothly absorbs all thermal and mechanical movements in the gas line.

This lens metal expansion joint ensures reliable operation of gas lines even under challenging operating conditions in the iron-steel sector, guaranteeing operational continuity and customer satisfaction.
