Our customer, PTT Global Chemical Public Company Limited (PTT), a leading global polymer company known for its innovative products and services, operates an LDPE line equipped with a Hyper Compressor from Burckhardt Compression at their Rayong plant in Thailand.
During a recent visit by a Burckhardt Compression field service expert, significant fretting marks were discovered on the distance piece and small end pin. This issue led to unscheduled shutdowns, increased wear, and excessive vibration, resulting in high maintenance costs for PTT. As specialists in parts repair and refurbishment, Burckhardt Compression identified
the root cause and implemented a sustainable solution to enhance reliability. This implementation highlights our dedication to sustainability across all our services and products, emphasizing the longterm environmental and operational benefits.
We were amazed by the level of performance achieved! Burckhardt Compression quickly identified the problem and carried out the repairs with great precision. Given the outstanding results of this project, we plan to involve Burckhardt Compression in many more overhaul projects at other facilities.
