Quality and Safety

Ensuring quality of product

EGC Critical Components addresses quality at every step in the process – concept to completion. Our investment in state-of-the-art manufacturing technology, from robotics to cleanrooms, ensures the maximum level of precision manufacturing.

Customer requirements are met through detailed contract review, well defined and repeatable processes and statistically based inspection plans in accordance with API Specification Q1 Ninth Edition. API Q1 certification gives EGC an additional competitive advantage within the Oil and Gas market for licensing to API product specifications. We are also maintaining our ISO 9001:2015 certification.

Quality also involves product delivery. EGC excels at developing solutions and delivering them within agreed lead times. To meet client schedules without interruption, we track performance at each stage in the manufacturing process through delivery of the final product.
