共栄建機 Company Profile

We support our customers with our service products and help enrich society.

Kyoei Kenki Co., Ltd. was established with the main business of repairing and maintaining engine welding machines. Subsequently, we began pressure and leak tests for gas piping, as well as pig cleaning work, and have since fully launched our rental business, leading us to the present day. Our staff, backed by experience and technology, is here to assist you.
