Your business partner — JH Engineering

JH Engineering succeeded in localising hot tapping and line stopping equipment, and today supplies that equipment and its consumables throughout Korea. We have grown on the strength of product quality, trust and fast after-sales service.

Built on that engineering capability, we also work as a specialist hot tapping contractor, relocating water, city gas, district heating and industrial plant piping without any interruption to supply.

To respond flexibly to a fast-changing market and to stay a step ahead of it, we draw on the know-how accumulated over the years to keep identifying new items and bringing their production in-house.

We promise to remain the first partner our customers trust, and to write the next chapter of safety equipment and hot tapping together with them.

Thank you.
