Approved Factory by the Japanese Sewage Association Steel segments are fabricated from standard hot-rolled mild steel. They are designed to offer higher strength, ease of transportation, better capability for in-situ modification, and higher tolerance. Generally, they are designed for cross passages and small-radius tunnel curves, such as those in underground cable tunnels and gas tunnels.
Unicrane welders have successfully passed the JIS welding test, ensuring that our welding techniques meet the highest quality standards. With our production arrangements and management experience, our capacity for steel segment fabrication can reach up to 30,000 rings per year.
Unicrane is also an approved factory by the Japanese Sewage Association, allowing us to sell steel segments back to Japan for sewage purposes. There are only two factories in Asia approved by the Japanese Sewage Association, and Unicrane is one of them.          Unicrane Machinery has been cooperating with Nippon Hum Concrete to apply for approval from the Japanese Sewage Association, and it was granted approval in February 2013. The scope of fabrication specifications ranges from an outer diameter of 1,800 mm to 8,300 mm.
