Hard Ground Pre-Boring "Low Head MLT Method"

Hard Ground Pre-Boring "Low Head MLT Method"

Corresponds to areas such as under bridges, substations, and power plants! Low headroom construction method using a pile driver for hard ground with a height of 4m!

The "Low-Head MLT Method" is a low-head version of the "MLT Method," which efficiently excavates hard ground by compressing the excavated soil against the borehole wall using a special screw consisting of a compression wing and a mixing wing. *Are you facing challenges in locations where the ground is high and there are restrictions above? - Under bridges - Inside substations and power plants - Inside factory buildings By improving the conventional hard ground pre-boring method (MLT method) drilling machine, we have developed a pile driver for hard ground with a height of 4 meters without reducing the excavation power. This machine is designed to handle construction in sites with headroom restrictions and narrow spaces. 【Features】 ■ 4-meter high pile driver for hard ground ■ Suitable for construction in sites with headroom restrictions and narrow spaces ■ Compresses excavated soil against the borehole wall using a special screw consisting of a compression wing and a mixing wing ■ Vibration-free and low noise *For more details, please refer to the PDF document or feel free to contact us.

Hot spring and hot water pipe GNGAR: Insulation properties & maximum usage temperature 95℃!

Hot spring and hot water pipe GNGAR: Insulation properties & maximum usage temperature 95℃!

Solving issues such as scale buildup, corrosion, and heat loss due to water quality! Numerous achievements in hot spring piping and heat supply piping!

GNGAR is an insulated pipe structure primarily used for hot springs and hot water. Nominal diameter: 25–250 Maximum operating temperature: 95℃ 【Features】 ○ The conduit is made of cross-linked polyethylene, which has characteristics such as heat resistance and chemical stability. ○ The use of EF sockets made of cross-linked polyethylene eliminates concerns about corrosion, similar to traditional metal fittings. ○ It is a long pipe that has undergone consistent processing for insulation, installation, and corrosion protection in the factory. ○ Pipes with a nominal diameter of 100 or less can be delivered to the site as long pipes (tab-wound). ○ The delivery of long pipes allows for labor-saving in construction and shortening of construction periods, which can reduce construction costs. ○ The long pipes are flexible and can be extended while bending. ○ They are ideal for exposed piping in mountainous areas and for soft ground such as marshes and reclaimed land, and they also excel in seismic resistance. ○ The outer layer is coated with low-density polyethylene containing carbon black, providing excellent weather resistance and corrosion resistance.

Water Supply and Drainage (Insulated) Pipe GNGWDA - Outstanding Freeze Prevention Performance!

Water Supply and Drainage (Insulated) Pipe GNGWDA - Outstanding Freeze Prevention Performance!

Lightweight, long-length, high strength, and excellent insulation performance! It is a high-performance freeze prevention pipe!

GNGWDA is increasingly being adopted for bridge attachments and suspended piping due to its unique characteristics of lightweight, flexibility, and earthquake resistance that are not found in other types of pipes. Nominal diameter: W40 to W100 (The conduit dimensions conform to ISO standards.) 【Features】 ○ The composite pipe structure of polyethylene and aramid fibers provides high internal pressure strength, and the corrugated steel pipe protects against external pressure. ○ The rigid polyurethane insulation layer prevents freezing of fluids inside the conduit. ○ Pipes with a nominal diameter of W100 or less can be delivered to the site as long pipes (tab-wound). ○ The use of long pipes can reduce labor and shorten construction time, leading to cost savings. ○ The long pipes are flexible and can be extended while bending. ○ They are ideal for soft ground such as marshy areas and reclaimed land, and they also excel in earthquake resistance. ○ The outermost layer is coated with low-density polyethylene containing carbon black, which offers excellent weather resistance and corrosion resistance, making it suitable for exposed pipes. ○ EF fusion and automatic butt fusion create a reliable pipeline with a unified structure. ○ It has sufficient weather resistance and internal and external pressure strength for use as bridge attachment pipes.
