Technology / product information

Penstock (Piping) and Trash Screens are critical structural components that support the efficiency and stable operation of hydropower plants. The penstock is a pipe that withstands pressure from water head differences and delivers water to the turbines, while the trash rack is a device that removes debris and foreign objects from the water flow, significantly contributing to equipment protection and reducing maintenance costs. The manufacturing of these products utilizes advanced can welding technology, particularly excelling in handling thick plates and large-scale products.
LILAMA10 employs 398 skilled technicians who, based on their extensive experience and advanced technical expertise in welding processes, deliver reliable quality. Additionally, through calculations and simulations from the design stage, we propose optimal welding methods to provide products with superior durability.
