A manhole cover with a wide range of lineup on the top of the pressure tank.
The outward-opening type manhole cover type HLSD-2 is used for pressurized tanks or containers that require a hatch for access to the inside of the tank.
Used for pressurized tanks or containers that require a hatch for access to the tank.
The access tank cover round cover "HLSD-2 type" is used for pressurized tanks and containers that require a hatch for access inside the tank. The HLSD-2 is approved for use with pressure vessels compliant with PED97/23/EC. The HLSD-2 maintains a complete seal when closed, thanks to load spring bolts and seals within the cover. The cover is mounted to the frame with a highly rigid hinge, ensuring high accuracy in the closed position, and when opened, it remains stationary at an angle exceeding 20 to 30° from the vertical position.

Small lots starting from just one piece are OK! No molds required, allowing for free shapes and cost reduction. The bending process of the craft former requires no cutting oil and generates minimal chips, making it energy-efficient and material-saving.
We manufacture various shapes of covers and circular covers using the stamping sheet metal technology developed from the production of Shinkansen train car bodies. 【Overview】 Processing method: Bending processing using a craft former Size: 1.2t × 20 × 50 φ150 *Please consult us Material: Stainless steel, aluminum, iron, etc. Lot size: 1 to 100 *Please consult us <Case Information> We received a request for the production of a circular cover with a minimum radius of φ120, which was difficult to achieve with conventional machining. By utilizing stamping sheet metal technology, we were able to achieve high-precision curved surface processing without the need for dedicated molds, meeting our customer's requirements. We are continuously conducting prototypes, so please feel free to contact us. *For more details, please download the PDF or feel free to contact us.
