Manway Entrance Installation

JDI originally began working for this client in their Eastern Georgia location, and the projects grew from a few drawings into major work. This manway entrance installation project is one of the projects we win the contract for because of our workmanship history.

We began on the basis of being on a proven vendor listing and are chosen by the manufacturing engineers as the right contractor for the job. Their team struggles to maintain and pump out the wastewater room area underneath their pulp clarifier and press, making this a necessary project.

JDI’s task is to create a manway door that would provide safe, secure access in a confined space, and install safety barriers in front of it to protect maintenance staff when servicing the room in the active work area. This project’s success allows the client the ability to contain the fluids, perform service, and ensure the safety of workers at the plant.

See more details about the project, below.

JDI began the work with pre-fabrication of the steel parts from our in-house fabrication shop. The on-site crew then set, bolted, and welded the metal plates into place around the future door opening.

Afterwards, our contractors cut the opening for the manway installation, then began welding and setting the door frame into place, and then grout in the gaps between concrete and the manway door.

The mechanical crew then installs the Chase CM-1 manway door with a shell size of 43″ outside diameter. This steel manway features an actual clear opening of 36″, with a dish head and shell constructed of 304L stainless steel. The manway is pressure rated and has an EPDM gasket, 1/4″ by 2″ grout ring, and a handwheel operated 1-1/4″ stainless steel-threaded rod.

JDI’s crew then places concrete bollards with steel casings. Furthermore, the crew installs 3/8″ steel plates by welding them to the bollards. The finishing touches of safety yellow are done at the end to create high visibility for the machine operators frequently coming into the area.

• Installation of Pre-Fabricated Steel Package
• Cut opening in concrete wall to provide access
• Welding Manway Door Frame into place
• Grouting around the Manway frame to fill-in gaps
• Stainless Steel Manway Door
• Four concrete bollards and 3/8″ steel plates
• Painting bollards and plates

Our ability to understand this client’s processes, be proactive, and go above and beyond to deliver impresses them. They remark that we keep the plant efficient and safer with the manway entrance.

Before JDI’s completion of this project, the client hadn’t been able to access the clarifier cleanout area properly since the plant’s construction over 50 years ago.

The JDI team members who led the project to the finish line, not just through hard work and expertise, also create establishing relationships with the manufacturer’s managers and employees at the company.
