AcuFlow Services works with Historical Plaster Conservation Services on unique project

Internal Inspection and Restoration of 16 Life Size Statues at Bronx Community College, New York City

AcuFlow Services was pleased to be selected to participate in this very unique project.

This project was located at the Gould memorial library, designed by Sanford White of McKim Mead and White, built in 1897 at the present site of Bronx Community College, New York.

During planning for an extensive restoration of the coffered ceiling in the main rotunda it was discovered several statues, located atop a balustrade, on a mezzanine had come loose from the main base they were mounted on. The bases consisted of a two tiered platform and the top tier had become separated from the bottom.

This posed a number of problems, first and foremost was the safety issue, these were standing approximately 50 feet above the main floor. Second, these statues formed an integral part of the original design and it was hoped a method of consolidating the separated joints with minimal intervention could be found.

A 15mm or 3/4" opening was drilled into the base of the statues allowing a 8.4mm or 3/8" flexible fiber scope, fitted with a small hose and spray nozzle, to be inserted into base. The joint of the two tiers could be clearly viewed and through the use of the spray nozzle, attached to a pump, the internal joint was spray injected with a liquid bonding agent.

The flexible fiber scope combined with the articulation capabilities allowed the entire joint to be treated from one opening. The joint was first sprayed with a neutralizer followed by one application of 50% bonding agent/drying agent followed by 100% bonding agent.

The results were a complete strong adhesion of the two base sections with minimal restoration required to repair the 3/4" opening.

 

 

 



 

AcuFlow designs system to enhance Pulp and Paper 

AcuFlow Services has developed a new camera system specifically designed for inspecting Felt rolls. This new process allows Felt rolls to be inspected quickly and efficiently during scheduled shutdown while the felt is removed and the roll is free to be rotated. The purpose is to locate any small cracks, corrosion or anomalies on the surface of the roll before they become a major problem resulting in injury or lost production time.

 

A custom made guide bar is positioned across the width of the roll on the paper machine, a stabilizing bar is attached at either end to tighten to the machine framework. This allows us to fine tune the positioning and insure it is level to the roll.

Prior to each roll inspection the individual roll number or (part designation) is recorded onto the videotape followed by the inspection itself. A miniature camera with integral lighting is inserted into the guide bar and is then moved laterally across the entire roll length. As every roll location is different within the context of the machine some rolls can be done in 2 passes i.e.: 1 half roll, rotate the roll and draw the camera back while recording the 2nd pass. Depending on the individual case some rolls require 4 passes, meaning the roll is inspected as 4 quarters.

 

This is a two person operation and an average roll can be fully inspected and recorded onto Videotape in under 15 minutes. We are extremely careful during deployment and removal to not come into contact with the roll face.

 

Please feel free to send an email or call to find out how we can save you time and unexpected downtime on your next shutdown.

 

And remember, in Pulp and Paper, we are your source for internal inspections of Pulp Presses, Taper Headers, Head Box Tubes, Heat Exchangers, Recovery Boilers, Evaporator Tubes, Boiler tubes, Dryer Cans, Tanks, Silos, Gear Housings, Process Lines, as well as Pressure Vessels.

 

 


 

FOR IMMEDIATE RELEASE
AcuFlow Diagnostics develops inspection program for Water Treatment Plants Filter Cell Clay Block Under Drain Inspection and Cleaning
Project:
Client at a large municipal water treatment plant has a concern about filter media, in this case anthracite, infiltrating the dual chamber, upper and lower, clay block filter beds and getting into the clear well.
Solution:
Each filter cell has 48 laterals, each of 12 filter cells were cored, using a water cooled diamond tip cutter to provide the smoothest cut, at two laterals within the cell. It was felt this would give an idea of general conditions in each cell as a preliminary test.
Each lateral was cored into the upper chamber using a 3 inch bit and the lower chamber using a 21/2" bit, this is to accommodate the installation of a dual locking plug after inspection.
A .9" 17mm push camera was used to inspect the upper then lower lateral channels for their entire length. There was media present in all laterals in varying degrees as was anticipated. It was also discovered that the grout used to join the clay tile was eroding and infiltrating the system as well.
The original plan called for a cleaning of the laterals by use of a conventional water jetter after inspection if required, using the pressurized water to draw all material present back to the opening and using a wet vac to pull it out. We soon realized the water jetter was serving to further erode the grout so this was replaced by attaching a vacuum head to camera so the cleaning process could be viewed to ensure a complete cleaning.
