The Fiberglass Reinforced Plastics Institute (“FRPI”) provides Manufacturer and Equipment Certification to help Owners/End Users and Engineering Firms obtain reliable fiberglass process equipment. Certification provides both a method for manufacturer qualification as well as verification that new installed equipment meets contract reference specifications and standards. Verification includes submittal review, visual inspection, destructive testing and installation assessment.
| Certification is governed by standard practices, specifications and bulletins published in the FRPI Laminate Certification Manual. This Manual is a “Reviewed” document, which was initially accepted by FRPI’s Board of Advisors on November 21, 2005. The Board was staffed at that time by a balanced industry group of seven (7) professional engineers, one (1) of which is a past Chairman of the ASME RTP-1 committee for nine (9) years. The initial document was called the 2004 Edition. Industry and the general public are invited to contact FRPI and comment on the Certification process controlled by the Manual. All comments will be taken into consideration by the Board for future editions of the Manual.

FRPI Certification At Work...
 The FRPI Label.
More than a symbol,
it's peace of mind. | FRPI Helps Advance the Industry!
Now in its eighth year as the industry’s only fiberglass reinforced plastic materials certification non-profit organization, FRPI is leading the way in a new era of quality administration for corrosion resistant process equipment specifiers and buyers. FRPI has made significant progress in advancing material quality, with over $5 million in certified equipment installed and currently going through the certification process. Additional progress has been made through hosting and participating in industry educational seminars, making new publications available that ease control of material quality plus encouraging teamwork among FRP industry leaders that is resulting in quality improvements benefiting specifiers and buyers of FRP process equipment. |
Methuen Construction Supports FRPI Certification |
With experience on three (3) installation projects involving FRPI Certification and dozens of other fiberglass related work under their belt over the past five (5) years, Methuen has learned FRPI is making a difference and improving industry. A number of Project Managers at Methuen, like many contractors, have first hand involvement discovering fiberglass equipment shipped to their sites did not meet spec, had to be dealt with and cost the project more than expected. In a recent case one (1) 12’ diameter 10 PSIG carbon absorber catastrophically failed, resulting in all five (5) being pulled from service and re-built costing the system supplier hundreds of thousands in unplanned repair costs. Although a challenge at first, Methuen supports FRPI Certification and encourages Engineers and Owners to specify this method of Quality Verification for everyone’s benefit. | |
South Windsor WPCF in Connecticut Receives “beefy” Sludge Tank |
 | The new South WIndsor WPCF tank was designed for municipal sludge having a specific gravity of 1.1, with potential sludge surcharge back up loading to 39’ elevation and imposing approximately 6 PSIG pressure on tank. CH Nickerson purchased this FRPI Certified tank from An-Cor DKG, which was manufactured in accordance with Camp Dresser and McKee specifications. A custom engineered hold down system and pressure vessel design following industry standard engineering rules was necessitated by the application. |
AECOM (formerly Metcalf & Eddy) Joint Venture with Hazen and Sawyer on New York City DEP Croton WTP Project |
Thirty-eight (38) tanks were shipped to the New York City DEP Croton Facility. The applications ranged from 15% Sodium Hypochlorite Bulk to UV Cleaning System Waste Storage. Design basis included 2’ depth of buoyancy force, 5 PSIG field hydro test after installation and Level 1 ASME RTP-1 allowable visual defects. FRPI SB01 Level I Engineered Post-Cure and SB03 Preparation for Food Grade Product Contact material treatments were also performed for long term laminate performance. To assure reliability of the flat bottom and top tanks, An-Cor DKG shop hydro tested and proved design in a restraint system built for the project. All tanks met or exceeded contract quality conformance specifications and were FRPI Laminate Certified. Spec development efforts started early in 2004, were refined by January 2006 and installation was completed by Skanska-Tully JV in June 2010. | 12’ Ø Sodium Hypochlorite Tank Under 5.5 PSIG Shop Hydro Test |
Delaware's Justin Tanks Delivers FRPI Certified Tanks to Concord, MA WWTF
The Concord Waste Water Treatment Facility in Concord, MA was the recent recipient of two Alum and two Caustic tanks, both requiring FRPI laminating process and laminate certification. CDM was the designer of this state of the art plant upgrade, which Justin Tanks LLC, Georgetown, DE was the tank manufacturer. With such stringent regulatory requirements, FRPI was chosen as the fiberglass tank quality verification program for this highly acclaimed facility. According to the town of Concord and Waterline Industries, the on-site contractor, the luminary treatment process involving a magnetically enhanced coagulation (CoMag) system will be showcased as the first of its kind. This facility is already gaining significant attention from communities within Massachusetts and as far away as China. Installation of the FRPI vessels three stories below ground level were completed as required.

| Camp Dresser & McKee Specifes FRPI Certified Polymer Tanks in Brockton, MA
Brockton Wastewater Treatment Facility Phase 2 Upgrade is the home of eleven (11) FRPI certified tanks ranging from 1,300 gallon Polymer tanks to 15,000 gallon Ferric Chloride tanks. Walsh Construction installed the vessels in Brockton, MA, which were specified by Camp Dresser & McKee, Inc. All of the vessels required FRPI laminating process and laminate certification and were fabricated and supplied by Justin Tanks LLC, Georgetown, DE. Final installation certification took place in March 2008. |
Town of Mansfield, MA Installs Ventilation System
This FRPI Certified ventilation system installed by Methuen/TMD Construction is designed to handle 2500 fpm hydrogen sulfide and other odorous compounds at a design vacuum of 10” water column. The outdoor portion of the duct has a design differential temperature of 135 degrees F, which equates to a thermal growth of approximately 0.62” from the 30” Ø drop to the 90 degree elbow turning into the farthest Biofilter. Proper support design by the duct manufacturer, An-Cor Industrial Plastics, takes into consideration thermal expansion and contraction of both the horizontal and vertical sections of 30” Ø ductwork and results in stress free operation with expansion joints properly designed and located.

 10’ Ø FRP Sodium Hypochlorite Tank | First FRPI Certified Tanks Installed at Upper Blackstone
Camp, Dresser and McKee specified FRPI Laminating Process and Laminate Certification for three (3) 10’ 15% Sodium Hypochlorite and two (2) 9’ 38% Sodium Bisulfite FRP chemical feed tanks needed by their client, the Upper Blackstone WPAD in Millbury, MA. Walsh Construction handled the purchase of the tanks from An-Cor Industrial Plastics and installation. The CDM lead project engineer commented that this was the first time she didn’t have to worry about the quality conformance for the FRP tank section on one of her projects. Everyone on the project team volunteered how very pleased they were with the success of the installation and FRPI’s Certification process! |

SESD Controls Corrosion with FRPI Certified Ductwork
At the direction of the South Essex Sewerage District Project Manager in Salem, MA, Tighe and Bond Specified FRPI Laminate Certification for over 1,300’ of large diameter round and rectangular ductwork needed to replace a failing stainless steel odor control duct system that was in service for less than ten (10) years. Enterprise Equipment Company, a subcontractor to Methuen Construction, purchased the ductwork, duct system engineering and installation support from An-Cor Industrial Plastics. The Owner, Engineer and Contractors said this is the smoothest installation and best looking ductwork they have seen. |  Rectangular & Round FRP SO2 Ductwork |
