ASME STANDARDS TECHNOLOGY, LLC RFP-ASMEST Request For Proposal: Fiberglass Reinforced Plastic (FRP) Peel Testing Solicitation Date: September 18, 2014 Proposal Due Date: October 17, Summary
ASME STANDARDS TECHNOLOGY, LLC RFP-ASMEST Request For Proposal: Fiberglass Reinforced Plastic (FRP) Peel Testing Solicitation Date: September 18, 2014 Proposal Due Date: October 17, Summary ASME Standards Technology, LLC (ASME ST-LLC) is soliciting a proposal to conduct fiberglass reinforced plastic (FRP) peel testing. This project results from ASME Pressure Technology Codes and Standards (PTCS) Standards Committee requests to identify, prioritize, and address technology gaps in PTCS Codes, Standards, and Guidelines, and intends to establish and maintain the technical relevance of ASME codes and standards products. All open RFPs are posted on 2. Background When designing FRP vessels, one of the most significant differences from metal vessels is designing for peel conditions. Peel is when the load is perpendicular to the plane of the bonding area similar to peeling an adhesive bandage. It takes much less load to peel an adhesive bandage off than it would to pull it parallel to the plane of the bonding area. Metals do not have a significantly weaker peel strength like FRP does. The best design is to avoid configurations that create peeling action, but there are many reasons why peeling cannot be always avoided, so a peel design method is needed to provide a conservative design. Presently, the only industry-available peel design information is the generally accepted 50 pounds per inch (lb/in.) that is documented in ASME Reinforced Thermoset Plastic RTP-1 standard. Peel strength would be affected by the attachment thickness and material properties, and experience shows that attachments can resist higher peel loads than the 50 lb/in. standard, so the design method should take these factors into consideration. It is easy for an FRP designer to under-design for peel conditions, and this is especially easy for designers not familiar with FRP. It is believed that are many engineering companies and metal designers that are designing FRP without being aware of this issue. Because the ASME RTP-1, Section X standard and the Non-Metallic Piping 9/17/2014 Page 1 of 13 ASME ST-LLC RFP 15-01, FRP Peel Testing standard were written to help ensure the safe design of FRP vessels, peel is one of the most important issues that must be addressed and documented in these standards. Poor peel design has led to the failure of lift lugs, hold down lugs, nozzle attachments, support clips, baffles, and many other attachments. In addition to the immediate consequences of such failures, the industry would also have to deal with the loss of confidence in FRP equipment compared to other materials. This can negatively affect all factions of the industry including material suppliers, engineering companies, FRP fabricators, inspectors, and end-users. 3. Scope of Work a. Summary: Following summarizes the Consultant s scope of work. The work would consist of two phases. Phase I would be focused on determining which of the below parameters have a significant variation. Phase II would be focused on testing those parameters having a significant variation to evaluate the thickness variation for the nozzle load cases. FRP samples would be purchased for testing from fabricators who are ASME RTP-1 or Section X, Class 2 stamp holders. The testing laboratory would make two testing jigs and cut and test each sample. Some samples could be cut into five (5) coupons to create a larger sample size, and some would be tested once because it wouldn t be practical to cut them into smaller pieces. A combination of the following parameters would be evaluated pursuant to the Conceptual Peel Strength Chart see Annex A: i. Three (3) different weld thicknesses. ii. iii. iv. Three (3) different resin elongation ranges. Two (2) different resin manufacturers. Two (2) different glass manufacturers. v. Three (3) different fabricators. vi. vii. viii. Three (3) different number of mat layers before the first woven roving. Two (2) different glass types. Eleven (11) different peel load cases. Refer to the attached sample drawings PEEL-B1 through PEEL-B6. b. Phase I Criteria: In performing Phase I of the scope of work, Consultant shall adhere to the following criteria: i. All samples will be the Perpendicular Double T Weld samples per drawing PEEL- B1 with inch thick welds. ii. One (1) fabricator makes three (3) samples using three (3) different elongation ranges from one (1) resin manufacturer. 9/17/2014 Page 2 of 13 ASME ST-LLC RFP 15-01, FRP Peel Testing iii. One (1) fabricator makes two (2) samples using resins with the 1.2% to 2.5% elongation range from two (2) different resin manufacturers. iv. One (1) fabricator makes two (2) samples using 1.5-ounce chopped strand mat and 24-ounce woven roving, each of which are from two (2) different glass manufacturers (1 domestic, 1 foreign). v. Three (3) different fabricators each make one (1) sample using the same resin. vi. One (1) fabricator makes three (3) samples using three (3) different quantities of mat layers before the first woven roving (1 mat, 2 mats, 3 mats). vii. One (1) fabricator makes two (2) samples using two (2) different types of glass (Eglass, ECR-glass). c. Phase II Criteria: In performing Phase II the scope of work, Consultant shall adhere to the following criteria: i. Samples and testing are to evaluate only thickness variation for the nozzle load cases. ii. Samples will be all those specified on drawings PEEL-B4, PEEL-B5, and PEEL- B6. d. Deliverables The key project deliverables are the following: i. Interim Report on the results of testing conducted in Phase I. ii. iii. Draft Report analyzing the testing conducted in Phase II. Final Report incorporating comments from ASME staff and volunteers as applicable. All written deliverables shall be provided as a Microsoft Word file that is formatted in accordance with the ASME Style Guide. One (1) peer review cycle of the Draft Report is anticipated, and modifications required to the Draft Report as a result of the review cycle are the responsibility of the Consultant awarded the contract. e. Schedule The Consultant shall submit a schedule with its proposal that provides major milestones, deliverables, and a reporting schedule. The final deliverable should be completed no later than May 31, f. Status Reporting The Consultant shall provide a brief status report on a monthly basis, via , to the ASME ST-LLC project manager. Progress reports shall be presented at ASME BPV VIII committee meetings, as requested. 9/17/2014 Page 3 of 13 ASME ST-LLC RFP 15-01, FRP Peel Testing 4.
