Test method for long-term hydrostatic pressure of glass fiber reinforced thermosetting resin pipe fittings ICS 83.120 Q23 National Standards of People's Republic of China Glass fiber reinforced thermosetting resin tube and Long - term hydrostatic test method for pipe fittings 2016-02-24 released 2017-01-01 Implementation General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China China National Standardization Management Committee released ForewordThis standard is drafted in accordance with the rules given in GB/T 1.1-2009. This standard is proposed by the China Building Materials Federation. This standard is under the jurisdiction of the National Technical Committee for Fiber Reinforced Plastics (SAC/TC39). This standard is responsible for drafting units. Beijing FRP Research and Design Institute Co., Ltd., Wuhan University of Technology, Tongji University, Zhejiang Oriental Hao Bo tube Co., Ltd., Hebei can Knight Fiberglass Co., Ltd. The main drafters of this standard. Zhang Lichen, Yang Jiping, Chen Jianzhong, Zhou Shigang, Su Yuehui, Gao Donghe, Li Tong. Glass fiber reinforced thermosetting resin tube and Long - term hydrostatic test method for pipe fittings1 ScopeThis standard specifies the term and definition of glass fiber reinforced thermosetting resin pipes and fittings for long-term hydrostatic test, test principle, specimen, Test conditions and test equipment, test procedures, hydrostatic design basis or pressure design basis to determine and re-identification, test reports. This standard applies to thin-walled glass fiber reinforced thermosetting resin pipes and fittings. Note. The thin-walled tube means that the ratio of outer diameter to wall thickness is greater than or equal to 10. 1, which limits the internal pressure of the pipe. According to the circumferential stress equation, Is roughly 20% of the hydrostatic design basis and is independent of diameter.2 normative reference documentsThe following documents are indispensable for the application of this document. For dated references, only the dated edition applies to this article Pieces. For undated references, the latest edition (including all modifications) applies to this document. Test method for short - term hydraulic pressure failure of GB/T 5351 fiber reinforced thermosetting plastic tubing3 terms and definitionsThe following terms and definitions apply to this document. 3.1 Free end seal free-endclosure A seal device which is fixed at the end of the specimen so that the specimen can produce axial stress in addition to the circumferential stress, structure. 3.2 Constrained end closed A seal or structure fixed to the end of the specimen, which relies on a rod or external structure that passes through the interior of the specimen, From the axial thrust, so as to limit the stress in the sample ring. 3.3 Failure failure The test liquid flows in any form through the test tube, such as wall fracture, partial leakage, greater than double the diameter of the seal The distance outside the liquid exudation. Note. For this standard, the sample has not yet failed, according to 6.6 and 9.2 specific conditions, can also be used as a failure. 3.4 Toroidal stress hoopstress The tensile stress in the circumferential direction caused by the internal pressure in the tube wall of the tubular product. The circumferential stress was measured by a straight hollow cylinder sample (1) Calculation. S = p D - tr ()/2tr () (1) Where. S --- toroidal stress in MPa (MPa); ......Tips & Frequently Asked Questions:Question 1: How long will the true-PDF of GB/T 32491-2016_English be delivered?Answer: Upon your order, we will start to translate GB/T 32491-2016_English as soon as possible, and keep you informed of the progress.
