3. Ring tensile test 3.1 The sections of pipe measuring about 15 mm in length shall have plane and smoothed ends and shall be at right angle to the pipe axis. To perform this test, the pipe sections are stretched in a tensile testing machine until fracture occurs using two pins with a diameter equal to at least three times the wall thickness of the pipe, see Figure 2.10. In the case of welded pipes, the specimen shall be placed in the tensile testing device in such a way that the welded seam lies at 90° to the direction of the tensile load. The rate of the pins may not exceed 5 mm/s. 4. Drift expanding test 4.1 To perform this test, a tapered drift is forced into the specimen until the outside diameter has increased to the prescribed value C for the product in question, see Figure 2.11. The length of the specimen and the taper angle β of the drift shall be as shown in the following Table. The intrusion rate of the taper may not exceed 50 mm/s. 5. Flanging test 5.1 To perform this test, a sample of pipe with a length L = 1,5 D is worked into a flange in the device shown in Figure 2.12 until the outer diameter C of the flange attains the value prescribed for the product. The radius r shall match that prescribed for the product. |

3. 環(huán)拉伸試驗 3.1 長度約15mm處的管截面應(yīng)具有平而光滑的末端,應(yīng)與管軸具有正確的角度。進行該試驗,在拉伸測試機上用2個直徑等于至少3倍管壁厚的銷拉伸管截面直到發(fā)生斷裂,見圖2.10。對于焊接管,試件放置在拉伸測試機時應(yīng)使焊縫與拉伸載荷方向保持90°。 銷的速率不應(yīng)超過5mm/s。 4. 擴口試驗 4.1 進行該試驗,將錐形擴孔器強行伸進試件,直到外徑增加到產(chǎn)品規(guī)定的C值,見圖2.11。試件的長度和擴孔器的錐角β如下表所示。錐體的進入速率不應(yīng)超過50mm/s。 5. 翻邊試驗 5.1 進行該試驗,在圖2.12所示的裝置將一個長度=1.5D的管樣件加工成法蘭,直到法蘭的外徑C達到產(chǎn)品的規(guī)定值。 半徑r應(yīng)符合產(chǎn)品規(guī)定。 |
