F. Technological Tests on Pipes 1. Pipe flattening test 1.1 To perform this test, a section of pipe equal in length to 1,5 times the pipe diameter, but not less than 10 mm and not more than 100 mm, is flattened between two plates to the prescribed distance H, see Chapter 2 – Steel and Iron Materials, Section 2, A.8.5 or until fracture occurs, see Figure 2.8. In the case of welded pipes, the specimen shall be placed in the press in such a manner that the seam is set at 90° to the direction of the pressure, unless agreed otherwise. 1.2 After the test, the specimens shall be thoroughly examined for defects with normal visual acuity. The test shall be satisfactory if the specimen, having been flattened to the prescribed distance, is free from cracks and did not fracture. The dimensions of the pipe section, the distance H between the flattening plates as well as the position of the welding joint are to be stated. 2. Ring expanding test 2.1 To perform this test, sections of pipe measuring 10 to 16 mm in length L are expanded to the prescribed diameter C or until fracture occurs using a drift with a taper of about 1:5. Where necessary, more than one test shall be performed with drifts of increasing diameter. The superimposition of several specimens of the same size and steel grade is permitted, see Figure 2.9. |

F. 管材測(cè)試技術(shù) 1. 管壓扁試驗(yàn) 1.1在這個(gè)測(cè)試中,長度為1至5倍管道直徑的管道節(jié),不短于10mm且不超過100mm,被兩個(gè)平面擠壓至距離距離H,第二章——鋼鐵材料,第二節(jié), A.8.5部分;或者直至發(fā)生斷裂,如圖2.8所示。對(duì)焊接法制造的鋼管,試樣應(yīng)放置在這樣一種方式使得焊縫設(shè)定在與壓力成90°的方向,除非另有商定。 1.2試驗(yàn)后,應(yīng)用常規(guī)視覺方法徹底檢查標(biāo)本缺陷。 滿意的實(shí)驗(yàn)是如果試樣被壓扁至規(guī)定的距離,沒有見到裂隙、沒有發(fā)生斷裂, 管道節(jié)的尺寸,壓扁板之間的距離H以及焊接接頭的位置都應(yīng)有記錄。 2. 環(huán)錐撐脹測(cè)試 2.1 在這個(gè)測(cè)試中,長度L為10-16mm的測(cè)試樣品管將被一個(gè)錐度*為1/5的模塊撐脹至預(yù)定的內(nèi)徑C。必要時(shí),可采用多個(gè)口徑遞次增加的模塊完成實(shí)驗(yàn)。相同尺寸和鋼種材料的交疊是允許的,如圖2.9所示。 * 錐度=(大端直徑-小端直徑)/高 |
