Isingeniso sePinetha se-Api 5l

I-API 5LNgokuvamile kubhekiswa epayipi lensimbi yepayipi (ipayipi lepayipi) lokuqaliswa kweZinga, Pipelineipayipi lensimbikufaka phakathi ipayipi lensimbi engenamthungo kanye ne-welded yensimbi izigaba ezimbili. Njengamanje epayipini lamafutha sivame ukusebenzisa uhlobo lwe-welded lwensimbi yepayipi luwukufika kwe-arc welded pied (I-SSAW), ipayipi eliqonde ngqo le-arcLsaw), Ukumelana ne-Welding Pipe (Edwa), Ipayipi lensimbi engenamthungokuvame ukusetshenziswa kububanzi bepayipi kungaphansi kwe-152mm.

I-National Standard GB / T 971112011 Ipayipi lensimbi yohlelo lokuhamba lwamapayipi embonini kawoyela negesi lihlanganiswe ngokusho kwe-API 5L.

I-GB / T 9711-2011 icacisa izidingo zokukhiqiza zamapayipi ensimbi angenamthungo nama-welded amazinga amabili omkhiqizo (PSL1 nePSL2) ngezinhlelo zokuhamba zePipeline embonini kawoyela negesi. Ngakho-ke, indinganiso isebenza kuphela kumapayipi ensimbi engenamthungo kanye namapayipi ensimbi afakwe ama-welded for uwoyela nokuhamba kwegesi, futhi awasebenzi kumapayipi e-Iron.

Amamaki ensimbi

Amamaki ensimbi wezinto ezingavuthiwe zamapayipi ensimbi ale API 5l ejwayelekile yi-GR.B, x42, x46, x60, x56, x60, x50, x60, x50, x60, x56, x60, x56, x60, x50, x60, x50, x60, x50, x60, x50, x60 Futhi ukukhiqizwa futhi kuhlukile, kepha okufana nekhabhoni phakathi kwamabanga ahlukile kulawulwa ngokuphelele.

 

Izinga lekhwalithi

Ku-API 5l Pipeal Ejwayelekile, amazinga wekhwalithi (noma izidingo) ngepayipi lensimbi ahlukaniswe nge-PSL1 nePSL2. I-PSL yisifinyezo sezinga lokucaciswa komkhiqizo.

I-PSL1 ihlinzeka ngezinga elijwayelekile lezidingo zekhwalithi yepayipi; I-PSL2 ingeza izidingo eziphoqelekile zokwakheka kwamakhemikhali, ubulukhuni obunamahloni, izakhiwo zamandla, nama-NDes angeziwe.
