Tuubada API 5L waxaa loola jeedaa tuubo bir ah oo kaarboon ah oo loo isticmaalo nidaamyada gudbinta saliidda iyo gaaska. Waxaa sidoo kale loo isticmaalaa in lagu qaado dareerayaasha kale sida uumiga, biyaha, iyo dhoobada.

Noocyada Wax-soo-saarka

Qeexitaanka API 5L wuxuu daboolayaa noocyada wax soo saarka ee la alxamay iyo kuwa aan kala go 'lahayn.

Noocyada Alxanka: ERW, SAW, DSAW, LSAW, SSAW, Tuubada HSAW

Noocyada caadiga ah ee biibiile alxanka API 5L waa sida soo socota:

ERWAlxanka iska caabbinta korontada, oo caadi ahaan loo isticmaalo dhexroorka tuubooyinka oo ka yar 24 inji.

DSAW/SAWAlxanka qaansada ee laba-geesoodka ah/alxanka qaansada ee biyaha hoostooda ku jira, hab alxan oo kale oo loo isticmaalo tuubooyinka dhexroorka weyn.

LSAWAlxanka qulqulka dheer ee biyaha hoostooda ku jira, oo loo isticmaalo dhexroorka tuubooyinka ilaa 48 inji. Sidoo kale loo yaqaan habka wax soo saarka JCOE.

SSAW/HSAWAlxanka qaansada ee ku wareegsan/alxanka qaansada ee ku wareegsan, oo loo isticmaalo dhexroorka tuubooyinka ilaa 100 inji.

Nala soo xiriir si aad u ogaato faraqa u dhexeeya tuubooyinka ERW, LSAW, iyo SSAW.

Noocyada Tuubooyinka aan Tolmada Lahayn: Tuubbo aan Tolmada Lahayn oo Kulul iyo Tuubbo aan Tolmada Lahayn oo Qabow

Tuubo aan tolnayn ayaa badanaa loo isticmaalaa tuubooyinka dhexroorkoodu yar yahay (badanaa ka yar 24 inji).

(Tuubo bir ah oo aan tolnayn ayaa si caadi ah loo isticmaalaa marka loo eego tuubooyinka la alxamay ee dhexroorka tuubooyinka ka yar 150 mm (6 inji).

Waxaan sidoo kale bixinnaa tuubo dhexroorkeedu weyn yahay oo aan lahayn wax cillad ah. Annagoo adeegsanayna habka wax soo saarka kulul ee la duubay, waxaan soo saari karnaa tuubo aan cillad lahayn oo dhexroorkeedu yahay 20 inji (508 mm). Haddii aad u baahan tahay tuubo aan cillad lahayn oo ka weyn dhexroorkeedu yahay 20 inji, waxaan ku soo saari karnaa iyadoo la adeegsanayo hab kulul oo la ballaariyay oo dhexroorkiisu yahay 40 inji (1016 mm).

Heerka Tuubada API 5L

API 5L wuxuu daboolayaa Darajada B, X42, X46, X52, X56, X60, X65, X70, iyo X80.

Tuubada birta ah ee API 5L waxay isticmaashaa darajooyin bir ah oo kala duwan, oo ay ku jiraan Darajada B, X42, X46, X52, X56, X60, X65, X70, iyo X80. Marka heerka birta uu kordho, xakamaynta u dhiganta kaarboonku way sii adkaanaysaa sifooyinka xoogga farsamadana way sii kordhayaan.

Intaa waxaa dheer, isku-dhafka kiimikada ee tuubooyinka API 5L ee aan kala go 'lahayn iyo kuwa la alxamay ee isku heerka birta ah way kala duwan yihiin, iyadoo tuubooyinka alxamay ay leeyihiin shuruudo adag iyo waxyaabo kaarboon iyo sulfur hooseeya.

Heerka Tilmaamaha: PSL1, PSL2

PSL waxay u taagan tahay Heerka Sharaxaadda Badeecada, oo ay ku jiraan PSL1 iyo PSL2. Waxaa sidoo kale loo fahmi karaa inay tahay darajo tayo leh.

PSL1 iyo PSL2 kuma kala duwana oo keliya shuruudaha tijaabada laakiin sidoo kale waxay ku kala duwan yihiin halabuurka kiimikada iyo sifooyinka farsamada.

PSL2 waxay leedahay shuruudo ka adag PSL1 marka loo eego halabuurka kiimikada, sifooyinka la riixo, tijaabada saameynta, tijaabada aan burburin, iwm.

Tijaabada Saamaynta
PSL1 uma baahna baaritaanka saameynta, halka PSL2 (marka laga reebo X80) ay u baahan tahay.

Tijaabin aan burburin
PSL1 uma baahna tijaabo aan burburin, halka PSL2 u baahan tahay tijaabo aan burburin.

(Tijaabinta aan burburin: Tijaabinta iyo tijaabinta aan burburin ee heerka API 5L waxay isticmaashaa raajada, ultrasonic, ama habab kale (iyada oo aan la burburin agabka) si loo ogaado cilladaha iyo cilladaha ku jira dhuumaha.)
