I. Waa maxay maaddaduAPI5L
1. API5L-B birta dhuunta, oo u dhiganta L245 brand Wuyang Iron iyo birta, L245 waxay iska leedahay taxanaha alloy hooseeya, qiimuhu waa mid aad u sarreeya, qiimaha alaabta kala duwan maaha mid isku mid ah, inta badan loo isticmaalo dhuumaha saliidda, dhuumaha dabiiciga ah, iwm
2. Maadada waadarajada X52 dhuunta birta birtaline steel, kaas oo ah nooc bir ah oo leh shuruudo gaar ah oo loo isticmaalo gudbinta saliidda iyo dhuumaha gaaska dabiiciga ah.Marka loo eego dhumucda iyo samaynta ku xigta, waxaa lagu soo saari karaa warshad duuban oo joogto ah, foorno duuban ama warshad dhumuc dhexdhexaad ah oo loo sameeyay tuubo bir dhexroor weyn leh alxanka wareega ama UOE alxanka tol toosan.
3. Dhuumaha birta ah ee aan xidhnayn ama alxanka leh, heerku waaAPI 5L (tuubada dhuumaha) PSL2waa mid ka mid ah darajooyinka, kan kalena waa PSL1 marka la barbardhigo, shuruudaha PSL2 way ka sarreeyaan PSL1API 5L waa qeexida dhuumaha dhuumaha ee uu sameeyay Machadka Batroolka Maraykanka, B waa mid ka mid ah darajooyinka birta dhuumaha.
II.API5L heerka
Heerka 1.API5L, tirada kala-goysyada birta PIPE iyo PIPE WLD 10" SCH STD API5L ASTM A106 GRB tuubooyinka birta ee isku midka ah waa inaysan ka badnayn 50% tirada tuubooyinka. Kahor intaan la rakibin, tuubada tuubada waa inay xaaqin Nadiifi godadka daloolka ama hawada cadaadiska sare si aad u hubiso in daloolka (dalooluhu aanu ka yarayn 127cm) uu buuxiyo shuruudaha kana hortagayo daloolka.
3. (%) : hoos u dhigista acuity ee bedka 18 bits (%) : 45 ama ka sareeya saamaynta tamarta Akv (J): 55 ama ka sareeya saamaynta adkaanta qiimaha alfa kv (J/cm2).
Heerka 3.API 5L wuxuu daboolayaa shuruudaha wax soo saarka ee birta dhuumaha, gaar ahaan xoogga xajinta, xoogga wax-soo-saarka, adkaanta heerkulka qolka, dhererka nasashada, iwm. Dhuumaha birta, oo ay ku jiraan tuubooyinka birta guud waxay u kala qaybsan yihiin birta caadiga ah iyo tuubada birta xoogga badan, heerka API 5L wuxuu kaloo daboolayaa shuruudaha habka wax soo saarka ee birta dhuumaha.
III, waa maxay walxaha API5Lgrb
1. API 5LGRB waa mid aan toos ahayn amaDhuumaha birta welded, Halbeeggu waa API 5L (tuubada batroolka), PSL2 waa mid ka mid ah heerarka, heerka kale waa PSL1 marka la barbardhigo, PSL2 shuruudaha way ka sarreeyaan PSL1API 5L waa qeexida dhuumaha dhuumaha ee ay soo saartay Machadka Batroolka Maraykanka, B waa nooc. ee darajada birta dhuumaha.
2.ASME SA517, ASTM A517 weelka cadaadiska Demiyay oo dabcay taarikada birta birta ah ee xoogga sare ee ASME SA517/SA517M waxaa ka mid ah: SA517GrA, SA517GrB, SA517GrH, SA517GrS, SA517GrP, SA517GrF, SA517GrF, SA517GrF, SA517Heerka ASTM A517/A517M waxaa ka mid ah: A517GrA,.
3. SahaydaAPI 5L PSL2heerkatuubo bir ah oo wareeg ahGrB-X70 Dhexroorka dibadda 219-3650 mm Salaan, waxaan soo saarnay dhuumaha wareega muddo 24 sano ah, waxaan rajeyneynaa inaan fursad u helno inaan kula shaqeyno.
