Xariiqda dhuumaha API oo leh birta kaarboon
Tuubada dhuumaha API waxay ka tirsan tahay heerarka batroolka ANSI.Shaqada dhuumaha xadhkaha ayaa ah in lagu shubo saliidda, gaaska, biyaha garoonka ilaa warshadda sifaynta.
Tuubooyinka dhuumaha waxaa ka mid ah tuubo aan fiicneyn iyo tuubo alxan leh.Horumarinta tignoolajiyada saxanka birta ee dhuumaha iyo farsamada alxanka waxay balaadhiyaan baaxadda codsiga ee tuubooyinka alxanka.
Gaar ahaan tuubada birta dhexroorka weyn, tuubada tuubada welded waxay leedahay faa'iido aan la barbar dhigi karin.
Tilmaamaha dhuumaha API:
1) Habka habka: Dhuumaha birta ERW, Dhuumaha steek LSAW, Dhuumaha birta SSAW, Cold barbaro, Hot giringiriyey, DSAW
2) Dhamaadka dusha sare: Rinjiga Varnish Coating
3) Heerarka iyo Qalabka:API 5L,API 5CT A, B, X42, X46, X52, X56, X60, X65, X70, X80 5L B, X42, X52 & API 5CT ASTM A106 GR B ASTM A53 GR B
4) Size: OD 33.4mm - 914mm tuubo bir ah oo aan kala go 'lahayn, 323.8mm -1420mm ee tuubada birta LSAW, 219mm -3120mm
5) Dhammaadka Dhamaystirka: Dhammaadka bacaadka ah ama dhammaan darafyada
7) Codsiyada: gudbinta saliidda iyo gaaska fog, dhuumaha gaadiidka dareeraha ah
8) Ereyga xirxirida: Baakadaha caadiga ah ee badda, xirxirida farabadan guud
API 5L X60 birta birta ah
Tilmaamaha darajada API 5L X60 PSL 1 waxay ka yimaaddaan API Spec 5L Specification for Line Pipe.Darajooyinka adag waxay leeyihiin calaamadda X oo ay ku xigto awoodda wax-soo-saarka ugu yar ee birta tuubada, oo lagu qiyaasay kilopounds halkii inji oo labajibbaaran (la soo gaabiyey ksi).Heerka Line Pipe wuxuu leeyahay calaamadaynta darajada A iyo B.
Codsiga: gaaska, biyaha iyo gaadiidka saliidda ee saliidda iyo gaaska dabiiciga ah labadaba.
