Pipa Jalur
Dipaké pikeun conveying gas, cai, jeung minyak dina duanana jeung industri gas alam jsb.
Casing: Casing mangrupakeun pipa diaméterna badag anu boga fungsi minangka retainer struktural pikeun dinding sumur minyak jeung gas, atawa sumur bore.It diselapkeun kana sumur bore na cemented di tempat pikeun ngajaga duanana formasi subsurface jeung wellbore ti runtuhna jeung pikeun ngidinan cairan pangeboran sirkulasi jeung ékstraksi lumangsung.Pipa Casing Steel gaduh témbok lemes & kakuatan ngahasilkeun minimum 35,000 psi.
Tubing: Tubing mangrupikeun pipa anu dianggo pikeun ngangkut minyak bumi sareng gas alam tina lapisan minyak atanapi gas ka permukaan saatos pangeboran réngsé.Éta dijieun pikeun tahan tekanan dihasilkeun tina prosés ékstraksi.Tubing dijieun dina cara nu sarua salaku casing, iwal hiji prosés tambahan katelah "upsetting" dilarapkeun ka thicken pipa.
