Anggapoy Tahi ya Asero ya Tubo

Anggapoy tahi ya asero ya tuboginawa so tuboanggapoy welded seam. Nagawa iya diad pamapainit ed sakey a malet ya asero,itusok itan pian magmaliw ya abot, insan i-roll tan i-size so tubo ed nakaukolan ya OD tan kapal na dingding antis ya sumpalen (heat treatment, end prep, tan final inspection) ed tinukoy mon estandarte tan grado.

Say Octal Pipe et akasentro ed sayan klase na kimey. Mansusuplay kami na seamless steel pipe ya walaan na nanduruman estandarte ed interon mundo –API 5L line pipe, ASTM A106 / A53 parad proseso na tubo,A179/ A213 parad boiler tan heat-exchanger tubes, A335 parad alloy high-temperature service, tan EN 10216 tan saray misiglaotan ya GB/T ya grado. Say sukat na bintana et mansakbong10.3–1422 mm ODtan saray kapal na dingding ya anggad150 mm, kanian saray linya na transmisyon, boiler tubes, exchanger bundles tan saray structural members et nayarin naala edsakey a nantutumbokan ya anggapoy problemaimbes ya naapag ed pigaran gilingan.

Diad benegan na kada kabaleg tan grado et walay kontroladonrota na produksyon: mandrel- odino plug-mill rolling, defined heat treatment, full dimensional checks tan inmabobon ed NDT / hydrotest scope. Kada batch et nipalapag ya walayEN 10204 3.1 o 3.2 ya sertipiko tan sigpot ya heat traceability, ya mangiiter ed saray project engineers, QA tan third-party inspectors na malinew ya audit trail tan mamapaabeba ed peligro na last-minute rework odino hold-ups diad pinal ya aprobasyon.
