FAQ
Q1: Wanem samting i kirapim yu long makim namel long AP, BA, MP, na EP bilong ol gutpela 'stainless steel' paip?
A1: Ol bikpela samting we i save kirapim em ol samting we i stap namel long ol samting, rot bilong klinim, mak bilong klinim, na baset. Ol konvensenel indastrial na instramen sistem i save yusim AP; ol lain wantaim lukluk na ol samting bilong klinim i save yusim BA; ol sistem we i klin na i save klinim planti taim i laikim MP; ol 'high-purity' na UHP sistem i save nidim EP wantaim 'defined internal Ra' na ol 'documentation. 304L na 316L gred i save kamap planti long tupela laspela kategori.
Q2: Tupela MP na EP i save daunim 'roughness'. Wanem samting i narapela long praktis?
A2:MP i yusim 'mechanical grinding' na 'polish', na lukluk long 'macroscopic roughness' na lukluk bilong en. EP em i 'electrochemical' na i wok long 'micro-scale, na i save helpim wok bilong klinim, bosim ol pipia, na strongim ol kemikel. Ol 'high-end sistem i save bungim ol dispela: MP long rausim ol 'macro-defects, bihain EP long stretim gut insait bilong en, moa yet long ol 316L 'precision tubes' we i gat 'high-purity' na 'bioprocess' aplikesen.
Q3: Ol tritmen bilong pes i save afektim ol 'dimensional tolerances' na 'geometrical accuracy'?
A3: Yes. Tupela wok, 'mechanical polishing' na 'electropolising' i save rausim ol samting. Long ol liklik-wol o tait-tolerans tiub, ol i mas putim ol alawens long taim bilong disain na kontrolim long prodaksen bai ol pinis presis steinles stiel tiub i stap insait long ol mak bilong OD, WT, na jiometri.
Q4: Em inap long tok "internally electropolished" insait long spesifikesen?
A4: Planti taim nogat. Em i gutpela long makim EP klas, skop (ID o ID+OD), intanel Ra mak, rot bilong skelim, na ol rekot ol i nidim (tritmen, Ra risal, klinim). Dispela i mekim wok bilong wokim samting, sekim, na kisim i stap stret wantaim 'delivery state' tru.
Q5: Bilong wanem 'traceability' em i bikpela samting long ol 'precision 304/316 stainless steel tube' projek?
A5: Trasebiliti (ol namba bilong hat, ol prodaksen bet, ol bet bilong tritim pes, ol rekot bilong inspeksen) i mekim na ol i ken painim hariap ol hevi insait long sevis na ol spesifik materiel o proses kondisen, na i sapotim ol odit na riviu bilong disain bihain. Insait long ol enjiniaring projek, Octal Pipe i save bungim ol dispela data i go long 304/304L na 316/316L MTCs, Ra ripot, na NDT / presa tes rekot insait long wanpela data buk, na kamapim wanpela gutpela kwaliti trel stat long raw materiel i go long pinis presisen tiub.
