Tambayoyin da Ake Yawan Yi (Tambayoyin da Ake Yawan Yi) - ASTM A252 GR.3 SSAW Karfe Bututun Tarin
T: Menene bambanci tsakanin SSAW da LSAW don bututun tara ruwa?
A: SSAW (Spiral Submerged Arc Welded) yana amfani da tsarin walda mai karkace, wanda ya dace da manyan diamita (508mm-3,000mm) da kuma sirara zuwa matsakaiciyar bango. LSAW (Longitudinal Submerged Arc Welded) yana amfani da walda madaidaiciyar dinki, wanda ya fi kyau ga ƙananan diamita (508mm-1,500mm) da kuma kauri bango (har zuwa 50.8mm). SSAW gabaɗaya ya fi araha ga aikace-aikacen tarin diamita mai girma, yayin da LSAW yana ba da ingantaccen daidaiton dinki na walda don aikace-aikacen bango mai kauri.
T: Menene zoben ƙarfe na hadaya kuma yaushe ya kamata a yi amfani da shi?
A: Zoben ƙarfe na hadaya wani ɗan gajeren sashe ne na ƙarfe (yawanci faɗinsa ya kai milimita 50-100, kaurinsa ya kai milimita 6-12, bututun da ya dace da shi OD) wanda aka haɗa shi da ƙarshen bututun da ke tuƙawa. Yana shan kuzarin tasiri daga gudumar tuƙawa, yana kare ƙarshen bututun daga lalacewa, busawa, ko fashewa. Ana ba da shawarar zoben hadaya don yanayin tuƙi mai wahala (yashi mai yawa, tsakuwa, soket na dutse), guduma masu nauyi na tuƙawa, bututun sirara na bango, ayyuka masu mahimmanci inda lalacewar ƙarshen bututu zai haifar da jinkiri a jadawalin aiki, da bututun da ke buƙatar hana ruwa shiga bayan tuƙi.
T: Waɗanne zaɓuɓɓukan tsayi ne ake da su don bututun ASTM A252 GR.3 SSAW mai tara kaya?
A: Tsawon da aka saba da shi shine mita 6, mita 12, da mita 18. Don zurfin ayyukan tushe da na ruwa, muna samar da tsayin da aka keɓance har zuwa mita 60 (ƙafa 200) dangane da diamita da kauri na bango. Tsawon da aka ƙara yana ba da fa'idodi masu mahimmanci: raguwar adadin haɗin filin (ƙarancin farashin shigarwa, jadawalin sauri), ingantaccen ci gaba da tsarin, da rage haɗarin lahani na walda. Duk da haka, tsawon da ya fi tsayi yana buƙatar jigilar kaya ta musamman (kwantenan rack mai faɗi, manyan jiragen ruwa, ko kayan aiki) kuma yana iya samun ƙarin farashin jigilar kaya.
T: Waɗanne zaɓuɓɓukan rufewa ne ake da su don bututun tara ruwa don kare shi daga lalata ruwan teku?
A: Muna bayar da zaɓuɓɓukan rufewa da yawa don hana lalata muhallin ruwa: FBE (Fusion Bonded Epoxy) Layer ɗaya ko biyu, 3LPE/3LPP (Three Layer Polyethylene/Polypropylene), Coal Tar Epoxy, Hot Dip Galvanizing, Liquid Epoxy, da Concrete Weight Coating (CWC). Ga yawancin aikace-aikacen tuƙin ruwa, murfin 3LPE ko FBE tare da kariyar cathodic shine ma'aunin masana'antu.
T: Za ku iya samar da bututun da ke ɗauke da bututun tare da duba na ɓangare na uku (SGS, BV, TÜV, DNV, LR)?
A: Eh. Muna maraba da kuma sauƙaƙe dubawa daga DNV, BV, SGS, TÜV, ABS, LR, ko duk wani wakili da abokin ciniki ya zaɓa yayin samarwa da kuma kafin jigilar kaya. 3.2 Takaddun shaida na dubawa waɗanda hukumomin wasu kamfanoni masu izini suka tabbatar ana bayar da su akai-akai idan an buƙata.
T: Wane gwaji mara lalatawa (NDT) aka tanadar wa bututun ASTM A252 GR.3 SSAW mai tarin abubuwa?
A: Tsarin NDT na yau da kullun ya haɗa da gwajin Ultrasonic 100% (UT) na jikin dinkin walda da bututu, tare da duba tabo na Gwajin Radiography (RT). Ana samun MPI, Gwajin Hydrostatic, da ƙarin UT akan buƙata. Don aikace-aikacen ruwa masu mahimmanci, muna ba da shawarar 100% RT ko cikakken UT.
T: Menene lokacin jagora na yau da kullun don bututun ASTM A252 GR.3 SSAW?
A: Lokacin da aka saba amfani da shi wajen samar da SSAW yana da kimanin kwanaki 30-45, ya danganta da yawan oda, diamita, kauri na bango, da kuma buƙatun gwaji. Umarnin gaggawa (kwanaki 20-30) na iya samuwa ga ƙananan adadi. Don ayyukan da ke buƙatar dubawa na ɓangare na uku, ƙara kwanaki 5-10. Don shafa (FBE, 3LPE, da sauransu), ƙara kwanaki 10-20.
T: Waɗanne takardu ne aka bayar game da kowace jigilar kaya?
A: Kowace jigilar kaya ta ƙunshi Takaddun Shaidar Gwajin Injin (EN 10204 Type 3.1), Rahoton Duba Girma, Rahotannin UT, Rahotannin RT (idan an ƙayyade), Takardun Bibiyar Aiki, Jerin Marufi, Takardar Kuɗin Kasuwanci, da Takaddun Asali. Ga ƙa'idodin EN, ana iya bayar da sanarwar alamar CE da Sanarwar Aiki (DoP)
