Nawa ne Nauyin Bututun ƙarfe na Ductile

A fannin samar da ruwa da magudanar ruwa, hanyoyin sadarwa na bututun birni, da tsarin bututun masana'antu,bututun ƙarfe mai ductileya zama madadin bututun ƙarfe da ƙarfe na gargajiya saboda kyawawan halayen injina da juriyar tsatsa. Fahimtar mahimman sigogin fasaha na bututun ƙarfe mai ductile yana da mahimmanci ga masu zane, masu siye, da kamfanonin gini, ko don hanyoyin samar da ruwa ko jigilar najasa. Wannan labarin zai ɗaukibututun ƙarfe na DINSEN ductilea matsayin misali don bayyana takamaiman aikinsa, nauyinsa, matsin lamba na aiki, da halayen rufinsa cikin tsari.

I. Bayani dalla-dalla game da Bututun ƙarfe na Ductile da Girmansa: Yadda ake tantance samfurin?

Lokacin zabar bututu, da farko ya zama dole a fayyace girma da girman bututun ƙarfe mai ductile. Ka'idojin ƙasa da ƙasa galibi sun dogara ne akan ISO 2531 ko EN 545, waɗanda aka rarraba ta hanyar diamita mai suna (DN).

Idan aka yi la'akari da bututun ƙarfe na DINSEN ductile a matsayin misali, ana amfani da bututun K9 (matakin kauri na bango na yau da kullun), tare da diamita mai suna daga DN80 zuwa DN2000. Ga wasu girman bututun da aka saba amfani da su:

• DN80: Diamita na waje 98mm, kauri bango 6.0mm
• DN100: Diamita na waje 118mm, kauri bango 6.0mm
• DN200: Diamita na waje 222mm, kauri na bango 6.3mm
• DN400: Diamita na waje 429mm, kauri bango 8.1mm
• DN1000: Diamita na waje 1048mm, kauri bango 13.5mm

Ma'auni daban-daban na kauri bango (K8, K9, K10, K12) zasu shafi ƙarfin ɗaukar matsi da nauyin naúrar bututunMasu amfani za su iya zaɓar yadda ya kamata bisa ga matsin lamba na ƙira.

II. Nauyi a kowace mita na bututun ƙarfe mai ductile: Nawa ne nauyin bututun ƙarfe mai ductile?

Tambayar da aka saba yi a fannin siyan injiniyoyi ita ce: Nawa ne nauyin bututun ƙarfe na ductile? Nauyin bututun ƙarfe na ductile ya ƙunshi nauyin jikin bututun da nauyin soket ɗin, wanda ke shafar kai tsaye ga sufuri, ɗagawa, da kuɗin shigarwa.

Idan aka ɗauki bututun ƙarfe mai ƙarfi na DINSEN K9 (tsawon mita 6) a matsayin misali, nauyin ka'idar kamar haka:

• DN100: Kimanin 15.1 kg/m → 95 kg a kowace bututu
• DN200: Kimanin 30.6 kg/m → 194 kg a kowace bututu
• DN300: Kimanin 50.8 kg/m → 323 kg a kowace bututu
• DN500: Kimanin 104.3 kg/m → 669 kg a kowace bututu
• DN800: Kimanin 215.2 kg/m → 1394 kg a kowace bututu

Nauyin gaske na iya bambanta kaɗan saboda abubuwa kamar kauri na rufin zinc da rufin turmi na ciki. DINSEN na iya samar da takaddun lissafin nauyi daidai don kasafin kuɗi na ayyuka da tsara dabaru.

III. Matsi na Bututun ƙarfe mai ƙarfi na Ductile

Bututun ƙarfe na Ductile yana da ƙarfin jurewa da ƙarfin matsewa. Bututun ƙarfe na Ductile na K9 na yau da kullun yawanci yana da matsin lamba na aiki na sanduna 16 (1.6 MPa), yayin da matakan kauri na bango mafi girma (kamar K12) sun dace da amfani da matsi na sanduna 25 ko ma sanduna 40.

Ana ƙera bututun ƙarfe na DINSEN ductile bisa ƙa'idodin ISO 2531. Kowace bututu ana yin gwajin hydrostatic kafin ta bar masana'antar don tabbatar da cewa akwai ma'aunin tsaro sau 1.5 fiye da matsin lamba na ƙira, wanda hakan ya sa suka dace musamman don watsa ruwa mai nisa, bututun famfo na tashar tashi, da bututun masana'antu masu matsin lamba mai yawa.

IV. Rufin Zinc don Kariyar Tsatsa

Matsayin Rufin Zinc akan Bututun ƙarfe na Ductile Ɗaya daga cikin mahimman matakan kariya ga bututun da aka binne shine rufin zinc akan bututun ƙarfe na ductile. Rufin zinc ba wai kawai yana ba da kariya daga cathodic ba har ma yana samar da tsarin hana lalata tare da fenti na waje ko rufin polyethylene.

Bututun ƙarfe na DINSEN ductile suna zuwa daidai da murfin zinc na ≥200 g/m² (bisa ga ƙa'idar ISO 8179), an rufe su da jan kwalta ko layin gamawa na polyurethane, wanda ke inganta juriyar tsatsa da tsawon rai. Ga ƙasa mai lalata ko wuraren da ke da juriya mai yawa, akwai ƙarin murfin zinc + fim ɗin PE ko cikakken murfin polyurethane, tare da tsara tsawon shekaru 50-100.

V. Me Yasa Zabi Bututun ƙarfe na DINSEN Ductile?

A matsayina na ƙwararren mai samar da bututun ƙarfe mai ƙarfi, DINSEN tana ba da cikakkun bayanai daga DN80 zuwa DN2000, tana tallafawa kauri daban-daban na bango kamar K8, K9, K10, da K12, kuma tana iya keɓance tsayi, layukan ciki (turmi/resin epoxy), da kuma hanyoyin kariya daga tsatsa don biyan buƙatun abokin ciniki.

Duk bututun bututun ƙarfe an tabbatar da su ta ISO 2531 / EN 545. Cikakken teburi na nauyi, girma, matsin lamba na aiki, da sigogin rufin zinc suna nan. Ana tallafawa marufi na fitarwa na ƙasashen waje da ayyukan jigilar kaya na tsayawa ɗaya.

Don ƙarin cikakkun bayanai game da girman bututun ƙarfe da tebura na zaɓin girma ko kayan aikin lissafin nauyi, don Allah ziyarciDINSENko kuma a tuntuɓi ƙungiyar tallace-tallace ta fasaha kai tsaye.
