Five-star hotel tam tak standard-ah chuan tui supply system atan copper pipe hman a ngai a, mahse a man leh market avang a nih avangin tunah chuan hotel tam zawkin stainless steel pipe hman an pawm ta a ni. He thuziak hian copper pipe leh stainless steel pipe te chu technical comparison a siam ber a ni. ,reference atan.
1. Copper pipe leh stainless steel pipe tehkhin dan .
Tunah chuan taksa hnathawh dan, faina hnathawh dan, corrosion resistance leh economic value te khaikhin rawh.
1) Physical property te khaikhin dan .
Tensile strength tehkhin dan:
Entirna atan 304-a siam thin, walled stainless steel pipe thin-walled hman tlanglawn tak chu la la, a tensile strength chu 530-750mpa a ni a, hei hi galvanized pipe aiin a let hnih a ni a, copper pipe aiin a let thum zetin a sang zawk bawk. Chuvangin, thin-walled stainless steel pipe chu copper pipe aiin thinner (0.6mm) a siam theih a ni a, hei hi national industrial policy of saving materials nen a inmil a, strength guarantee a nei a, buildings load-bearing tihtlem tumna a nei thei a ni.
2) Thermal conductivity tehkhin dan:
Thin-walled stainless steel pipe thermal conductivity chu 15 W/m°C (100°C) a ni a, hei hi carbon steel pipe atanga 1/4 leh copper pipe atanga 1/23 a ni. Thin-wall stainless steel pipe te hi an thermal insulation performance tha tak avangin tui lum phurh nan a tha hle. Insulation layer thickness emaw, insulation structure siam leh enkawl man emaw pawh nise, thin-wall stainless steel pipe te hian economical efficiency tha tak an nei a ni.
3) Thermal expansion coefficient hrang hrangte khaikhin dan:
Thin-walled stainless steel pipe-a thermal expansion-a coefficient average chu 0.017mm/(m°C) a ni a, hei hi copper pipe-te nen a inhnaih hle. Tui lum phurh nan hian metal pipe hman tur a ni.
Thin-walled stainless steel tube chhung lam bang chu a chhung leh pawn lam finishing treatment hnuah a nem a, a chhunga wall wall-a roughness ks tlukpui chu 0.00152mm a ni a, chu chu copper tube aiin a te zawk a ni.
Chuvangin, thin-walled stainless steel pipe hman hian tui a luang tam zawk a, tui a luang tha zawk a, corrosion resistance a nei tha zawk a, a ri pawh a ti tlem tha hle bawk.
2. Faina hnathawh dan tehkhin dan .
Stainless steel tui pipe hian 'red water, blue-green water leh tui thup' buaina chu a ti bo a'. A rim danglam lo, scaling a nei lo va, thil hlauhawm tak tak precipitation a nei lo va, tui quality a thianghlim a, mihring taksa tan pawh a hlauhawm lo.
Kum sawm tam tak chhunga ram hrang hrang hman dan leh ram hrang hranga laboratory test-naah chuan stainless steel metal elements precipitation chu WHO leh European Drinking Water Act-in standard value an siam zinga 5% aia tam a ni tih a lang (khawvel ram zawng zawng hian heng standard pahnih hi an sawi a ni). Hniam.
Dik tak chuan, stainless steel material ngei pawh hi a him a, a toxic lo a, tihfai theihna tha tak a nei bawk a, chu chu kum sawm tam tak chhunga mihring hriselna nena inzawm field hrang hranga stainless steel hlawhtling taka hman a nih khan a takin a finfiah tawh a, thil hriat hlawh tak a ni ta a ni.
Stainless steel hi ei leh in lama hun rei tak chhung hman a ni tawh lo va, in tur, dairy, brewing, damdawi siamna industry, tableware leh cooking hmanrua te pawh a tel a, heng industry-ah hian standard material a ni tawh a, mahse, medical human implant-ah pawh hman a ni nasa hle a, chu chu bracket hrang hrang, cleaned-a artificial joint leh steel-a steel, leh steel, leh steel-a steel, leh steel-a hman tur ang chi, medical human implant-ah pawh hman a ni nasa hle a ni. Faina a sang hle.
Copper pipe hi a chhe thei a, patina a siam awlsam hle tih chu hriat lar tak a ni.
Copper pipe hian copper tam lutuk a tuar a, a corrosion vangin blue-green water atanga rimchhia, corrosive bitter odor a nei a, scaling a nei bawk. Copper pipe-a awm 'patinous green' hi copper carbonate, copper hydroxide compound [Cuco3.cu(ON)2] leh copper sulfate (CUSO4) atanga siam a ni ber a, chu chu khaw lum leh tuiah a inthiar awlsam hle. Fungi hi a tikhawlo thei a, mahse bacteria effect-ah nghawng a nei lo a, a tha lo a, a toxic a, insecticide atan pawh hman a ni a, chu chuan mihring taksaa mucous membrane-a astringent, stimulating leh corrosive effect a nei a ni.
Reflex vomiting a thlen thei a, intestinal tract-ah stimulating effect nasa tak a nei bawk. Tunlai damdawi lam zirchianna atanga a lan dan chuan copper tam lutuk (blue-green water level a thlen pawhin) hi hriselna atan a hlauhawm hle a ni.
3. Corrosion resistance tehkhin dan .
A chhan chu thin-walled stainless steel tube hian oxidant nen a passivate thei a, chroxium trioxide (CR2O3) chung lamah chromium-rich oxide protective film khauh leh dense tak a siam thei a, hei hian oxidation reaction a thlen belh zel tur a veng thei a, copper tube passivation theihna erawh a tha hle thung. Hei hi copper pipe-te corrosion resistance chu thin-walled stainless steel pipe-te aiin a tlahniam zawk chhan ber a ni.
Copper pipe hman hunah chuan tui chemical composition leh speed control a ngai a, chuti lo chuan pipe te chu a tichhe thei ang. Entirnan, copper pipe-te corrosion chu tuiah nasa takin a pung ang a, pH<6.5 emaw residual chlorine content>70ppm emaw hmangin a pung ang a, tui nem chuan corrosion a tisang bawk ang. Copper pipe hman hunah chuan tui velocity chu 2 m/s aia tam lo tur a ni a, chuti lo chuan corrosion rate chu nasa takin a pung ang.
Flow rate chu 2 m/s a thlen chuan copper pipe-a corrosion degree chu thin-walled stainless steel pipe aiin a let 3 vel a ni a, flow rate chu 6 m/s aia tam a nih chuan, thin-walled stainless steel pipe aiin corrosion degree chu a let 20 zetin a sang zawk ang.
Tin, copper pipe chunglam pawh a chhe awlsam hle bawk.
4. Economic value tehkhin dan .
New York, USA-a awm Chrysler building hi kum 1926 leh 1931 inkar khan sak a ni a, meter 318.9-a sang a ni a, floor 77 a awm a ni. Khawvela a pawn lam a stainless steel material hman hmasak ber a ni.
Coastal leh boruak bawlhhlawh tak tak awmna hmun ni mah se, a chunga stainless steel chu kum 80 hnuah pawh a la eng reng a, a inkar ah hian tihfai vawi hnih chauh a la awm.
New York-a Chrysler building aṭanga Kuala Lumpur-a Petronas Towers aṭanga Los Angeles-a Disney concert hall-a stainless steel hmanga siam a nih thlengin, England-a London-a Waterloo rel station thlengin Structural parts, stainless steel, green building material chhunzawm zel thei ber angin, thil pangngaiin khawvel hmun hrang hranga a neih loh charm danglam tak a pholang a ni.
Hengte hi stainless steel-a hun kal tawha thil awm dan entir tha tak tak an ni.
Ram chhung leh ram pawna thin-walled stainless steel pipe hman dan thlirletna atang chuan thin-walled stainless steel pipe leh tui pipe te service life chu building te nen a inang a, chu chu copper pipe te nen a inang a ni.
A rilru a buai em em a, a rilru a hah em em bawk a.
Meter khata rit = (pawn lam diameter - a thuk) × a thuk zawng × Pi × Density ÷ 1000
Pipe man tehkhin dan: Copper raw material man sang tak avangin copper pipe man hi a sang ber a, thin-walled stainless steel pipe man hi copper pipe man aiin 40% velin a tlawm zawk bawk. Chuvangin, thin-walled stainless steel pipe te economic value chu copper pipe aiin a tha zawk tih a chiang hle.
Thin-walled stainless steel pipe hian copper pipe aiin life cycle cost a nei tlem zawk a ni.
A chhan chu thin-walled stainless steel pipe hman a nih chuan kum 100 chhung nun chhung zawnga thlak a ngai tawh lo a, chutih laiin pipe dangte chuan chutiang service life rei tak chu an thleng thei lo. Building kum 70 chhunga vawi khat an thlak chhung chuan a pumpuiah chuan a man zawng zawng chu a tir lama thin-walled stainless steel pipe leh tui pipe-te investment hmasa ber aiin a let 2 atanga 4 tal a ni ang.
Dik tak chuan stainless steel water pipe thlan hian a tir lama investment a nei tlem hle mai bakah life cycle cost a nei tlem hle bawk. Hei hi stainless steel-a economic advantage lian ber a ni a, chu chu material dangte nen a inmil thei lo.
3. Thuhmahruai .
Stainless steel pipe leh copper pipe pahnih hi tui supply metal pipe quality sang tak a ni. Ram pawna copper man hi a man a tlawm deuh avangin ram pawnah tui supply pipe atan copper pipe hman a tam zawk a, ram pawna hmasawnna hun pawh a rei hle.
Domestic stainless steel pipe siam a nih takah chuan international brand star hotel tam takah chuan stainless steel pipe pawh an hmang tawh bawk. Nakin lawkah chuan stainless steel pipe hman theihna tur ruahmanna chu a zau zawk leh zau zawk chauh a ni ang. Pipe siamtu tam zawk chuan 1000 ah hian an deploy tur a ni. precision stainless steel tube siamna machine chu a rang thei ang bera market luah tur a ni a, leh . Hangao Tech (Seko Machinery) chu i thawhpui rintlak tak a ni ang.
