Nekuti mapaipi akajairika mumaindasitiri akawanda, hazvishamisi kuti masangano akasiyana-siyana emitemo anokanganisa kugadzirwa uye kuyedzwa kwemapaipi kuti ashandiswe mumhando dzakasiyana-siyana dzemashandisirwo.
Sezvamuchaona, pane zvimwe zvinhu zvakafanana pamwe chete nemisiyano pakati pemasangano emitemo ayo vatengi vanofanira kunzwisisa kuitira kuti vagone kuve nechokwadi chekuti mapurojekiti avo akagadzirwa nemazvo.
1. ASTM
ASTM International inopa zvigadziro zvemaindasitiri uye masevhisi muzvikamu zvakasiyana-siyana zvemaindasitiri. Sangano iri rakaburitsa zviyero zvinopfuura 12,000 zviri kushandiswa mumaindasitiri pasi rese parizvino.
Zvinopfuura zana zvezviyero izvi zvine chekuita nemapaipi esimbi, machubhu, mafittings uye maflanges. Kusiyana nemamwe masangano ezviyero anokanganisa mapaipi esimbi muzvikamu zvemaindasitiri, zviyero zveASTM zvinofukidza mhando dzakasiyana dzemapaipi anoshandiswa muindasitiri yega yega yaunogona kufunga nezvayo.
Semuenzaniso, American Piping Products ine mapaipi eA106 akasiyana-siyana. A106 standard inovhara mapaipi esimbi yekabhoni isina musono kuti ishandiswe pakupisa kwakanyanya. Mutemo iwoyo haurevi kuti mapaipi anofanira kushandiswa mumaindasitiri chete.
2. ASME
Sangano reAmerican Society of Mechanical Engineers rakatanga kuburitsa mitemo yezvishandiso zvemaindasitiri nezvikamu zvemuchina muna 1880 uye rave riri simba guru rekuvandudza kuchengetedzeka kwemaboiler nemidziyo yepressure inoshandiswa mumaindasitiri ese.
Sezvo mapaipi achiwanzo famba nemidziyo yekumanikidza, zviyero zveASME zvinofukidza mashandisirwo akasiyana-siyana emapombi mumaindasitiri akawanda, seASTM. Kutaura zvazviri, zviyero zvemapaipi zveASME neASTM zvakafanana zvakanyanya. Chero nguva paunoona chiyero chepaipi chinoratidzwa ne'A' ne'SA'—muenzaniso iA/SA 333—chiratidzo chekuti chinhu chacho chinosangana nezvinodiwa zveASTM neASME.
3. API
Sezvinoratidzwa nezita rayo, American Petroleum Institute isangano rakanangana neindasitiri, pakati pezvimwe zvinhu, rinogadzira uye rinoburitsa mwero wemapaipi nezvimwe zvinoshandiswa muindasitiri yemafuta negasi.
Mapaipi akayerwa pasi pechiyero cheAPI anogona kufanana zvakanyanya muzvinhu uye magadzirirwo nemapaipi anoshandiswa mune mamwe maindasitiri pasi pezvimwe zviyero. Mitemo yeAPI yakaoma uye inosanganisira zvimwe zvinodiwa pakuyedza, asi pane zvimwe zvinoenderana.
Semuenzaniso, pombi yeAPI 5L inowanzoshandiswa munzvimbo dzemafuta negasi. Mutemo uyu wakafanana neA/SA 106 neA/SA 53. Mamwe magiredhi epombi yeAPI 5L anotevedzera mitemo yeA/SA 106 neA/SA 53 uye anogona kushandiswa achichinjana. Asi pombi yeA/SA 106 neA/SA 53 haitevedzere mitemo yese yeAPI 5L.
4. ANSI
Sangano reAmerican National Standards Institute rakavambwa mushure mekuungana kwemasangano akati wandei emitemo yeindasitiri muna 1916 nechinangwa chekugadzira mitemo yekubvumirana kwevanhu muUS.
ANSI yakabatana nemasangano akafanana mune dzimwe nyika kuti vaumbe International Organisation for Standardization (ISO). Sangano iri rinoburitsa mitemo inogamuchirwa nevanobatana nemaindasitiri kubva pasi rese. ANSI inoshandawo sesangano rinopa mvumo inotsigira mitemo yakagadzirwa nemasangano ega ega kuti ishandiswe pasi rose.
ASTM, ASME nedzimwe nhanho dzakatsigirwa neANSI senzira dzinogamuchirwa. Muenzaniso mumwe ndeweASME B16 standard yemaflanges, mavharuvhu, mafittings uye magaskets. Standard iyi yakatanga kugadzirwa neASME, asi yakatenderwa kushandiswa pasi rese neANSI.
Kuedza kweANSI kwakabatsira kuvhura misika yepasi rose yevagadziri nevatengesi vemapombi nekuda kwebasa rayo mukuvandudza nekugamuchira mitemo yakafanana inogamuchirwa pasi rose.
5. Mupi wepombi akakodzera
Nemakore akawanda eruzivo rwekupa mapaipi kuvatengi vemaindasitiri ese pasi rese, Jindalai Steel Group inonzwisisa kuomarara uye kukosha kwezviyero zvakawanda zvinotonga kugadzirwa nekuyedzwa kwemapaipi. Ngatishandisei ruzivo irworwo kuti bhizinesi renyu ribudirire. Nekusarudza Jindalai semutengesi wenyu, munogona kutarisa pane zvinonyanya kukosha kwamuri pane kunyura muzvinhu zvakawanda. Mapaipi esimbi eJindalai anogona kusangana nezviyero zvese zvataurwa pamusoro apa.
Kana uchida kutenga, kumbira mutengo. Tichakupa imwe inokutorera zvinhu zvaunoda nekukurumidza. Tumira mubvunzo wako uye tichafara kukubvunza nehunyanzvi.
