Kumvetsetsa Ubwino wa Chitoliro cha Chitsulo cha ASTM A139 cha Mapaipi a Gasi Wachilengedwe Omwe Ali Pansi pa Dziko

Yambitsani:

Ponena za mayendedwe a gasi wachilengedwe, kufunika kwa mapaipi apansi panthaka sikunganyalanyazidwe. Mapaipi awa amatsimikizira kuti mphamvu yofunikayi imapezeka m'nyumba, mabizinesi ndi mafakitale mosamala komanso moyenera. Kuti mapaipi awa akhale olimba, odalirika komanso olimba, kugwiritsa ntchito zipangizo zapamwamba ndikofunikira. Pakati pa njira zambiri zomwe zilipo,ASTM A139Chitoliro chachitsulo chozungulira chimadziwika kuti ndi chisankho chapadera. Mu blog iyi, tikambirana za mawonekedwe ndi ubwino womwe umapangitsa ASTM A139 kukhala chinthu chosankhidwa kwambiri pa mapaipi a gasi wachilengedwe pansi pa nthaka.

Kapangidwe ka Mankhwala

Mayeso a Hydrostatic

Kutalika kulikonse kwa chitoliro kuyenera kuyesedwa ndi wopanga ku mphamvu ya hydrostatic yomwe ingapangitse kuti pakhoma la chitoliro pakhale mphamvu yosachepera 60% ya mphamvu yocheperako yopezeka pa kutentha kwa chipinda. Kupanikizika kuyenera kutsimikiziridwa ndi equation yotsatirayi:
P=2St/D

Kusintha Kovomerezeka kwa Kulemera ndi Miyeso

Utali uliwonse wa chitoliro uyenera kuyezedwa padera ndipo kulemera kwake sikuyenera kupitirira 10% kapena 5.5% pansi pa kulemera kwake kongopeka, kuwerengedwa pogwiritsa ntchito kutalika kwake ndi kulemera kwake pa unit level.
M'mimba mwake wakunja suyenera kusiyana kuposa ± 1% kuchokera m'mimba mwake wakunja womwe watchulidwa.
Kukhuthala kwa khoma nthawi iliyonse sikuyenera kupitirira 12.5% ​​pansi pa makulidwe a khoma omwe atchulidwa.

Utali

Kutalika kwapadera: 16 mpaka 25ft (4.88 mpaka 7.62m)
Kutalika kawiri mwachisawawa: kuposa 25ft mpaka 35ft (7.62 mpaka 10.67m)
Kutalika kofanana: kusiyanasiyana kovomerezeka ± 1in

Mapeto

Mapaipi ayenera kukhala ndi malekezero osawoneka bwino, ndipo ma burrs omwe ali kumapeto ayenera kuchotsedwa.
Pamene mapeto a chitoliro atchulidwa kuti ndi malekezero a bevel, ngodya iyenera kukhala madigiri 30 mpaka 35.

ASTM A139: Kusankhidwa kwaChitoliro cha Gasi Wachilengedwe Pansi pa Pansimizere:

1. Mphamvu ndi kulimba:

ASTM A139chitoliro chachitsulo chozunguliraimadziwika ndi mphamvu zake zabwino kwambiri zokoka komanso kugwedezeka. Makhalidwe amenewa ndi ofunikira kwambiri pa mapaipi a gasi achilengedwe a pansi pa nthaka chifukwa nthawi zonse amakhala ndi mavuto osiyanasiyana a chilengedwe komanso pansi pa nthaka. Kapangidwe ka chitoliro chachitsulo kamawonjezera kulimba kwake, zomwe zimathandiza kuti chizitha kupirira kupsinjika kwakukulu kwakunja ndikuchepetsa chiopsezo cha kutuluka kapena kuphulika.

2. Kukana dzimbiri:

Mapaipi apansi panthaka amatha kugwidwa ndi dzimbiri chifukwa cha madzi, mankhwala a nthaka ndi zinthu zina. Chitoliro chachitsulo chozungulira cha ASTM A139 chimathetsa vutoli popereka kukana dzimbiri kwambiri. Izi zimachitika makamaka chifukwa cha utoto wake wokhala ndi zinc yambiri, womwe umapereka chotchinga choteteza ku zinthu zowononga, kuonetsetsa kuti chitolirocho chikhalapo kwa nthawi yayitali komanso kuchepetsa kufunikira kokonza kapena kusintha pafupipafupi.

3. Kutha kupotoza ndi kusinthasintha:

Chitoliro chachitsulo chozungulira cha ASTM A139 chili ndi kuthekera kolumikizana bwino kwambiri, zomwe zimathandiza kuti malo olumikizira azikhala osalala komanso ogwira ntchito bwino panthawi yoyika. Mbali imeneyi ndi yothandiza kwambiri pamapaipi a gasi achilengedwe apansi pa nthaka, chifukwa zimaonetsetsa kuti mapaipi ali olimba komanso zimachepetsa chiopsezo cha kutuluka kwa madzi. Kuphatikiza apo, kusinthasintha kwa chitoliro chachitsulo chozungulira kumalola kuti chipangidwe mosavuta m'mautali ndi m'mimba mwake osiyanasiyana kuti chikwaniritse zofunikira zosiyanasiyana za polojekiti, motero zimathandiza kuti pakhale ndalama zotsika mtengo komanso kusintha zinthu.

4. Kugwiritsa ntchito bwino ndalama:

Ubwino wina waukulu wogwiritsa ntchito chitoliro chachitsulo cha ASTM A139 pa mapaipi a gasi achilengedwe apansi panthaka ndi wokwera mtengo. Kulimba kwa chipangizocho, kukana dzimbiri komanso kusavuta kuyika kumachepetsa ndalama zosamalira ndi kusintha kwa nthawi yayitali. Kuphatikiza apo, chiŵerengero chake champhamvu kwambiri pakati pa kulemera ndi kulemera chimachepetsa kufunikira kwa nyumba zambiri zothandizira panthawi yoyika, zomwe zimapangitsa kuti ndalama zonse zisungidwe.

5. Zinthu zofunika kuziganizira pa chilengedwe:

Chitoliro chachitsulo chozungulira cha ASTM A139 chimapangidwa pogwiritsa ntchito njira zosamalira chilengedwe ndipo chimatsatira miyezo yokhwima yachitetezo. Kapangidwe kake kosagwira dzimbiri kumathandiza kupewa kutuluka kwa mpweya, zomwe pamapeto pake zimachepetsa kuwonongeka kwa chilengedwe. Kuphatikiza apo, kubwezeretsanso kwa chitsulocho kumapangitsa kuti chikhale chosamalira chilengedwe, zomwe zikugogomezeranso ubwino wokhazikika wogwiritsa ntchito chitoliro chachitsulo chozungulira cha ASTM A139 pamapaipi a gasi achilengedwe apansi panthaka.

Pomaliza:

Kusankha zipangizo zoyenera zogwiritsira ntchito mapaipi a gasi wachilengedwe pansi pa nthaka ndikofunikira kwambiri kuti zitsimikizire kuti mphamvu yamtengo wapatali iyi ikuyenda bwino, moyenera komanso modalirika. Chitoliro chachitsulo cha ASTM A139 ndi chisankho chabwino kwambiri chifukwa cha mphamvu zake, kulimba kwake, kukana dzimbiri, kusinthasintha, kugwiritsa ntchito bwino ndalama, komanso kuganizira za chilengedwe. Kapangidwe kake kapadera kamapangitsa kuti chikhale chisankho choyamba kwa mainjiniya ndi oyang'anira mapulojekiti omwe akufuna kumanga mapaipi a gasi wachilengedwe pansi pa nthaka omwe adzakhalebe olimba kwa nthawi yayitali. Mwa kuyika ndalama pazinthu zabwino monga chitoliro chachitsulo cha ASTM A139, titha kutsimikizira kuti pali malo osungira gasi wachilengedwe okhazikika komanso otetezeka kwa mibadwo ikubwerayi.
