Qarqoor Carabta ISO 2531 | Dhexeystiran & Eegga Arrimaha Ku Caran

Dhulka badbaadaha ISO 2531 waa la mid ahayd badbaadaha dhulka ka horaystiran International Organization for Standardization (ISO) 2531, oo ay ku jiraan raadinta dhexeeya ah ee badbaadaha dhulka aad ugu yaraan inuu ka soo dirir kartaa si sharciga ah ee badbaadaha dhulka ee ku saabsan dhalinyarada iyo xaaladda koor. Sharcigaas waa in laga heli karo sharciyada tekniska ku covin doonaa macluumaadka carruurta, xawaareedka mekanikal, proseska ka horaystiran, iyo taabtooyinka badbaadaha haddii u baahan yihiin qaybta carruurta iyo xogga badbaadaha. Haddii tahay carruurta, badbaadaha dhulka ISO 2531 waxaa lagu yimid si caafimaad ah carruur, silisayn, manganees, iyo carruur kale ee ku yaal magnesium iyo carruur reer kuur, oo ay ku sameyn doonaa in ay ku siiyo grafki ee shaqo ah ee ku daran nodules. Waxbarasho khas oo ka mid ah ay ku nool kartaa qoraxda stress, kuwaas oo la hayo tensile strength (koodu ≥420 MPa), yield strength (≥300 MPa), iyo elongation (≥10%), oo ay ku sameyn doonaa inuu ku jirin qorax dheeraad ah iyo loadka ka dib marka uu ku jira pipeline systems. Prosesska ka horaystiran waa in lagu yimid casting gudbiyaal, oo ay ku sameyn doonaa inuu ka socdo carruur badbadaha iyo lacag guud ah, si aad ugu yahay heat treatment oo ay ku sameyn doonaa xawaareedka mekanikal. Xiriiradda badbaadaha, sababtoo ah zinc spraying iyo bituminous coating, ayaa la kulmayaa corosion resistance, iyo lacagta lacagta ah ee ku yimid cement mortar iyo epoxy resin ayaa la kulmayaa hygiene ee dhalinyarada transportation. Badbaadaha ISO 2531 waxaa la yidhaahda qofku waxaa la abaalbadanayo networkka dhalinyarada ka mid ah ee ka mid ah, plants ee xanaano koor, iyo industrial drainage systems ee ku jira dunida. Carruurtaas iyo sharciyada joogga (sida flexible rubber ring joints) ayaa la kulmayaa installation ee ahista ah iyo adkaadinta ground settlement ama seismic activities. Raadintaas ee la hayo global recognition ayaa la kulmayaa procurement ee projects internationals, oo ay ku sameyn doonaa compatibility iyo interchangeability. Markaasaa uu ururka dhexeeya ah ee ku jira, maxaa yeelay developing countries, demandka badbaadaha ISO 2531 ee ku jira raadinta ayaa lagu sameyn doonaa, sidoo kale oo ku jira dependability iyo service life koonfiya.
