Isikhokelo samaBanga e-H Beam Steel: Imigangatho ye-ASTM, EN, kunye ne-GB icacisiwe

Kwishishini lezakhiwo neziseko zophuhliso kwihlabathi liphela, kubalulekile ukukhetha izixhobo zokwakha ezifanelekileyo ukuze kukhuseleke, kuhlale ixesha elide kwaye kusetyenziswe kakuhle.Umthengisi we-H Beam,Yazi imigangatho yeNtsimbi evela kwihlabathi liphela - iMigangatho yaMazwe ngaMazwe yeNtsimbi - i-ASTM (yaseMelika), i-EN (yaseYurophu), i-GB (yaseTshayina) - Iinjineli kunye nabathengi kufuneka babe nokuqonda okucacileyo.

Esi sikhokelo sibonelela ngohlalutyo olupheleleyo lwezona ntlobo zentsimbi ziqhelekileyo ezisetyenziswa yiI-Carbon Steel H BeamAbavelisi kwihlabathi liphela.

Imigangatho ye-ASTM (eMntla Melika)

I-American Society for Testing and Materials (ASTM) ibeka umlinganiselo weprojekthi ezininzi kwiNtshona yeHlabathi.

Umqadi we-ASTM A36 H: Eyona ntlobo yentsimbi "ethambileyo" esetyenziswa kakhulu. Ubuncinane yi-36 ksi (250 MPa), amandla ayo aphezulu kwaye inokudityaniswa kakuhle kunye nokuguquguquka okwenza ukuba ibe yenye yezona ntsimbi zibalaseleyo zokwakha ngokubanzi kunye neendibano zebholti.

I-A572 H Beam (Ibanga lama-50): Intsimbi ye-High Strength Low Alloy (HSLA). Amandla aphezulu okuvelisa (50 ksi / 345 MPa) ye-A572 H beam xa ithelekiswa ne-A36 ivumela ukusetyenziswa kwamacandelo alula kumthwalo ofanayo, ngaloo ndlela igcina ubunzima beprojekthi iyonke.

Umqadi we-A992 H: Eyona ndlela isetyenziswa kakhulu kwimiqadi ebanzi eMelika oza kuyifumana namhlanje. Yikhemistri eyahlukileyo, eyenzelwe ukuphucula ukuwelda kunye nomlinganiselo omncinci we-yield-to-tensile kwizicelo ze-seismic.

Imigangatho ye-EN (iYurophu)

Umgangatho waseYurophu (Umqadi we-EN 10025 H) isebenzisa indlela yokubiza amagama esekelwe kumandla amancinci okuvelisa izinto kwiMegapascals (MPa).

Umqadi we-S235JR H: Uhlobo lwaseYurophu lwe-A36. Inamandla okuvelisa angama-235 MPa. Igama elithi "JR" livela kwinto yokuba intsimbi iye yavavanywa kubushushu begumbi (20°C).

Umqadi we-S275JR H: Intsimbi yesakhiwo esiphakathi (amandla okuvelisa = 275 MPa). Isetyenziswa kakhulu kwizakhiwo zeebhulorho nakwizixhobo ezinzima.

Umqadi we-S355JR H: I-High Strength S355JR Steel Beam yeyona isetyenziswa kakhulu kwiibhari ezinamandla aphezulu kwikhathalogu ye-EN. Ngomlinganiselo wamandla okuvelisa we-355 MPa, ikwayeyona nto ikhethwayo kwizakhiwo eziphakamileyo kunye nezakhiwo ezikude nolwandle apho ubunzima kunye nobukhulu bemilinganiselo bubalulekile.

Imigangatho ye-GB (eTshayina)

Njengoko iTshayina isengumvelisi omkhulu kwihlabathi, uninziIntsimbi yeCarbonAbaboneleli be-H Beamlandela umgangatho we-GB/T 11263.

Umqadi we-Q235 H: Ifana ne-S235JR kunye ne-A36. Uphawu "Q" kwi-Q235 lumele inqanaba le-yield ngelixa i-235 ibonisa amandla kwi-MPa. Ikwasetyenziswa rhoqo kwizakhiwo zesibini kunye neenqaba zonxibelelwano.

Umqadi we-Q355 H: Ilandela i-Q345 yakudala, le yeyona nto iphambili kwiziseko zophuhliso zaseTshayina. Yaziwa njenge-S355JR equivalent, esetyenziswa kakhulu kwizakhiwo zentsimbi ezilungisiweyo kwangaphambili (PEB) nakwizityalo ezinkulu zoshishino.

Umthengisi weFektri yeH Beam

Kutheni Kubalulekile Ukukhetha Umthengisi we-H Beam Ofanelekileyo

Ukuze ukwazi ukuhamba kule migangatho, udinga iqabane elinolwazi lokuqinisekisa ukuwela imida.Abavelisi be-H Beamngoku banikezela ngeeMill Test Certificates (MTC) ezibonisa "iDual Certificate;" umqadi unokuqinisekiswa kwi-S355JR kunye ne-Q355 ngaxeshanye.

Nokuba indawo yakho yokugcina impahla iseMexico, ibhulorho yakho ikwiPhilippines, Ukukhetha umgangatho ofanelekileyo womsebenzi kunika uxolo lwengqondo ekwazini ukuba umsebenzi awuyi kuba semgangathweni nje kuphela kodwa uya kuba luncedo kakhulu kwibhajethi yakho yezinto eziphathekayo.
