API 5L Steel Line Pipe Plate

Inkcazelo emfutshane:

Intsimbi yombhobho luhlobo lwepleyiti yentsimbi esetyenziselwa imibhobho, esetyenziswa ikakhulu ekwenzeni imibhobho ye-oyile kunye negesi yendalo, kunye namalahle kunye nodaka lwempahla yokwakha.Intsimbi ayifuni kuphela amandla oxinzelelo oluphezulu, kodwa ikwafuna ukuqina kobushushu obuphantsi kunye nokuqina okugqwesileyo.

Intshayelelo yeMveliso

Insimbi yombhobho yanamhlanje yintsimbi ephantsi-carbon okanye i-ultra-low-carbon microalloyed steel, eyimveliso enomxholo ophezulu wobugcisa kunye nexabiso eliphezulu elongezelelweyo.Uninzi lweempumelelo zeteknoloji entsha kwintsimi ye-metallurgical kwiminyaka eyi-20 edlulileyo isetyenziswe kwimveliso yentsimbi yombhobho.Umkhwa wophuhliso wobunjineli bemibhobho yidayamitha yombhobho omkhulu, ukuthuthwa kwerhasi enoxinzelelo oluphezulu, ukupholisa okuphezulu, indawo yokusetyenziswa kwe-corrosion ephezulu, kunye nobukhulu bodonga lombhobho ongaphantsi kolwandle.Ke ngoko, intsimbi yanamhlanje yombhobho kufuneka ibe namandla aphezulu, isiphumo esisezantsi se-Bauschinger, ukuqina okuphezulu kunye nokumelana nokuqina, umxholo wekhabhoni ye-weld ephantsi kunye ne-weldability elungileyo, kunye nokuchasana ne-HIC kunye ne-H2S corrosion.

Ipleyiti yentsimbi yombhobho isetyenziselwa ukwenza imibhobho yomgca odityanisiweyo, kuba imibhobho yemigca engenamthungo yenziwe ngebhari engqukuva, hayi iipleyiti zentsimbi.Ipleyiti eshinyeneyo ephakathi isetyenziswa ngokubanzi ukuvelisa umbhobho odityanisiweyo wodonga oluthe tye oluthe tye, kwaye intsimbi yekhoyili isetyenziselwa ukuvelisa umbhobho wombane we-resistane welded(ERW) kunye nombhobho ontywilisiweyo we-arc odityanisiweyo (SSAW).Namhlanje, abathengi abaninzi bafuna ipleyiti yentsimbi yombhobho ukuvelisa imibhobho yomgca kuba iipleyiti zentsimbi zingasetyenziselwa ukwenza imibhobho emikhulu edayamitha, ukongeza, ixabiso lemibhobho edityanisiweyo lihlala lisezantsi kunelo lemibhobho engenamthungo.

Ipleyiti yentsimbi yombhobho yomgca yinto ephambili yokuvelisa umbhobho womgca we-ERW, umbhobho womgca we-LSAW, umbhobho womgca we-SSAW, osetyenziselwa ukwakhiwa komgca wepayipi kwi-oyile, igesi kunye nokuthutha amanzi, ingasetyenziselwa ukuvelisa ukwakhiwa kokuhanjiswa kwamanzi oxinzelelo.

Amaqondo obushushu asezantsi kakhulu e-arctic, uxinzelelo olumandla kulwandle olunzulu, imidiya ye-asidi: nezona meko zimbi kakhulu azinampembelelo imbi kwiipleyiti zethu zombhobho.Iipleyiti zombhobho ziyakwazi ukusebenza kubunzulu obufikelela kuma-2,800 eemitha ngaphantsi komphezulu wolwandle.

Sikwabonelela ngepleyiti yentsimbi yolwakhiwo oludityanisiweyo kunye nolwakhiwo olumelana nomhlwa kwiimfuno eziphezulu zegesi emuncu.Njengengcali kwitekhnoloji ye-thermo yokuqengqeleka koomatshini ngokupholisa okukhawulezileyo, siphakathi kweenkokheli zeshishini zehlabathi.
