    isicelo

    Oku ikakhulu kusetyenziswa ukwenza carbon ezikumgangatho ophezulu zokwakha, ingxubevange zokwakha kunye nemibhobho stainless olungenazimfanta kuhlinzwa ubushushu-resistant uxinzelelo oluphezulu nangaphezulu imibhobho kwibhoyila umphunga.

    ezisetyenziselwa ikakhulu uxinzelelo ophezulu kunye nenkonzo eliphezulu lobushushu kwibhoyila (Superheater ityhubhu, reheater tube, isikhokelo umoya tube, ityhubhu umphunga esingundoqo boilers eziphakamileyo ultra koxinzelelo oluphezulu). Phantsi isenzo lobushushu eliphezulu igesi ulwelo kunye nomphunga wamanzi, ityhubhu uya oxidize kunye ezinokudla. Kulindeleke ukuba umbhobho sentsimbi lwale ihlala phezulu, ukumelana phezulu ukuya igcwala umhlwa, kunye nozinzo entle.

    Except for Q345A and Q345B grades, the steel should contain at least one of the refined grain elements Al, Nb, V, and Ti. According to the needs, the supplier can add one or more refined grain elements, the maximum value Should meet the requirements in the table. When combined, Nb + V + Ti <0.22% °For Q345, Q390, Q420 and Q46O grades, Mo + Cr <0.30% oWhen each grade of Cr and Ni is used as the residual element, the content of Cr and Ni should not be more than 0.30%; when it needs to be added, its content should meet the requirements in the table or be determined by the supplier and the buyer through consultation.

    J Ukuba umthengisi unako ukuqinisekisa ukuba umxholo nitrogen uyahlangabezana neemfuneko kwitheyibhile, uhlalutyo lomxholo nitrogen akufunekanga ukwenziwa. Ukuba Al, yesiqephu, V, Ti kunye nezinye izinto ingxubevange kunye nitrogen nitrogen ezidityaniswe ngentsimbi, isiqulatho nitrogen kuphela. Umxholo kuba ngundaba-nitrogen kufuneka zicaciswe kwisiqinisekiso esemgangathweni.

    ubude:

    Ubude zisaqhubeka Imibhobho ephakathi yentsimbi yi-4 000 mm ~ 12 000 mm. Emva kothetha-thethwano phakathi umthengisi kunye nomthengi, kunye fill kule mvumelwano, oko kuhlangulwa imibhobho kuhlinzwa omkhulu ubude kwama-12 000 mm okanye elifutshane kunokuba 000 mm kodwa mfutshane kwe-3 000 mm; ubude emfutshane Inani lemibhobho zentsimbi ngaphantsi kwama-4,000 mm kodwa hayi ngaphantsi kwe 3,000 mm aluyi kuba ngaphezu kwe-5% yenani lilonke Imibhobho ephakathi yentsimbi kusiwa

    Ubunzima Delivery:
    Xa umbhobho intsimbi le nto mayihanjiswe ukuya enobubanzi engaphandle nencinane nodonga ubukhulu okanye enobubanzi yangaphakathi nencinane udonga ubukhulu, umbhobho intsimbi le nto mayihanjiswe ubunzima eyiyo. Kananjalo kusiwa ubunzima theoretical component.
    Xa umbhobho steel le nto mayihanjiswe eliyimali engaphandle ubukhulu kunye ubuncinane udonga ubukhulu, umbhobho intsimbi le nto mayihanjiswe ubunzima eyiyo; amaqela sonikezelo kunye nemfuno ezingxoxweni. Kwaye oko kubonisiwe kwisivumelwano. Umbhobho steel kwakhona kusiwa ubunzima theoretical component.

    Ubunzima ukunyamezelana:
    Ngokutsho iimfuno salowo uyithengileyo, emva kokubonisana phakathi umthengisi kunye umthengi, kwaye kule mvumelwano, ukuphambuka phakathi ubunzima yokoqobo ubunzima nemiqathango umbhobho sentsimbi unikezelo iya kuhlangana ezi mfuno zilandelayo:
    a) sentsimbi Single pipe: ± 10%;
    b) Ibhetshi nganye ngemibhobho kuhlinzwa ubukhulu ubuncinane 10 t: ± 7.5%.

    test Izidingo

    Hydraustatic Test:

    Umbhobho steel kufuneka avavanywe hydraulically enye kwenye. Uxinzelelo iphezulu vavanyo 20 MPA. Phantsi uxinzelelo test, ixesha uzinziso kufuneka ungabi ngaphantsi kwe-10 ubudala, nogwali intsimbi kufuneka kugquma.

    Emva kokuba umsebenzisi uyavuma, uvavanyo hydraulic singavalwa ngokuhlola eddy ngoku okanye uvavanyo ngemagnethi ukuvuza ukubhobhoza.

    Test Nondestructive:

    Imibhobho ezifuna uhlolo ngakumbi kufuneka ultrasonically zihlolwe nganye nganye. Emva kokuba thethwano kufuna imvume zeqela kwaye kucacisiwe isivumelwano, enye uvavanyo non-etshabalalisayo inokongezwa.

    Flattening Test:

    Ngemibhobho kunye ubukhulu enkulu engaphandle kwe-22 mm oyakuphathwa gadalala uvavanyo flattening. Akukho delamination ebonakalayo, amatshatshazi amhlophe, okanye ubumdaka kufuneka kwenzeke ngexesha lonke nokuhlola.

    Lokudlabhuka Test:

     Ngokutsho iimfuno salowo uyithengileyo kwaye kuchaziwe kwisivumelwano, umbhobho intsimbi kunye ≤76mm ubukhulu engaphandle nodonga ubukhulu ≤8mm kunokwenziwa lokudlabhuka uvavanyo. Le lokulinga kwenziwa bushushu kunye Taper-60 °. Emva kokuba lokudlabhuka, izinga lokudlabhuka le ubukhulu engaphandle kufuneka ihlangabezane neemfuno theyibhile ilandelayo, kwaye ke izinto uvavanyo kufuneka ubonise iintanda okanye rips
