Yintoni i-STPT 370 Pipe Material?

STPT 370libakala lomgangatho waseJapan iJIS G 3456 kwimibhobho yentsimbi yekhabhoni, esetyenziselwa imibhobho yoxinzelelo kwindawo ezinamaqondo obushushu angaphezu kwama-350°C.Isenokuba yimibhobho engenamthungo okanye edityanisiweyo kusetyenziswa inkqubo yokumelana nombane (ERW).Iimpawu zemishini ye-STPT 370 yempahla yincinci yamandla angaphantsi kwe-370 MPa kunye namandla amancinci angama-215 MPa.

Ukuba ukhangele umenzi kunye nomthengisi wemibhobho yensimbi edibana nomgangatho we-JIS G 3456, ngoko singumlingani owufunayo.Qhagamshelana nathi namhlanje kwaye siya kukuvuyela ukukunceda!

Uluhlu lweDimension

Ifanelekile kwii-diameters zangaphandle 10.5 mm - 660.4 mm (6A - 650A) (1/8B - 26B).

U-A no-B ziindlela ezimbini zokubonisa i-diameter yegama kumgangatho waseJapan.Ngokukodwa, u-A uhambelana ne-DN, ngelixa u-B ehambelana ne-NPS.

Inkqubo yokuVelisa

I-JIS G 3456 STPT 370 inokuveliswa ngokusebenzisa iengenamthungoinkqubo yokuvelisa okanye iukuwelda ukuxhathisa kombane(ERW) inkqubo.

Inkqubo yokuvelisa iphinda ihambelane neendlela ezahlukeneyo zokugqiba ukujamelana neendawo ezahlukeneyo zokusetyenziswa.

Unyango lobushushu

I-STPT 370 kufuneka iphathwe ngobushushu.

1. Umbhobho wensimbi ongenamthungo ogqityiweyo ogqityiweyo: Njengoko wenziwe I-annealing yobushushu obuphantsi okanye i-normalizing ingasetyenziswa njengoko kufuneka;

2. Umbhobho wensimbi ongenamthungo ogqityiweyo obandayo: I-annealing yobushushu obuphantsi okanye i-normalizing;

3. Umbhobho wentsimbi odityanisiweyo ogqityiweyo oshushu ogqityiweyo: Njengoko wenziwe I-annealing yobushushu obuphantsi okanye i-normalizing ingasetyenziswa njengoko kufuneka;

4. Ukuchasana kombane okubandayo okugqityiweyo okudityanisiweyo kunye Njengokumelana nombane welded steel pipe: Ukushisa okuphantsi kwe-annealing okanye ukuqhelekileyo.

Ipropati yoKutyabeka

Ifanelekile imibhobho enobubanzi obungaphandle obungaphezulu kwe-60.5 mm.

Lo mzekelo ubekwe phakathi kwamaqonga amabini kwaye ucandwe.Xa umgama phakathi kwamacwecwe amabini ufikelelaH, akukho zintanda kumphezulu we-specimen yombhobho wensimbi.

H = 1.08t/(0.08+ t/D)

н: umgama phakathi kweeplatens (mm);

t: ubukhulu bodonga lombhobho (mm);

D: ngaphandle kobubanzi bombhobho (mm);

Ukubanda

Ifanelekile kwimibhobho yensimbi kunye nobubanzi obungaphandle be-60.5 mm okanye ngaphantsi.

Xa umboniso ugobile malunga ne-mandrel ukuya kwi-radius yangaphakathi ka-6 ububanzi obungaphandle bombhobho, i-specimen ihlolwe kwaye akukho zintanda zifunyenwe.

Xa i-diameter yangaphandle kunye nobukhulu bodonga lombhobho wentsimbi ayibobukhulu obuqhelekileyo, ezi ndlela zilandelayo zingasetyenziselwa ukumisela ibakala elifanelekileyo lokuchazwa:

Okokuqala, khetha ibakala leshedyuli eliqhelekileyo elikufutshane nobungakanani obungalinganiyo;okwesibini, misela ibakala lokubala ngokubala ixabiso le-P.

Kuzo zombini iindlela, ixabiso elincinci kufuneka likhethwe njengebakala lokugqibela lenkcazo.

P = 2st/D

P: uxinzelelo lovavanyo (MPa);

t: ubukhulu bodonga lombhobho (mm);

D: ngaphandle kobubanzi bombhobho (mm);

s: 60% yexabiso eliphantsi elichaziweyo lenqaku lesivuno okanye ubungqina boxinzelelo;

Uvavanyo olungonakalisi

Iindlela eziqhelekileyo zovavanyo ezingonakalisi zibandakanya uvavanyo lwe-ultrasonic (UT) kunye novavanyo lwangoku lwe-eddy (ET).

Xa usenza uhlolo lwe-ultrasonic, ireferensi kufuneka yenziwe kwi-JIS G 0582, kwaye xa umphumo wokuhlola ulingana okanye udlula umgangatho wokubhekisela kwiklasi ye-UD, kuthathwa njengokungaphumeleli.

Xa usenza uhlolo lwangoku lwe-eddy, ireferensi kufuneka yenziwe kwi-JIS G 0583. Xa isiphumo sokuhlolwa silingana okanye sidlula umgangatho wereferensi yeklasi ye-EY, ithathwa njengengafanelekanga.
