Ulwazi Olwengeziwe

Ichweba Lokuthunyelwa Ngemikhumbi: Tianjin, China.
Imigomo Yokukhokha:T / T, LC.
Ukulethwa: izinsuku ezingu-7-15 ngemva kokukhokha.
Umphezulu: Amashubhu azovanishwa (Ngaphandle kuphela) ukuvimbela ukugqwala.
Ukumaka: Ibanga Elijwayelekile + Lensimbi + Usayizi + Nokushisa No + Lot No.
Iphakheji: Izinqwaba (ezinehexagonal), Amabhokisi Okhuni, Amakhreyithi (insimbi/ukhuni) noma njengoba kudingeka.

Izindlela Zokukhiqiza

(1)Indlela yokukhiqiza insimbi
Insimbi yenziwa ngesithando somlilo sikagesi, isiguquli se-oxygen noma indlela yeziko elivulekile.

(2)Indlela yokukhiqiza yeshubhu elingenalutho
I-tube blank ingenziwa ngendlela eshisayo yokugoqa, futhi i-billet eqhubekayo yokuphonsa noma ingot yensimbi nayo ingasetshenziswa.

(3)Indlela yokukhiqiza yepayipi lensimbi
Ipayipi lensimbi lingenziwa ngokugoqa okushisayo (i-extrusion, ukunwetshwa) noma umdwebo obandayo (ukugoqa) indlela engenamthungo.

Ukuhlolwa

(1)Ukuhlolwa kwe-hydraulic
Ipayipi lensimbi kufanele lihlolwe nge-hydraulically ngalinye.

(2)Ukuhlolwa kokuthambisa
Amapayipi ensimbi anobubanzi obungaphandle obungaphezu kuka-22mm kuya ku-400mm kanye nogqinsi olungeqile ku-10mm azohlolwa ukuze kube isicaba.

(3)Ukuhlola okuvuthayo
Ipayipi yensimbi enobukhulu bodonga obungekho ngaphezu kuka-8 mm ingafakwa ngaphansi kokuhlolwa kwe-flare nge-taper ephezulu ye-30 °, 45 ° noma 60 °.

(4) Ukuhlolwa kokugoba
Amapayipi ensimbi anobubanzi obungaphandle obungeqile ku-22 mm azohlolwa ngokugoba.

(5)Ukuhlola okungabhubhisi
Ngokwezidingo zomthengi, ipayipi lensimbi lizohlolwa nge-ultrasonically ngayinye.

Ikhwalithi Yobuso

Izindawo zangaphakathi nezangaphandle zepayipi lensimbi azinakho ukuqhekeka, ukugoqa, ama-creases, i-crusting noma ukuhlukaniswa, futhi lezi ziphambeko kufanele zisuswe ngokuphelele.Ukujula kokususa akumele kudlule ukuchezuka okunegethivu kogqinsi oluvamile lodonga, futhi ukujiya kwangempela kodonga endaweni yokuhlanza akumele kube ngaphansi kobuncane obuvunyelwe udonga.
