(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.

(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 alulazeke.
(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.
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 ubukhulu bodonga lwangempela endaweni yokuhlanza akumele bube buncane kunobuncane obuvunyelwe udonga.
Ukupakishwa, ukumaka kanye nokucaciswa kwekhwalithi yamapayipi ensimbi kuzohambisana nezinhlinzeko ze-GB/T 2102.
Sinamathela "kwikhwalithi ephezulu, ukulethwa okufika ngesikhathi, intengo yokuncintisana", namakhasimende asekhaya nawakwamanye amazwe ukusungula ubudlelwano bokubambisana besikhathi eside, uchungechunge lwemikhiqizo yethu luye lwanconywa amakhasimende amasha namadala, sizoqondisa amakhasimende ngendlela efanele ukusebenzisa. imikhiqizo yethu kanye nezixazululo zokusetshenziswa kobuchwepheshe, kanye nendlela yokukhetha izinto ezifanele.
Ngemikhiqizo eminingi yaseShayina nezisombululo ezisakazwa emhlabeni wonke, ibhizinisi lethu lamazwe ngamazwe liye lathuthuka ngokushesha futhi izinkomba zezomnotho zanda kakhulu unyaka nonyaka.Manje siqiniseka ngokwanele ukukunikeza izimpahla namasevisi angcono ngoba sikhula sinamandla, sinobuchwepheshe ngokwengeziwe futhi sinolwazi oluthe xaxa kokubili ngaphakathi nangaphandle.
