Amapayipi e-HSAW (ipayipi elishiselwe i-arc elishiselwe ngaphansi kwamanzi ashisayo), iyinsimbi yensimbi egoqwe eshisayo futhi iyagobeka yakhelwe ngokuzungeza, ukushiselwa kwe-arc okuzenzakalelayo okungaphansi kwamanzi okwenziwa ngaphakathi komthungo kanye nomthungo wangaphandle oshiselwe ipayipi lensimbi elivunguzayo (owaziwa nangokuthi yipayipi elishiselwe elivunguzayo. , ipayipi elivunguzayo, ipayipi lensimbi elivunguzayo). Ngokuqondene nezizathu ezilandelayo, isetshenziswa kabanzi ekukhiqizeni ipayipi elikhulu lensimbi:
1) ukushintsha i-engeli yomumo, ungasebenzisa ukukhiqizwa kwe-strip yobubanzi obufanayo obuhlukahlukene bensimbi yepayipi;
2) ngoba ukugoba okuqhubekayo, ubude bobude bepayipi lensimbi abunamkhawulo;
3) ukushisela ukusatshalaliswa kweyunifomu emise okuvunguzayo kumjikelezo wepayipi lonke lensimbi, usayizi wepayipi lensimbi, ukunemba okuphezulu, ukuqina okuphezulu;
4) kulula ukushintsha usayizi ofanele amanani amancane okukhiqizwa kwamapayipi ensimbi ezinhlobonhlobo eziningi.

I-Spiral weld seam ubude beshubhu eqondile, ubude beshubhu L, ubude be-weld buyi-L / cos (8). Isikhathi eside siphikisana ngepayipi lomthungo elisontekile neliqondile, ikakhulukazi, ngubani ophakeme uma kuqhathaniswa nepayipi lensimbi le-UOE. Kuvunguza ipayipi yokukhiqiza ubuchwepheshe kuze kube namuhla, kufanele sibe olunzulu futhi lesifanele ukuhlolwa kanye ukuqhathanisa, umqondo ??a weld eside Kuvunguza.

Okokuqala, ngenxa yeziphambeko ku-weld parallel, ipayipi elivunguzayo, ukukhubazeka kwe-weld kufana "nokukhubazeka kwe-oblique". Ngesikhathi sokusetshenziswa, isiqondiso sokucindezeleka esiyinhloko sepayipi yensimbi, isiqondiso se-axis yepayipi yobude obulinganayo besici siyi-samll kunepayipi lomthungo oqondile lincane; Okwesibili, njengoba insimbi yepayipi iyipuleti eligoqiwe, ukuqina komthelela we-anisotropy enkulu eduze kwenani eligingqikayo le-CVN kune-perpendicular eya lapho kuginqika khona yenani le-CVN ngokuphindwe kathathu. Ipayipi lomthungo eliqondile elihlaselwe ukucindezeleka okuyinhloko libhekene ngokunembile nesiqondiso sokumelana nomthelela wepayipi ophansi kakhulu, kuyilapho ukuvunguza kuwukunyakazisa okuphansi kakhulu lapho ibhekene nomthelela wepayipi, ukuze ukonakala kwe-spiral weld kube izinzuzo.
