(1) pipa baja kalayan diaméter béda bisa dihasilkeun ku ngagunakeun baja strip kalayan rubak sarua, utamana pipa baja kalayan diaméter badag bisa dihasilkeun ku baja strip sempit.
(2) Dina kaayaan tekanan anu sami, tegangan las spiral langkung alit tibatan las lempeng, nyaéta 75% ~ 90% tina pipa anu dilas lempeng, ku kituna tiasa nanggung tekanan anu langkung ageung.Dibandingkeun sareng pipa dilas lempeng kalayan diaméter luar anu sami, ketebalan témbok tiasa dikirangan ku 10% ~ 25% dina tekanan anu sami.
(3) Diménsi anu akurat, umumna kasabaran diaméterna kirang ti 0,12%, deflection nyaeta kirang ti 1/2000, sarta ovality nyaeta kirang ti 1%, jadi prosedur sizing na straightening bisa umum disingkahkeun.
(4) Produksi kontinyu mungkin.Dina tiori, pipa baja infinitely panjang bisa dihasilkeun.Leungitna motong sirah jeung buntut leutik, sarta laju utilization logam bisa ngaronjat ku 6% ~ 8%.(5) Dibandingkeun jeung pipa dilas lempeng, éta fléksibel dina operasi, sarta merenah dina ngarobah variétas sarta nyaluyukeun.
(6) Beurat hampang pakakas sareng kirang investasi awal.Ieu bisa dijieun kana unit mobile trailer-tipe pikeun langsung ngahasilkeun pipa dilas dina situs konstruksi dimana pipelines diteundeun.
(7) Ieu gampang pikeun ngawujudkeun mechanization na automation.
Spiral dilas pipe utamana dipaké dina rékayasa cai ketok, industri pétrokimia, industri kimia, industri kakuatan listrik, irigasi tatanén jeung konstruksi urban di Cina.Dipaké pikeun transportasi cair: suplai cai jeung drainase.Pikeun transportasi gas: gas batubara, uap sareng gas minyak bumi cair.Dipaké salaku struktur: dipaké salaku tihang nyetir pipe na sasak;Pipa pikeun darmaga, jalan jeung wangunan wangunan, jsb.
Aplikasi
Salaku Cina industri bahan logam ngarah usaha, perdagangan baja nasional jeung logistik "Saratus perusahaan iman alus", Cina usaha dagang baja, "Top 100 usaha swasta di Shanghai". Shanghai Zhanzhi industri Grup Co., Ltd., (singketan ka Zhanzhi Grup). ) nyokot "Integritas, Practicality, Inovasi, Win-Win" salaku hiji-hijina prinsip operasi na, salawasna persist dina putting paménta konsumén di tempat munggaran.
