Pipa Baja SSAW Spiral Las x42
Pipa Baja SSAW Spiral Las x42
Fitur
-
Pipa sing dilas spiral digawe kanthi nggulung strip baja saka baja struktural karbon rendah utawa baja struktural paduan rendah menyang pipa kosong miturut sudut heliks tartamtu (sing diarani sudut pembentuk), banjur ngelas sambungan pipa. Pipa iki bisa ngasilake pipa baja diameter gedhe saka strip baja sing sempit.

(1) Pipa baja kanthi diameter sing beda-beda bisa diprodhuksi kanthi nggunakake baja strip kanthi jembar sing padha, utamane pipa baja kanthi diameter gedhe bisa diprodhuksi kanthi baja strip sing sempit.
(2) Ing kahanan tekanan sing padha, tegangan las spiral luwih cilik tinimbang las lurus, yaiku 75% ~ 90% saka pipa las lurus, saengga bisa nahan tekanan sing luwih gedhe. Dibandhingake karo pipa las lurus kanthi diameter njaba sing padha, kekandelan tembok bisa dikurangi 10% ~ 25% ing tekanan sing padha.
(3) Dimensine akurat, umume toleransi diameter kurang saka 0,12%, defleksi kurang saka 1/2000, lan ovalitas kurang saka 1%, mula prosedur ukuran lan pelurusan umume bisa diilangi.
(4) Produksi terus-terusan bisa ditindakake. Sacara téori, pipa baja sing dawane tanpa wates bisa diprodhuksi. Mundhut endhas lan buntut pemotongan cilik, lan tingkat panggunaan logam bisa ditambah nganti 6% ~ 8%. (5) Dibandhingake karo pipa las lurus, fleksibel ing operasi, lan trep kanggo ngganti varietas lan nyetel.
(6) Piranti sing entheng lan investasi awal sing luwih sithik. Bisa digawe dadi unit mobile jinis trailer kanggo langsung ngasilake pipa sing dilas ing lokasi konstruksi ing ngendi pipa dipasang.
(7) Gampang banget kanggo nglakokake mekanisasi lan otomatisasi.
Pipa las spiral utamane digunakake ing teknik banyu ledeng, industri petrokimia, industri kimia, industri tenaga listrik, irigasi pertanian lan konstruksi kutha ing China. Digunakake kanggo transportasi cair: pasokan banyu lan drainase. Kanggo transportasi gas: gas batu bara, uap lan gas minyak bumi cair. Digunakake minangka struktur: digunakake minangka pipa penggerak tiang pancang lan jembatan; Pipa kanggo dermaga, dalan lan struktur bangunan, lan liya-liyane.
