L360 pipa baja pangolahan khusus pipa transportasi pipa
L360 Pipeline Steel, Tujuan: API SPEC 5L-2011 (Pipeline Specification), dikembangake lan diterbitake dening American Petroleum Institute, digunakake ing saindenging jagad.Pipepipe: Kanggo ngeterake lenga, gas utawa banyu saka lemah liwat pipa menyang industri minyak lan gas.Pipeline pipe kalebu rapi lan gandheng pipe rong jinis, mburi pipe wis flat mburi, Utas mburi lan soket mburi;Mode sambungan yaiku welding pungkasan, sambungan hoop, sambungan soket lan liya-liyane.Bahan utama tabung yaiku B, X42, X46, X56, X65, X70 lan bahan baja liyane.Perusahaan kita lulus sertifikasi API (API 5CT lan API 5L) ing Agustus 2009.
L360 Pipeline Steel, API SPEC 5L GB/T9711.1 GB/T9711.2 Aplikasi Standar Nasional China: Pipa pangiriman oksigen, banyu lan minyak ing industri minyak lan gas alam B, X42, X52, X60, X65, X70 L245 L290 L320 L360 L390 L450 L485
Kanthi pangembangan teknologi pipo baja piring lan kemajuan pipe gandheng mbentuk, teknologi welding, sawetara aplikasi saka pipe karo pipe gandheng ing mboko sithik ngembangaken, utamané ing diameteripun gedhe gandheng orane katrangan pipe kelas kaluwihan liyane nyoto, lan faktor biaya, pipe gandheng wis dominan ing lapangan pipe line, kang matesi pangembangan stainless steel pipe line rapi baja.Ing taun 2004, output pipa rapi kira-kira 400.000 t, kelas baja kalebu X42-70, lan varietas yaiku pipa darat lan pipa kapal selam.
Produksi pipa pipo bahan baja dhuwur nganggo proses perawatan pemanasan microalloying, biaya produksi pipa mulus stainless steel temenan luwih dhuwur tinimbang pipa sing dilas, lan kanthi perbaikan kelas baja, kayata X80 lan ndhuwur watesan pipa pipa baja sing padha karo karbon. , proses conventional pipe rapi angel kanggo ketemu syarat kedhaftar;Saben pabrikan pipa alloy 12Cr1moV nindakake karya riset ilmiah kanggo nambah resistensi korosi pipa pipa lan kinerja stabil ing lingkungan suhu rendah lan dhuwur.
