Umumé ngandika, API 5L nuduhake API 5L pipe line, kang metu saka lemah lenga, gas, banyu, diangkut dening pipo kanggo pipo perusahaan industri lenga lan gas.

miturut proses Pabrik lan tabung Bloom digunakake manéka beda, api 5l bisa dipérang dadi api 5l pipe baja rapi lan pipe baja gandheng api, antarane jumlah panggunaan saka pipe baja gandheng luwih saka pipe baja rapi.

Line pipe bahan lan komponen kimia

API 5L bisa dipérang dadi API 5L PSL 1 lan API 5L PSL 2, kalebu API 5L PSL 1 level lan kategori: A, B, x42, x46, x52, x56, x60, x65, x70, API 5L PSL 2 level lan kategori B, x42, x46, x52, x56, x60, x65, xx70, x80.sing luwih dhuwur tingkat sifat mekanik sing kuwat.

Aplikasi: digunakake kanggo industri lenga lan gas, gas, banyu, transportasi lenga.

API SPEC 5L Line Pipe

API SPEC 5L proses produksi pipe line dipérang dadi pipe baja rapi, pipe baja ERW, submerged busur gandheng pipe.Nanging panggunaan utama pipa baja mulus (Seamless), pipa baja las tahan frekuensi tinggi jahitan lurus (Electric-Resistance Arc Welding, disingkat ERW), LSAW (Longigudinally Submerged Arc Welding short LSAW), spiral submerged arc welding pipe (Spirally). Welding Arc Submerged, cendhak SSAW) papat.

Pipa LSAW dipérang dadi UO (metode pembentuk UOE), RB (RBE), JCO (JCOE) lan jinis liyane.Steel plate ing ngecor bakal dipencet menyang U-shaped, lan banjur dipencet menyang O-, banjur nang lan njaba submerged busur welding, sawise welding, biasane ing mburi dawa kebak expander (Expanding) disebut. UOE pipe gandheng, ora ngembangaken dikenal minangka pipa UO.Pressure steel plate roll mlengkung (Roll Bending), lan banjur ing jero lan njaba welding busur submerged, sawise welding, ngembangaken pipe RBE, utawa ora ngembangaken pipe RB.Molding plate miturut jinis JOC-urutan ngembangaken pipe JCOE utawa ora ngembangaken pipe JCO sawise welding.LSAW pipo ndhuwur, nggunakake umum saka UOE.Ing frekuensi dhuwur resistance welding tabung ERW tabung embrio liwat efek kulit lan efek jarak ing dhuwur-frekuensi saiki menyang pojok nyawiji, lan banjur remet rollers ing welding meksa, kang ditondoi dening ora logam pangisi external, zona kena pengaruh panas, dhuwur efisiensi produksi.Pipa lapisan spiral SSAW kanggo pipa garis jarak adoh duwe sejarah sing dawa, pipa ing China utamane digunakake.
