Apa sing diarani Pipa Seamless Baja Tahan Karat
Pipa seamless baja tahan karat iku bahan baja dawa kanthi bagean bolong lan ora ana sambungan ing sakubenge. Sing luwih kandel kekandelan tembok produk, luwih ekonomis lan praktis. Sing luwih tipis kekandelan tembok, biaya pangolahan bakal mundhak kanthi signifikan.
Proses prodhuk iki nemtokake kinerjane sing winates. Umumé, pipa baja tanpa sambungan nduweni presisi sing kurang: kekandelan tembok sing ora rata, padhange permukaan njero lan njaba pipa sing kurang, biaya ukuran sing larang, lan bintik-bintik bolong lan ireng ing permukaan njero lan njaba sing angel dicopot; deteksi lan Pembentukan kudu diproses kanthi offline. Mulane, pipa iki nuduhake kaunggulane ing babagan tekanan dhuwur, kekuatan dhuwur, lan bahan struktural mekanik.
