Ringkesan pipa baja paduan

Pipa Baja Paduan digunakake ing aplikasi sing mbutuhake sifat tahan korosi moderat kanthi daya tahan sing apik lan kanthi biaya ekonomis. Sederhanane, pipa paduan luwih disenengi ing wilayah sing pipa baja karbon bisa rusak. Ana rong kelas baja paduan - paduan dhuwur lan baja paduan rendah. Pipa sing kalebu baja paduan rendah duwe kandungan paduan sing kisarane kurang saka 5%. Dene kandungan paduan baja paduan dhuwur bakal kisarane antarane 5% nganti udakara 50%. Kaya umume paduan, kemampuan tekanan kerja Pipa Seamless Baja Paduan udakara 20% luwih dhuwur tinimbang pipa sing dilas. Dadi ing aplikasi sing duwe tekanan kerja sing luwih dhuwur minangka prasyarat, panggunaan pipa seamless dibenarkan. Sanajan luwih kuwat tinimbang pipa sing dilas, biayane luwih dhuwur. Salajengipun, risiko korosi intergranular ing zona las sing kena pengaruh panas luwih akeh ing produk sing dilas. Bentenane sing katon antarane Pipa Las Baja Paduan lan produk seamless yaiku jahitan latitudinal ing sadawane pipa. Nanging, saiki, kanthi kemajuan teknologi, sambungan sing ana ing Pipa ERW Baja Paduan bisa dikurangi kanthi signifikan liwat perawatan permukaan, saengga tetep ora katon dening mripat manungsa.
