He aha ka ʻokoʻa ma waena o ka paipu kila seamless a me ka paipu kila welded?
I kēia manawa, ua hoʻokaʻawale ʻia nā paipu kila i hoʻohana ʻia i ko mākou ola i kēlā me kēia lā i ʻelua mau ʻano: welded steel pipes a me seamless steel pipes.Hiki ke ʻike ʻia ka ʻokoʻa ma waena o kēia mau paipu kila mai ʻekolu mau ʻano:
1. I ka nana aku, o ka like ole ma waena o ka paipu kila seamless a me ka paipu kila welded i ka paia o loko o ka paipu welded i wili iwi iwi aoao, oiai ka seamless kila paipu.
2. He kiʻekiʻe ke kaomi o ka paipu seamless, a ʻo ka paipu welded ma kahi o 10MPa.I kēia manawa ʻaʻole maʻemaʻe ka paipu welded.
3. Hoʻokumuʻia ka paipu kila maʻemaʻe i ka manawa hoʻokahi i ka wā o ka'ōwili.Pono e wili ʻia nā paipu kila welded, a hoʻohana mau ʻia ka wiliwili spiral a me ka wili pololei.ʻOi aku ka maikaʻi o nā paipu seamless a ʻoi aku ke kumu kūʻai.
