ʻO ka paipu hoʻonui wela kahi ala kūikawā e hoʻonui ai i ka hoʻohana ʻana i ka hydraulic a i ʻole mechanical e koi ana i ka paipu kila mai ka pā kila ma ka radially outward dilatation molding pressure processing technology.Mechanical 'ano ma mua o hydraulic hana, mea hana, maʻalahi a oi ka mana i loko o ke ao nei alakaʻi pono'ī-nui nui-caliber seam welded paipu hoʻonui kaʻina kaʻina mana koho.

ʻO ke ʻano hana o ka paipu hoʻonui wela, ʻo ia ka paipu anawaena liʻiliʻi e hana ana i kahi paipu anawaena nui.Thermal hoonui paipu wela-'ōwili kila mechanical waiwai ma mua o ka mea emi.Limited i ka maʻamau kila seamless kila paipu i kaupalena 'ia, e like me ka hope-mea kūʻai mai koi thermal hoʻonui paipu no laila ua hanau, thermal hoʻonui paipu arbitrary maʻamau kükohu mea 'ano nui, maʻamau ma muli o ka mea kūʻai mai pono a me manufacturing, thermal hoʻonui paipu mea, mākou. 'Ōlelo pinepine i ka hoʻonui wela o ka paipu, he haʻahaʻa ka haʻahaʻa, akā e hoʻopōkole i kahi paipu kila ikaika, (seamless steel pipe) hiki ke kuhikuhi ʻia e like me ka hoʻonui ʻana.
