ERW (Electric Resistance Welding) paipu kilaua kapa ʻia ʻo ERW paipu a i ʻole HF welded pipe, he nui nā pono e like me kēia:

1) kiʻekiʻe hana hana pono, haʻahaʻa kumu kūʻai, kona kumu kūʻai e pili ana i ka UOE hili pololei submerged arc welded kila, 85%;

2) kiʻekiʻe dimensional pololei, kona poepoe (Roundenss) oi ma mua o spiral welded paipu, ka counterpart hiki ke hoola i ka nui o na hora ma ke kula;

3) ʻili maʻemaʻe, hiʻohiʻona nani, kahi kūpono i ka uhi ʻana o loko a me waho.I ka wā ma mua, ilihune hilinaʻi o ERW paipu welds, paipu ma laila ua nui ka helu o nā ulia, pela kaupalena ka hoʻohana 'ana i ka ERW paipu.I kēia mau lā, ua hoʻolilo nui ʻo Zhejiang Jinzhou Group, ma o ka hui pū ʻana o nā mea noiʻi a me ka mea hana paipu, ua loli nui kēia kūlana o ka maikaʻi o ka maikaʻi weld paipu kila ERW hiki ke hoʻohālikelike ʻia me ka LSAW like.

ʻO ke kaʻina hana o ka paipu ERW e lawe i kēia mau hana:

1) hoʻomalu i ka hoʻokomo wela i ke kaʻina hana, nui nā mea e pili ana i ka hoʻokomo wela, ʻo ka mea mua ka convergence angle (Convergency Angle).Ua hōʻike nā hualoaʻa, i ka hihia o nā kumu ʻē aʻe mau, ʻoi aku ka nui o ka huina convergence i mea e hoʻoulu ai i ke anuanu, ʻoi aku ka liʻiliʻi o ka huina convergence e hopena i ke ahi.ʻO kekahi kumu e pili ana i ka paipu hoʻokomo wela i ka wikiwiki o ka laina hana.Hōʻike nā hualoaʻa i ka hihia o nā kumu ʻē aʻe mau, ʻoi aku ka wikiwiki o ka wikiwiki hiki ke kumu i ka wili anu, lohi, hiki ke alakaʻi i ke ahi.

2) hoʻomaikaʻi i ka laina ʻenehana ʻike ʻana i ka paipu ma Jinzhou, i mea e hōʻoia ai i ka maikaʻi o ka paipu ERW, ʻoi aku ka nui o ka ʻike kīnā ʻole i ka ʻenehana paipu.Unwinding strip ma nā ʻaoʻao ʻelua o ka hoʻāʻo ultrasonic, eddy i kēia manawa ke nānā ʻana ma hope o ka pau ʻana o ka wili.Eia kekahi, he helu o ka nānā ʻana, a me ka laʻana no ka hoʻāʻo palahalaha a me nā hoʻāʻo ʻenehana ʻē aʻe.
