PROCESS LINE OF TUBE ELECTRIC WELDING PLANT Russian patent published in 2013 - IPC B21C37/08 

FIELD: process engineering.

SUBSTANCE: proposed line comprises forming and sizing-profiling mills mounted on foundation plates and supports, tube welding machine, horizontal stands with four bearing vertical elements and covers, and vertical stands. Some of vertical stands have vertical bearing elements. Other vertical stands have support elements. Working line comprises also lubing and cooling system with working tank and filter, settling tank, welded tube cooler, lubricant-coolant collection troughs, and flaw detector. Note here that foundation plates are composed of posts with ledges parallel with plant axis to for support frames to rest thereon. Said frames are composed of horizontal I-beams with bosses welded thereto. Lower ends of bearing vertical elements of horizontal and vertical stands are secured in vertical cylindrical bores on said bosses and I-beam wall. Upper ends of bearing vertical elements of horizontal and vertical stands are rigidly jointed together by covers and threaded joints. Lower ends of bearing vertical elements of horizontal are rigidly interconnected and connected with I-beam elements by inner and outer tie plates. Note here that vertical elements or horizontal stand outer tie plates made thrust elements for vertical stands.

EFFECT: lower production costs.
