Three clamps of oil recovery well head side or little cross of four clamps

Three clamps of oil recovery well head side or little cross of four clamps belongs to the machinery that recovers the oil, each welding of leading to in the photogenic interconnection of three lateral surface of forging square cross main part is adorned one admittedly and is forged the clamp nipple joint, forges the solid dress of internal thread nipple joint welding on a fourth lateral surface of forging square cross main part for one, and communicates each other, threely forges clamp nipple joint axial lead and one and forges internal thread nipple joint axial lead and be located the coplanar, or adorn one admittedly in each welding that four photogenic interconnection of lateral surface of forging square cross main part are led to and forge the clamp nipple joint, forge clamp nipple joint axial lead for four and be located the coplanar, this little cross adopts forges part welding integrated configuration, have rational in infrastructure, the yield is high, of high quality, the bearing capacity strong, lon
