Corrosion-resistant metallurgical composite bimetal longitudinal submerged-arc welded steel pipe and method for manufacturing same

The invention provides a corrosion-resistant composite bimetal longitudinal submerged-arc welded steel pipe and a method for manufacturing the same. The method includes steps of (1), manufacturing bimetal composite steel plates by a hot rolling process; (2), carrying out edge milling, pre-bending, JCO forming and pre-welding on the bimetal composite steel plates manufactured in the step (1); (3), welding weld joints of a steel pipe by a submerged-arc welding process, particularly, welding a carbon steel layer of a base layer at first when the weld joints are welded, and then welding metal of a clad layer of a corrosion-resistant layer. The steel pipe is obtained after JCO forming and pre-welding are carried out on the bimetal composite steel plates. The corrosion-resistant composite bimetal longitudinal submerged-arc welded steel pipe and the method have the advantages that the corrosion-resistant metallurgical composite bimetal longitudinal submerged-arc welded steel pipe is manufactured by a hot rolling metallurgical composite bimetal steel plate and JCOE pipe manufacturing process and the efficient automatic submerged-arc welding process, double layers of metal of the steel pipe can be metallurgically combined with each other, and accordingly the steel pipe is high in strength, integrity and corrosion resistance; the JCOE pipe manufacturing process is adopted, so that the steel pipe is high in mechanical degree, production efficiency and overall dimensional accuracy, and steel pipes with the lengths of 12 meters can be produced by the method.

Device for cutting hair, floor drain with device and working method of device

The invention discloses a device for cutting hair, a floor drain with the device and a working method of the device. The device comprises a shell, a hydroelectric generator, a circuit board, a rotating motor and a blade shell, wherein water through holes are formed in the shell; the hydroelectric generator is mounted on the shell and is provided with blades; the circuit board is mounted on the shell and is electrically connected with the hydroelectric generator; the rotating motor is mounted on the shell and is electrically connected with the circuit board; a blade component with a plurality of blades is assembled on the shell and in transmission connection with the rotating motor; and the rotating motor is rotated to drive the blade component to move leftwards and rightwards to cut hair which flows in from the water through holes. The device has the advantages that when articles such as hair flow into the device from the water through holes, the hair is cut into small fragments through a shearing effect of the blades and edges of the water through holes and is carried away by water flow, then the hair is not wound around different components, and the floor drain is not blocked. In addition, due to adoption of the hydroelectric generator, power can be generated with water flow, steps of external power supply connection or foot stamping are avoided, and thus the device is simple and energy-saving.

Glass fiber-reinforced plastic high-strength composite strengthening rib and production technology thereof

The invention discloses a glass fiber-reinforced plastic high-strength composite strengthening rib and a production technology thereof. The glass fiber-reinforced plastic high-strength composite strengthening rib comprises glass fibers. The glass fibers are winded with each other to form a staggered structure. The glass fibers are uniformly immersed through a resin adhesive. The resin adhesive is prepared from 0.1-0.5 parts by weight of unsaturated polyester resin, 0.005-0.02 parts by weight of a curing agent and 0.005-0.02 parts by weight of a promoter by mixing. The glass fiber-reinforced plastic high-strength composite strengthening rib and a resin base material are prepared from the same material and the glass fiber-reinforced plastic high-strength composite strengthening rib and the resin base material are fused at a high temperature under high pressure so that glass fiber-reinforced plastic well cover integrity is good. The glass fiber-reinforced plastic high-strength composite strengthening rib has good toughness and a high bending amount, produces deformation under high pressure and can be recovered after pressure release. The glass fiber-reinforced plastic high-strength composite strengthening rib is prepared from a non-metal and has no recovery and use value so that well cover pilferage is thoroughly prevented.
