Straight seam welded pipe has simple production process, high production efficiency, low cost and rapid development. The strength of the spiral welded pipe is generally higher than that of the straight welded pipe. It is possible to produce a welded pipe with a large diameter by using a narrow blank, and it is also possible to produce a welded pipe having a different pipe diameter by using a blank of the same width. However, compared with the straight pipe of the same length, the weld length is increased by 30 to 100%, and the production speed is low. Large diameter or thick welded pipes are generally made directly from steel billets, while small welded pipe thin-wall welded pipes need only be welded directly by steel strips. Then after a simple polishing, the wire can be used. Therefore, most of the smaller diameter welded pipes are straight seam welded, and the large diameter welded pipes are mostly spiral welded. Supplement: The welded pipe is welded with strip steel, so it has no seamless pipe height in its original position. Welded pipe process Raw material unwinding - leveling - end shearing and welding - looper - forming - welding - inside and outside bead removal - pre-correction - induction heat treatment - sizing and straightening - eddy current testing - Cut off - water pressure check - pickling - final inspection (strictly check) - packaging - Liaocheng Hongfu tube industry shipments.
A Gasoline Generator is a kind of power generation
equipment, fueled by gasoline, converting other forms of energy into
electrical energy. It is driven by consisting of turbine, turbine,
Diesel Engine or other dynamic mechanical machines, turning water flow,
air current, fuel burning into mechanical energy to electricity through a
generator. It is widely used in industrial and agricultural production,
science and technology and daily lives.

Gasoline Generators feature liquid-cooled or
air-cooled engines. The air-cooled system forces air to metal fins
located around the engine cylinder. Liquid-cooled systems feature a
water pump that distributes liquid coolant to the engine. Engine heat is
transferred to the coolant, which travels to the radiator and is cooled
by air. Most modern Gas Generators feature liquid-cooled systems.
Features:
1.Quite and clean, emitting little air pollutants;
2.Reliable: stable automatic voltage regulation system and oil warning system
3. Long life and easy for maintenance
