Haina Specializes in Customized Welded Pipe and Seamless Pipe Equipment
All of our products, including ERW Pipe Mills, Spiral Pipe Mills, Seamless Pipe Mills and Finishing Equipment, are manufactured in strict accordance with the standards in our ISO registered factory.
API grade ERW pipe mill is mainly used for producing the high-grade pipe such as oil and gas delivering and casing pipe in the oil well. These high-grade pipes strictly require the pipe material and pipe quality. The API grade ERW pipe mill has IF annealing, air cooling roller, UT detector, high pressure hydrotester and other detect equipment.
LSAW pipe mill has special advantages in the mill. Compared with ERW, the quality and energy consumption of straight seam submerged-arc pipe is easier to be controlled, and is welded better and low consumption.
The steel coils are unfolded and leveled by the mill equipment. And they are sent to the forming machine in a certain angle. Supplemented by a certain angle, the continual pipes are formed in the principle of three-roll rolling machine. Continual spiral welding is welded by submerged-arc welding machine. When the uncoiling, coil detaching, leveling, steel cutting and welding are working, the host machine needs to stop and wait.
SSAW Pipe Mill
Precision stainless steel welded pipe mill adopts precise forming machine. It processes the steel sheet to the pipe. After welding, welding seam internal grinding, industrial black rust annealing, the industrial stainless welded pipe is produced. The welding seam of this pipe is very strong, no matter bending or flatten. It will not have the crack.
Stainless Steel Pipe Mill
The seamless pipe making machine of our company uses the world's advanced technology to produce qualified hot-rolled seamless steel tubes. Main uses: petroleum casing, high-pressure fluid delivery pipe, boiler pipe, structural pipe and machining pipe, etc.
Seamless Pipe Mill
The bimetallic composite pipe is composed of two different metal materials, and the tube layers are tightly combined through various deformations and connection technologies, so that the two materials are integrated into a new type of metal composite pipe.
Bimetallic Composite Pipe Mill
The slitting line is used to open the thin coil and slit the steel with the circle shear. By the precise tensioner, the accurate tension is supplied. The recoiler takes the process. Then, the narrow coils are packed.
Slitting Line
Heavy cut to length line is to open the coil, level the steel, size the steel and cut to length according to the setting length. Due to the thick steel, the line adopts heavy hydraulic cutter and powerful leveling. If the thickness has large difference, the line will adopt two sets of powerful leveling.
Cut to Length Line
