(Total 12 Products for Hot Welding Steel Bend Pipes)
Production process Welding elbow production process, if the long radius of the elbow, you must first select specifications, put forward the tube material. Spread ratio, through theoretical calculation, the general expansion rate of 35% - 33%, and push back. Short radius 219mm general expanding diameter rate of 50%....
The elbow made by cold extrusion technology of internal and external mold is beautiful, uniform wall thickness and small size, so it is used for stainless steel elbow, especially for stainless steel elbow. The precision of internal and external die used in this process is high, and the requirement for the wall...
Products have special requirements are still in use. The stamping of the elbow is formed by using the tube blank equal to the outside diameter of the elbow.Before stamping, the tube blank is placed on the lower die, and the inner core and the end mould are filled in the tube blank, and the upper die downward movement...
Stamping welding elbow, it is the same material with the tube sheet metal stamping die with a half block ring bend, and then the two half ring elbow for welding. Because of various pipe welding standards are different, usually by the group on the fixed semi-finished products of the factory, on-site construction...
Spiral steel large diameter welding pipes
Spiral mainly used in water engineering, petrochemical industry, chemical industry, power industry, agricultural irrigation, urban construction, it is one of 20 key product of development. For the transport of liquids: water supply, drainage, sewage treatment works, lose mud, sea water. Used for gas transportation:...
Spirally carbon welded steel pipe
Spiral pipe itself does not get hot, but the experimental samples will be significant fever. When the heating temperature exceeds the arc melting machine, radio frequency sensors will provide more control, so that scientists can adjust the alloy of specific composition ratio. Spiral Strong pressure steel, plastic, and...
Straight welded longitudinal steel welding pipe
According to use points for general welded pipe, galvanized pipe, oxygen blowing pipe, wire casing, metric pipe, roller tube, deep well pump, automobile with pipe, transformer tube, welded thin-wall pipe, welding shaped tube and spiral welded pipe.And according to weld shape classification can be divided into straight...
Saw welding straight round pipes
Single or multiple (2 to 5) electrode wire variations of the process exist. SAW strip-cladding utilizes a flat strip electrode (e.g. 60 mm wide x 0.5 mm thick). DC or AC power can be used, and combinations of DC and AC are common on multiple electrode systems. Constant voltage welding power supplies are most commonly...
Welding elbow is shrimp "turn", it can be in the pipe or plate cutting after welding and become, and its specifications can be large. The number of nodes and the bending radius are determined by the producer. Welding bending is not very smooth, both of the bending radius is not large, generally about 1 times the...
Branch connection fittings of steel
The utility has a new addition to the traditional role of the tee, but also play the role of duplex valve that executives and branch output can select any one closed, the other for the smooth working condition; the utility model can also be arbitrary adjusting executives and branch pipe output flow ratio, as long as...
Spiral pipe Also known as spiral steel pipe and spiral welded pipe spiral pipe is low carbon structural steel or low alloy structural steel strips by a helix angle (called forming angle) rolled into a tube, then the tube seam welded together made, it can be with a narrow strip steel production of large diameter steel...
Spiral welded carbon steel pipe
Also known as helical or spiral tube body. Spiral tube outer diameter of about 30 nm and an inner diameter of about 10 nanometers, adjacent helical pitch of about 11 nm. 1 week of each spiral from 6 surrounded nucleosome, H1 histone in the spiral cavity of the inner surface of maintenance of spiral structure plays an...
