Full butt joint tank heater and production method thereof
Technical field:
The present invention relates to a kind of tank heater and production method thereof.
Background technology:
Existing tank heater is formed by connecting some groups of heaters, and every group of heater all comprises assembles pipe (standpipe) and horizontal heating calancria, and each is organized between the heater and connects with tube connector.Shortcoming is that the connected mode of heating calancria and tube connector and assembly pipe is to assemble the pipe upper shed; With welding in heating calancria or the tube connector insertion opening; Can't detect with x-ray inspection for this angle welding, make the product that has hidden danger be mounted for producing, be prone to during use leak.
Summary of the invention:
Technical problem to be solved by this invention provides a kind of can the detection with x-ray inspection, and product quality can be guaranteed, and is difficult for taking place the full butt joint tank heater and the production method thereof of leakage during use.
Above-mentioned purpose is achieved in that it is formed by connecting some groups of heaters; Every group of heater all comprises assembles pipe and horizontal heating calancria; Each is organized between the heater and connects with tube connector; The junction of assembly Guan Zaiyu heating calancria of the present invention and tube connector all is provided with pipe joint, and making the weld seam of assembling pipe and heating calancria and tube connector junction all is butt weld.
Can also establish threeway in the lower end of assembling pipe, threeway is connected with end tube connector with end heating calancria.
Production method of the present invention is: adopt the method for casting to produce and assemble pipe, all be cast with pipe joint in the junction of assembling pipe and heating calancria and tube connector during casting, the pipe joint of the assembly pipe that the utilization casting is good then and heating calancria and tube connector carry out butt welding;
Can also be when pipe is assembled in casting in the lower end of assembling pipe casting three-way simultaneously, 180 ° of mouths on threeway both sides are carried out butt welding with end heating calancria and end tube connector respectively.
Also can utilize the breeches pipe machine that ejects to eject pipe joint assembling the junction of pipe with heating calancria and tube connector, the pipe joint that ejects of utilization and heating calancria and tube connector carry out butt welding then.
Advantage of the present invention is: owing to assemble the weld seam of pipe and heating calancria and tube connector junction all is butt weld, and institute can be guaranteed product quality, difficult leakage during use so that detect with x-ray inspection.
Description of drawings:
Accompanying drawing is the structural representation of one group of heater of the present invention.
The specific embodiment:
With reference to accompanying drawing; It is formed by connecting some groups of heaters; Every group of heater all comprises assembles pipe 1 and horizontal heating calancria 2, and each is organized between the heater and connects with tube connector, at first assembles pipe with No. 35 steel castings during production; Junction assembling pipe and heating calancria and tube connector is cast with pipe joint 3, and making the weld seam of assembling pipe and heating calancria and tube connector junction all is butt weld.
Can be cast with threeway 4 simultaneously in the lower end of assembling pipe during casting, threeway is connected with end tube connector with end heating calancria 5.
Production method is: adopt the method for casting to produce and assemble pipe, all be cast with pipe joint in the junction of assembling pipe and heating calancria and tube connector during casting, the pipe joint of the assembly pipe that the utilization casting is good then and heating calancria and tube connector carry out butt welding;
Can also be when pipe is assembled in casting in the lower end of assembling pipe casting three-way simultaneously, 180 ° of mouths on threeway both sides are carried out butt welding with end heating calancria and end tube connector respectively.
Also can utilize the breeches pipe machine that ejects to eject pipe joint assembling the junction of pipe with heating calancria and tube connector, the pipe joint that ejects of utilization and heating calancria and tube connector carry out butt welding then.
