Abstract
The invention discloses a manufacturing method for a short-pitch external thickened oil pipe with upset pipe ends. The manufacturing method comprises the following steps of upsetting two ends of a long oil pipe; sawing the long oil pipe into two segments, welding two upset parts, upsetting one of the sawing ends, and cutting a welded junction open to manufacture a steel pipe with required specification. According to the manufacturing method, production of the short-pitch external thickened oil pipe is ensured by two-step upsetting and welding technologies; mass production of the short-pitch external thickened oil pipe is effectively solved; more economic benefits are brought for enterprises; normal production of thickening equipment and thermal treatment equipment is ensured.
Description
Technical field
The present invention relates to external upset tubing and make field, particularly relate to a kind of preparation method of pipe nipple external upset tubing of tube upset.
Background technology
At present, thicken equipment requirement external upset tubing length at least 6m, length is that the pipe nipple external upset tubing of below the 6m of 1.5m, 3m, 4.5m cannot be produced.
Summary of the invention
The technical problem to be solved in the present invention is to provide a kind of preparation method of pipe nipple external upset tubing of tube upset, in order to produce the pipe nipple external upset tubing of below 6m.
For reaching above-mentioned purpose, the preparation method of the pipe nipple external upset tubing of a kind of tube upset of the present invention, comprises the following steps:
(1) by thick for a long oil pipe two ends pier;
(2) sawing of described long oil pipe is become two sections, by two pier thick position welding, a sawing end pier is thick, weld bond is cut can obtain required specification steel pipe afterwards.
The thick span access location length of wherein said pier is more than 150mm.
The invention difference from existing technology is that the present invention achieves following technique effect:
The present invention ensures the production of pipe nipple external upset tubing by employing twice jumping-up and solder technology, efficiently solves the batch production of the thick oil pipe of pipe nipple pier, for enterprise brings more economic benefits, ensure that the normal production of thickening equipment and Equipment for Heating Processing.
Below in conjunction with accompanying drawing, the invention will be further described.
Accompanying drawing explanation
Fig. 1 is the structural representation of the manufacturing process of the pipe nipple external upset tubing of tube upset of the present invention.
Description of reference numerals: 1-weld bond.
Detailed description of the invention
Below in conjunction with embodiment, to above-mentioned being described in more detail with other technical characteristic and advantage of the present invention.
As shown in Figure 1, adopt the oil pipe of 3 specification 114.3mm*6.88mm, length 9m before jumping-up, make the pipe nipple heavy wall tubing that length is 1.5m, 3m, 4.5m respectively.
First two ends upset end length is extended to 150mm from 110mm by twice jumping-up molding mode by the oil pipe of 3 9m, then be cut into 3 length with band saw and be respectively 1.58m, 3.08m, the pipe nipple that 4.58m thickeies with one end (considers that in upsetting process, length reduces 80mm, pipe nipple length increases 80mm), adopt the mode of welding, respectively the upset end of the pipe nipple upset end cut and other is welded together, jumping-up is carried out to the other end, after treating other end jumping-up, then cut from commissure, produce 1.5m respectively, 3m, the pipe nipple external upset tubing of 4.5m, efficiently solve the production of pipe nipple external upset tubing.
Above-described embodiment is only be described the preferred embodiment of the present invention; not scope of the present invention is limited; under not departing from the present invention and designing the prerequisite of spirit; the various distortion that those of ordinary skill in the art make technical scheme of the present invention and improvement, all should fall in protection domain that claims of the present invention determines.
Claims (2)
