Aimed at the characteristics that a continuous tube is small in diameter and large in length, the production line adopts the production mode that unwinding, straightening, corrosion resistance and coiling are continuously and synchronously carried out, and meets anti-corrosion production requirements of the single continuous tube with a large length.
Description
Technical field
The utility model belongs to continuous pipe manufacturer technical field, is specifically related to the anticorrosion production line of a kind of continuous tube outer surface 3PE.
Background technology
Continuously the pipe joint length can reach km, its external diameter between 25.4～168.2mm, by production line continuously production and be wrapped on the reel according to certain-length be delivered for use.Pipe is out of trade except doing for drilling well, well workover, sand washing, notes nitrogen, gaslift, acidifying etc. continuously, also can be used as off-shore pipeline and well site gathering line.When pipe is laid as feed-line continuously, directly open from reel, be laid on the pipe-line, because its joint length is long, has reduced site girth welding and sewed up a quantity, improved the security of pipeline, and lay quick.But, because pipe adopts the carbon steel material manufacturing continuously, be subjected to the influence of field working conditions environmental corrosion, reduced service life and the security of pipeline.The anticorrosion production line of 3PE can only carry out anticorrosion at the steel pipe of about 10 meters of joint lengths at present.Flexural deformation has taken place through twining body in pipe continuously in addition, and its caliber is little, length is long, and the anticorrosion production line of existing 3PE can't satisfy the anticorrosion production requirement of continuous pipe 3PE.
The utility model content
The technical problem that the utility model solves: a kind of continuous tube outer surface 3PE is provided anticorrosion production line, satisfies the anticorrosion production demand of pipe 3PE continuously.
The technical solution adopted in the utility model: the anticorrosion production line of a kind of continuous tube outer surface 3PE, formed by the reeler of vertically arranging successively, straightener, heating in medium frequency stove I, compressed air shotblasting machine, phosphatization pond, flushing tank, heating in medium frequency stove II, epoxy powder spray equipment, heating in medium frequency stove III, the Overmolded device of circle mould negative, shower water device for cooling, electric spark checkout gear and coiling machine.
The reel I of twining continuous pipe is housed on the described reeler, the reel II is housed on the coiling machine; By reeler will be wrapped in continuous pipe on the reel I open after uninterruptedly successively by being wrapped on the reel II behind straightener, heating in medium frequency stove I, compressed air shotblasting machine, phosphatization pond, flushing tank, heating in medium frequency stove II, epoxy powder spray equipment, heating in medium frequency stove III, the Overmolded device of circle mould negative, shower water device for cooling and the electric spark checkout gear.
The coiling speed unanimity of the uncoiling speed of described reeler, the speed that pinches of straightener and coiling machine.
The advantage that the utility model compared with prior art has and effect:
1, the flexural deformation problem has taken place at continuous pipe through twining body in the utility model, before the corrosion prevention operation, adopt straightener that continuous pipe is aligned, guaranteed the straight degree of body, thereby can guarantee the uniformity of epoxy powder spraying and the compactness of adhesive and polyethylene layer coating.
2, the long characteristics of the utility model, length little at continuous pipe caliber, adopt unreel, aligning, anticorrosion, batch the mode of production that continuous synchronization is carried out, solved the long anticorrosion production demand of continuous pipe joint length.
3, the utility model forms one deck phosphating coat by phosphating process at continuous tube outer surface before the epoxy powder spraying, to increase the adhesive force of epoxy resin layer.
