Description
Technical field
The utility model relates to pipe technology field, is specially the square winding of a kind of high density polyethylene (HDPE) (HDPE) and strengthens carat pipe.
Background technique
Along with the increase of urban population number, in the designing requirement medium caliber of buried pipeline in continuous increasing, simultaneously along with the increasing of bore, also need the larger buried degree of depth, the ring stiffness index that these conditions all require tubing to possess more to increase, prevents from occurring the phenomenons such as conquassation in using process.
And present tubing, most hollow wound pipe technology that adopts, is namely wound with reinforcement pipeline on tubing.And the end face majority strengthening pipeline is arc shaped surface.But the top of this arc shaped surface is easily subject to excessive pressure and causes damaging, and finally makes the ring stiffness of whole pipeline lower.And if the arc of employing said structure strengthens install pipeline stiffening rib, stiffening rib is difficult to processing, and adopt in the middle of two pipelines and arrange stiffening rib, stiffening rib is difficult to be combined closely with the outer wall of pipeline, easily occurs blind spot, affects ring stiffness.
Summary of the invention
The technical problem that the utility model solves is to provide the square winding of a kind of high density polyethylene (HDPE) to strengthen carat pipe, to solve the problem in above-mentioned background technology.
The technical problem that the utility model solves realizes by the following technical solutions:
The square winding of a kind of high density polyethylene (HDPE) strengthens carat pipe, comprise body, on described body, spiral winding has square pipe, described square pipe has two, parallel setting, and utilize melting flat rubber belting to carry out welding between the tube wall of described two square pipes, weld is formed and strengthens muscle, described enhancing muscle is erected between described two square pipes, with the outer wall vertical of described body, and end face flushes with the end face of described square pipe, the thickness of described enhancing muscle is 1.2-2 times of described square pipe pipe thickness.
Improve as one, described enhancing muscle is high density polyethylene (HDPE) melting flat rubber belting.High density polyethylene (HDPE) (High Density Polyethylene, referred to as " HDPE ") is high, the nonpolar thermoplastic resin of a kind of degree of crystallinity.HDPE is high, the nonpolar thermoplastic resin of a kind of degree of crystallinity.High density polyethylene (HDPE) is white particle that is nontoxic, tasteless, odorless, and fusing point is about 130 DEG C, and relative density is 0.941 ~ 0.960.It has good heat resistance and winter hardiness, and chemical stability is good, also has higher rigidity and toughness, and mechanical strength is good.Fire retardant, environmental stress crack resistance is also better.Melting point 120 ~ 160 DEG C.For the material that molecule is larger, suggestion melting point scope is between 200 ~ 250 DEG C.High density polyethylene (HDPE) is kind of a white powder granular product, and nontoxic, tasteless, density is at 0.940 ~ 0.976 g/cm
3in scope; Degree of crystallinity is 80% ~ 90%, and softening point is 125 ~ 135 DEG C, and serviceability temperature can reach 100 DEG C; Hardness, tensile strength and creep properties are better than Low Density Polyethylene.
Improve as one, the thickness of described enhancing muscle is 1.5 times of described square pipe pipe thickness.Inventor finds in practice, and adopt square pipe, the sidewall due to square pipe is smooth, is very easy to be combined closely with enhancing muscle.And if it is excessive to strengthen muscle thickness, easily there is blind spot, cause ring stiffness to reduce, if it is too small to strengthen muscle thickness, then can affects the adhesive strength of two square pipes, reduce ring stiffness equally.Finally, inventor finds, when adopt strengthen the thickness of muscle be the 1.2-2 of described square pipe pipe thickness doubly, especially 1.5 times time, overall ring stiffness can be strengthened to greatest extent.
The utility model use high density polyethylene (HDPE) melting flat rubber belting material mouth mould surface temperature be designed to 185 degree, flat rubber belting true temperature by infrared temperature detect 180.5 degree.High density polyethylene (HDPE) melting flat rubber belting temperature is 180.5 degree, square pipe sidewall is wound around closely and bonds together, and strengthens muscle in being formed.And the outer wall of body is circular arc, is easy to and strengthens muscle and be combined.
Owing to adopting above technological scheme, the beneficial effects of the utility model are as follows:
Strengthen muscle lower contact tube body wall, top connects square pipe and flushes, strengthen muscle both sides contact welding square tube, structure is rendered as " setting " shape, enhancing muscle in the utility model is erected at the centre of two square pipes, and strengthening muscle thickness increases, and intensity improves, the outer surface of body is convex roundlet arcuation, firmly welding square pipe.Most of power that the external world is pressed in the tube wall of body is then born by the enhancing strength in square tube, does not place the local pressure be subject to of the tube wall strengthening muscle then very little, under the prerequisite of equivalents weight, the performance of product (ring stiffness) is got a promotion.
