Abstract

The invention discloses a minor-caliber fiber reinforced plastic sand inclusion pipe. From inside to outside, the minor-caliber fiber reinforced plastic sand inclusion pipe comprises an inner lining layer contacting a fluid medium, an internal enhancement layer, a sand inclusion layer and an external enhancement layer, wherein the internal enhancement layer is an internal enwinding layer; and the external enhancement layer comprises an external surface protection layer and an external enwinding layer between the sand inclusion layer and the external surface protection layer. The minor-caliber fiber reinforced plastic sand inclusion pipe is characterized in that: the sand inclusion layer is an ultra-thin single-layer sand inclusion resin layer; and the ultra-thin single-layer sand inclusion resin layer is formed by impregnating bag abrasive cloth wound resin into quartz sand or powdered whiting with the thickness of 1 to 2 mm. Compared with the prior art, the minor-caliber fiber reinforced plastic sand inclusion pipe has the advantages that: by adopting the ultra-thin single-layer sand inclusion layer, the pipeline rigidity of the minor-caliber fiber reinforced plastic sand inclusion pipe is effectively improved and is greater than that of other fiber reinforced plastic sand inclusion pipes with the same caliber size; besides, because the price of the quartz sand is lower than that of other raw materials, the minor-caliber fiber reinforced plastic sand inclusion pipe also has the advantages of saving raw materials and reducing the cost.

The characteristics of this small-bore RPM are:
Described burning into sand layer is ultra-thin individual layer burning into sand resin bed, described ultra-thin individual layer burning into sand resin bed is made up of the quartz sand or the powdered whiting that with pocket emery cloth winding resin dipping thickness are 1~2mm, with control duct products correlated performance, satisfy the mechanical property requirements of standard GB/T 21238-2007 " fiberglass reinforced plastics burning into sand pipe " fully, comprise pipeline axial stretching, hoop stretching, bending strength, ring stiffness, the horizontal A of deflection, the horizontal B of deflection.The quartz sand thickness of if tree impregnate with tallow is less than 1mm, and the horizontal A of RPM deflection, the horizontal B of deflection can not satisfy the mechanical property requirements of standard GB/T 21238-2007 " fiberglass reinforced plastics burning into sand pipe "; And the quartz sand thickness of resin dipping is greater than 2mm, and the manufacturing cost of RPM obviously increases.
Technical problem of the present invention is solved by following further technical scheme.
The maximum particle diameter of described quartz sand is less than the thickness of described ultra-thin individual layer burning into sand resin bed.
The maximum particle diameter of described powdered whiting is less than the thickness of described ultra-thin individual layer burning into sand resin bed.
Preferably, the particle diameter of described quartz sand is 120~830 μ m, and particle diameter is easy to miss from pocket gauze hole less than the quartz sand of 120 μ m, causes waste of material, and is difficult to control the thickness of burning into sand layer.
Preferably, the particle diameter of described powdered whiting is 106~212 μ m, and particle diameter is easy to miss from pocket gauze hole less than the powdered whiting of 106 μ m, causes waste of material, and is difficult to control the thickness of burning into sand layer.
The surface density of described pocket emery cloth is 65~85g/m 2
Described pocket emery cloth is that pure polyester thread is knitted the pocket emery cloth.
Technical problem of the present invention is solved by following further again technical scheme.
The bore of described small-bore RPM is less than 400mm.
Preferably, the bore of described small-bore RPM is 100~400mm.
Described small-bore RPM comprises small-bore burning into sand pipe and small-bore cable tube.
The beneficial effect that the present invention is compared with the prior art is:
Small-bore RPM of the present invention adopts ultra-thin individual layer burning into sand layer, effectively improves the pipeline rigidity of small-bore RPM, and its pipeline rigidity is greater than other GRP pipe with caliber size.And, since quartz sand to compare other cost of material low, also have economize in raw materials, beneficial effect that cost reduces.
