FRACTURING FLUID TRANSPORT HOSE, METHOD FOR MANUFACTURING SAME, AND CO-EXTRUSION MOULD

摘要

The present invention provides a fracturing fluid transport hose, a method for manufacturing same, and a co-extrusion mould. The method for manufacturing a fracturing fluid transport hose according to the present invention includes the following steps of: (1) drying, agitating and color matching of an outer adhesive layer; (2) drying, agitating and color matching of an inner adhesive layer; (3) producing a reinforcement layer: knitting a tubular reinforcement layer according to a product design specification parameter; and (4) producing a final product: sleeving the reinforcement layer on a mould core of a co-extrusion mould, suctioning the dried granules in step (1) and step (2) into two extruders respectively, and starting the extruders and a dragger, so that the reinforcement layer, the outer adhesive layer granules and the inner adhesive layer granules pass through a co-extrusion device together to obtain a product. Different types of materials may be used as the outer adhesive layer and the inner adhesive layer of the present invention, and different combinations of outer adhesive layer and inner adhesive layer materials can meet more needs and also lower product costs. The hose can be produced in any length and has small elongation. The product has a stable size. The hose can bear great pressure and transport a large flow, can be easily connected, and has a small volume for storage and transport.

1. A method for manufacturing a fracturing fluid transport hose, wherein the method comprises the following steps of:
(1) drying, agitating and color matching of an outer adhesive layer: putting outer adhesive layer granules and color masterbatch granules into an agitator in a proportion of 100:(0-1.5), agitating the outer adhesive layer granules and the color masterbatch granules, then suctioning the outer adhesive layer granules and the color masterbatch granules into a dryer, and drying the outer adhesive layer granules and the color masterbatch granules in a temperature of 70to 110° C. for 1 to 6 hours; (2) drying, agitating and color matching of an inner adhesive layer: proportionally putting inner adhesive layer granules and color masterbatch granules into an agitator, agitating the inner adhesive layer granules and the color masterbatch granules, then suctioning the inner adhesive layer granules and the color masterbatch granules into a dryer, and drying the inner adhesive layer granules and the color masterbatch granules in a temperature of 70 to 110° C. for 1 to 6 hours; (3) producing a reinforcement layer: knitting a tubular reinforcement layer according to a product design specification parameter; and (4) producing a final product: sleeving the reinforcement layer on a mould core of a co-extrusion mould, suctioning the dried granules in step (1) and step (2) into two extruders respectively, and starting the extruders and a dragger, so that the reinforcement layer, the outer adhesive layer granules and the inner adhesive layer granules pass through a co-extrusion device together to obtain a product.
