Temperature-resistant pressure-resistant axial self-reinforced plastic pipe special for oil treatment

Abstract

The invention relates to a structural composition of various plastic pipe parts. The structural composition is characterized in that: a plastic pipe has temperature-resistant pressure-resistant performance due to a high-performance condensed-state structure which has a self-reinforcing function and comprises polymers such as macromolecules, shish-kebab, interlocking shish-kebab and the like on the premise of not comprising any other extra reinforcing agent, wherein the polymers are oriented and crystallized along the axial direction of the pipe. When the strength and the modulus of the pipe are simultaneously reinforced in the axial direction, the actual demand of the pipe on material performance is met better. After reinforcement, the orientation degree of the pipe in the axial direction is also higher than that of the conventional pipe, the wafer of the reinforced pipe is thicker, and the crystallization degree is higher, so that the temperature resistance is also obviously improved compared with that of the conventional pipe, and the pipe is particularly suitable for a pipeline special for oil treatment. The pipe has the advantages of high production efficiency, small equipment investment, low raw material cost, low production cost and high product performance, can accord with the industrial production conditions and has better industrial prospect and economic benefit.

Description

Technical field: [0001] The technology relates to various plastic pipe parts, in particular to a temperature-resistant and pressure-resistant circumferential self-reinforced plastic pipe specially used for oil treatment, and belongs to the field of microstructure of plastic parts. Background technique: [0002] In the process of waste oil recycling and re-refining, the pipelines transporting oil not only need to withstand corrosion, but also often need to withstand certain pressure and temperature. However, plastic pipes are plastic products after all, and their rigidity, strength and temperature resistance are far inferior to cast iron pipes. In order to meet the application in waste oil recycling and re-refining process, it is necessary to improve the compressive strength and temperature resistance of plastic pipes. If the ordinary method is used to improve its strength, the wall thickness of the pipe must be increased, but the increase of the wall thickness will bring abo...
