Example Embodiment

[0009] In the microstructure of the plastic pipe, the orderly high-performance condensed structure of polymers such as macromolecules 1, oriented crystalline skewers 2 and oriented crystalline skewers interlocking structure 3 in the circumferential direction of the pipe axis, is effective The strength, stiffness, modulus, and pressure resistance of the pipe in the axial and circumferential directions are enhanced; at the same time, the macromolecules 1, which are oriented along the circumferential direction of the pipe axis, 1, the oriented crystals, and the oriented crystals, are interlocked. The ordering behavior of structure 3 also improves their crystallinity, and the thickness of the wafer is also thickened, so the temperature resistance of the pipe is also improved.

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 bidirectional 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 and bidirectionally reinforced in the axial direction and the circumferential direction, the weld mark defect is eliminated, both the strength and the modulus of the pipe in the circumferential direction can exceed or approach those of the pipe in the axial direction, the performance of a material is more optimally configured, and the actual demand of the pipe under internal pressure on material performance is met better. After reinforcement, the orientation degree of the pipe in the axial direction and the circumferential 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...
