Abstract
The invention relates to a composite pipe, in particular to a nylon pipe for a zinc-plating spiral steel liner, consisting of a zinc-plating spiral light reinforcing pipe and an MC (Methyl Cellulose) nylon layer from outside to inside. MC nylon in a zinc-plating spiral steel composite nylon pipe is centrifugally cast on an inner wall of the zinc-plating spiral light reinforcing pipe. The nylon pipe is characterized in that the inner wall of the zinc-plating spiral light reinforcing pipe is threaded, so that the adhesive strength of the nylon and the zinc-plating spiral light reinforcing pipe is increased, and the expansion stretching coefficient of the nylon can be reduced. A crest spiral reinforcing rib is adhered to the outer wall of the zinc-plating spiral light reinforcing pipe, so that the strength of the zinc-plating spiral light reinforcing pipe is increased, and the production cost is reduced. The nylon pipe provided by the invention has the advantages of high strength, good wear resistance, large adaptive temperature range ( minus 50 to 150 DEG C), small smooth fluid abrasion of an inner wall, non-toxicity, no secondary pollution, no scale formation, convenience in construction and installation, long service life and the like.
Description
Technical field
The present invention relates to a kind of composite pipe, particularly relate to a kind of zinc-plated spiral steel lining nylon tube.
Background technique
In the prior art; Tradition steel lining nylon tube generally is made up of outer layer pipe and internal layer nylon, and nylon adopts both MCPA monomer cast nylons of MC nylon, also is cast nylon; Can be directly raw material be injected in the mould of preheating and carry out polymerisation and coagulation forming rapidly, process the MCPA monomer cast nylon.It is a kind of novel engineering plastics, and this material is that a kind of intensity is high. good rigidly, and density is little, and is wear-resisting, antifriction, oil resistant, corrosion-resistant, be easy to machine shaping, moderate macromolecule engineering plastics.But temperature process control is required than higher, and control bad can cause nylon tube and steel pipe layering, and externally temperature influence meeting to nylon tube expands and ruptures.
Summary of the invention
Technical problem to be solved by this invention is the deficiency to existing technology, and a kind of zinc-plated spiral steel lining nylon tube is provided.
The technological scheme that the present invention adopts is:
A kind of zinc-plated spiral steel lining nylon tube is made up of zinc-plated spiral lightweight reinforcement tube, MC nylon layer from outside to inside; The spun casting of MC nylon is at zinc-plated spiral lightweight reinforcement tube inwall in the zinc-plated spiral steel composite nylon pipe; It is characterized in that zinc-plated spiral lightweight reinforcement tube inwall adopts numb line shape, has increased the adhesion strength of nylon and zinc-plated spiral lightweight reinforcement tube; Can reduce the expansion coefficient of dilatation of nylon; Overcome external temperature and change the phenomenon that makes nylon tube expand and rupture, reduced the use amount of steel, strengthened antiseptic property.
Described zinc-plated spiral lightweight reinforcement tube outer wall is attached with the crest spiral reinforcing rod, strengthened zinc-plated spiral lightweight reinforcement tube intensity, lowered cost of production, the weight ratio common steel tube can alleviate 30%.
The present invention has the intensity height, wear resistance is good, (50 ℃-150 ℃), inner wall smooth fluid grind advantages such as resistance is little, avirulent, no secondary pollution, non-scaling, construction install convenience, long service life to the adaptive temperature scope greatly.
Description of drawings
Fig. 1 is a section of structure of the present invention.
Fig. 2 is a structural representation of the present invention.
Embodiment
As shown in Figure 1, zinc-plated spiral steel lining nylon sleeve is made up of zinc-plated spiral lightweight reinforcement tube 1, MC nylon layer 3 from outside to inside.3 spun castings of MC nylon are at zinc-plated spiral lightweight reinforcement tube 1 inwall in the zinc-plated spiral steel composite nylon pipe; Zinc-plated spiral lightweight reinforcement tube 1 inwall adopts numb line shape 2; Increased the adhesion strength of MC nylon 3, can reduce the expansion coefficient of dilatation of MC nylon 3, overcome external temperature and change the phenomenon that makes nylon tube expand and rupture with zinc-plated spiral lightweight reinforcement tube 1; Reduce the use amount of steel, strengthened antiseptic property; Outer 1 wall of zinc-plated spiral lightweight reinforcement tube is attached with crest spiral reinforcing rod 4, strengthened zinc-plated spiral lightweight reinforcement tube 1 intensity, lowered cost of production.
The present invention is applicable on the pipelines such as salt solution, ammonial brine, Zhong Heshui, cold mother liquor, condensed fluid, ammonia, seawater.
