Abstract
The invention discloses a seamless steel tube for cold and hot drinking water. The seamless steel tube comprises a steel tube body, a glass-fiber-reinforced thermoplastic plastic layer, a hollow glass microbead/epoxy resin composite material layer, a graphene oxide/phenolic resin layer and an anti-ultraviolet nano-zinc oxide-epoxy resin composite material layer, wherein the graphene oxide/phenolic resin layer and the anti-ultraviolet nano-zinc oxide-epoxy resin composite material layer are arranged on the outer wall of the steel tube body in sequence, and the glass-fiber-reinforced thermoplastic plastic layer and the hollow glass microbead/epoxy resin composite material layer are arranged on the inner wall of the steel tube body in sequence. The seamless steel tube integrates the advantages of a reinforced concrete tube and the advantages of a plastic tube, and is light, good in compression resistance and ageing resistance and durable, and a joint is not prone to leakage.
Description
Technical field
The present invention relates to seamless steel pipe field, particularly relate to a kind of seamless steel pipe for cold and hot potable water.
Background technique
Current China rapid economic development, various products are abundanter, and living standards of the people improve constantly.But the most basic daily life problem of water consumption of the mankind also often perplexs us, especially affects the tubing problem of one of indoor and outdoor feedwater quality key factor.Development with China's building plumbing system specialty is the same, China's water-feeding pipes has also experienced that kind is single, sanitary standard is low, the past of slow development with numerous in variety, sanitary standard improves soon, more new development is present rapidly.Continued to use the not Coating Steel Pipe of nearly three more than ten years, comprised and be once considered the Coating Steel Pipe that improves one of building standard class symbol, by most laboratories, partly eliminated now; For saving steel, the concrete reinforced pipe that the fifties is promoted the use of, can bear higher working pressure, corrosion-resistant, cheap, durable in use, can not reduce the conveyance power of water of water pipe, but from great, quality is hard and crisp, be afraid of collision, interface easy to leak, pipe trench bottom of trench smooth solid require high, accessory lacks to maintenance in the future increases difficulty, and consumption reduces just gradually now; The advantages such as plastic tube has anticorrosion and shock resistance preferably, has the elasticity of certain stretching-resisting bending-resisting song, and smooth surface hydraulics is good, and freexing tolerance can be stronger than metal tube, lightweight.Because tubing bearing capacity is not high enough, matter is crisp easily aging, and expensive, only for indoor small-bore pipeline.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of seamless steel pipe for cold and hot potable water, integrates the advantage of concrete reinforced pipe and plastic tube, and lightweight, compression resistance is good, and interface is easy to leak not, and aging quality resistance is good, durable in use.
For solving the problems of the technologies described above, the technological scheme that the present invention adopts is: a kind of seamless steel pipe for cold and hot potable water is provided, comprise: steel pipe body, fiber glass thermoplastics layer, hollow glass micropearl/epoxy resin composite material layer, graphene oxide/phenolic resin layer and anti-ultraviolet nano zinc oxide-epoxy resin composite material layer, on the outer wall of described steel pipe body, be disposed with described graphene oxide/phenolic resin layer and described anti-ultraviolet nano zinc oxide-epoxy resin composite material layer, on the inwall of described steel pipe body, be disposed with described fiber glass thermoplastics layer and described hollow glass micropearl/epoxy resin composite material layer.
