The lining plastic steel pipe is based on galvanized seamless steel pipe and welded steel pipe. After the inner wall is removed, the food grade polyethylene (PE) pipe with the same diameter as the galvanized pipe is lined. The thickness of the polyethylene liner is required to meet the HG/T 20538-2016 standard.Ordering hotline: +86 153-3371-8318 / +86 133-1488-3680 Contact Us

As is known to all, steel corrosion is very common, resulting in huge economic losses. We know that the corrosion of steel is mainly due to electrochemical corrosion, plastic corrosion aging is mainly caused by chemical corrosion and ultraviolet radiation, inner steel embedded plastic liner steel tube because the inner plastic tube is protected by the outer metal tube, completely eliminate the cause of plastic corrosion aging, so that the plastic tube has a durable performance. The outer metal tube is much more difficult to protect. Three layers of corrosion prevention measures are adopted on the outer surface of the embedded plastic steel tube with inner reinforcement: the first layer is galvanized layer, and the steel tube forms a cathode to protect against rust. The second layer: epoxy primer, which forms a dense polymer protective film on the surface of the galvanized layer to isolate it from the air and water, slow down the oxidation corrosion of the zinc layer, and thus improve the service life of the pipe. The third layer: finish coat, strengthen the protective effect of the film, improve the beauty of the product. Appropriate anti-corrosion measures should be taken to improve the service life of the system when it is used in underground. It can also be used in the line of plastic steel pipe as the base pipe, the outer surface is covered with a layer of plastic pipe "inner reinforcement embedded double-sided lining steel pipe" (PE pipe + carbon steel pipe +PP pipe series products directly buried use.
Application: widely used in petroleum, chemical industry, chemical fiber, chlor-alkali, dyestuff, pesticide, medicine, environmental protection, smelting, electric power and other industries medium transport and environmental protection treatment system, domestic drinking water supply and distribution pipeline, sea water transport pipeline, sewage transport pipeline, shipbuilding and other water transport pipelines.

Pressed corrugated steel sheet (roofing sheet) refers to the steel sheet formed by cold pressing or cold rolling. The steel sheet is made of coloured steel sheet, galvanized steel sheet, stainless steel sheet, aluminium sheet, anticorrosive steel sheet or other thin steel sheet. The profiled steel sheet has the characteristics of light weight, high strength, low price, good seismic performance, fast construction and beautiful appearance.The corrugated metal is a good building material, mainly used for guardrail, floor and other buildings, such as airport terminal, railway station, stadium, concert hall, grand theatre, etc. According to different application requirements, the profiled steel sheet can be pressed into a wave type, a T type, a V type, a rib type and the like. Main Features 1.Rich color:Beautiful shape, rich color, strong decorative, flexible combination, can express different architectural styles; 2.Light weight:Light weight (6-10 kg/m_) high strength (yield strength 250-550 MPa), good skin stiffness, good anti seismic performance of waterproofing agent. 3.Safe and convenient:Construction and installation is convenient, reducing installation and transportation workload, and shortening construction period. 4.Environmental protection:Recyclable and popularized application of profiled steel sheet to meet the sustainable development policy of the national economy.Read more
PPGL Coil is a new material produced in recent years due to high-end applications,commonly referred to as CCLI. Aluminum-galvanized steel sheet (55% aluminium, 43% zinc and 1.6% silicon) with better corrosion resistance than galvanized steel sheet is used as the base plate. After surface degreasing, phos-phating and complexes treatment, the organic coating is applied to the products made by baking. Buildings: roofs, walls, garages, sound insulation walls, pipes and composite houses, etc. Automobile: muffler, exhaust pipe, wiper accessories, fuel tank, truck box, etc. Appliances: Refrigerator back plane, gas stove, air conditioner, electronic microwave oven, LCD frame, CRT explosion-proof belt, LED back light, electrical cabinet, etc. Agricultural: pigsty, chicken house, granary, greenhouse piping and other: heat insulation cover, heat exchanger, dryer, water heater, etc.Read more
