Sell Galvanized Steel Pipes (Tubes)

Description

Galvanized Steel Pipes and Tubes Galvanized Steel are those steel that has been covered with a layer of zinc metal. During galvanizing, steel is immersed in a molten zinc bath, ensuring a tough, uniform barrier coating. Zinc\'s natural corrosion resistance provides long-term protection, even in outdoor environments. Apart from preventing water corrosion, it is equally effective in dry, indoor environments.

Galvanized Steel Pipes and Tubes made of galvanized steel has long been one of the most used building materials in the world. For decades, designers, builders and consumers seeking long-term structural performance in the harshest of outdoor applications have turned to zinc-coated steel pipes. Zinc-coated galvanized steel pipes and tube resist the attack of wind, water and road salts. 3PE coating pipes

Pipe has three layer PE antisepsis structure: the first layer with epoxy powder (FBE> **0um), the second layer with adhesive (AD), **0 ~ **0um, the third layer with polyethylene (PE) 2.5 ~ 3.7mm. integration of them and solid steel pipe make form a good coating. Diameter range *0mm****0mm, wall thickness 2.***8mm, which is a good anti-corrosion method, generally can improve the service life of *0 years, not only extended the replacement cycle of the underground plumbing, and significant cost savings for the provides a strong role in nation-building. 3PE anti-corrosion is the most commonly used method of anti-corrosion, in addition to 2PE, 2PP, 3PP, their manufacturing process is similar to but different raw materials, this anti-corrosion characteristics of the simple fabrication process, the preservative effect, inexpensive pipe manufacturing industry generally agree that corrosion

3PE anticorrosive steel pipe characteristics:
1，very high tightness,which can greatly save energy, reduce costs, protect the environment in long-term operation.
2, strong corrosion resistance, the construction side simply speed, the service life can be up to ****0 years.
3, with good resistance to corrosion and impact resistance, low water absorption, the PE (less than 0.*1%) at low temperatures.
4, high strength epoxy, PE absorbent and hot melt adhesive softness, etc., have high corrosion reliability.
 

Coated steel pipe is the pipe based as the matrix melt spray or adsorption food-grade epoxy powder coating orPE raw materials at high temperature curing from new materials, through a special process in the wall.

Coated steel pipe is with excellent corrosion resistance and frictional resistance. Epoxy coated steel pipes is used for water supply and drainage, sea water, warm water, oil, gas and other medium of transportation, and polyvinyl chloride (PVC) coated steel pipe is for drainage, sea water, oil, gas and other medium of transportation.

Product features: The steel pipe is PE (modified polyethylene) hot dip or EP (epoxy) products both inside and outside coating with excellent corrosion resistance. The coating itself has a good electrical insulation and does not produce electrical erosion. Low water absorption, high mechanical strength, low coefficient of friction to achieve the purpose of long-term use. besides, effectively preventing the destruction of plant roots and soil environmental stress.

Inside and outside the coated steel pipe is dissolving layer melt in the pipe wall thickness 0.5 ~ 1.0mm polyethylene (PE) resin, ethylene - acrylic acid copolymer (EAA), epoxy (EP) powder, non-toxic polypropylene (PP) steel-plastic compound pipe, or non-toxic polyvinyl chloride (PVC) and other organic form, it not only has the high strength of steel pipes, easy to connect, resistance to water flow impact, but also to overcome the steel pipe water corrosion, contamination, scaling and plastic pipe strength is not high, and poor fire performance shortcomings of the design life of up to *0 years. The main disadvantage of not bending, thermal processing and welding cutting operation is to install the application manufacturer, the cut surface with some non-toxic room temperature curing adhesive brushing.

                                                                  BLACK STEEL PIPES

Black steel:
Black iron is the uncoated steel and is also called as black steel. When steel pipe is forged, a black oxide scale forms on its surface to give it the finish which is seen on this type of pipe. Because black steel is subject to rust and corrosion, the factory also coats it with protective oil. Those black steel are used for manufacturing pipe and tube, which will not rust for a long time and requires very little maintenance. It is sold in standard **-foot lengths TBE.

Usages of black steel pipe::
Black steel pipe is widely applicable for ordinary uses in water, gas, air and steam, black steel tubes and pipes are utilized for gas distribution inside and outside the house and for hot water circulation in boiler systems. It is also used for line pipes in oil and petroleum industries, for water wells and for water, gas and sewage purposes. It is not used for potable water or for drain waste or vent lines.

Black steel pipe:
Black steel pipes and tubes are cut and threaded to fit the job. Fittings for this type of pipe are of black malleable (soft) cast iron. They connect by screwing onto the threaded pipe, after applying a small amount of pipe joint compound on the threads. Larger diameter pipe is welded rather than threaded. Black steel pipe is cut either with a heavy-duty tube cutter or cutoff saw or by hacksaw. When steel pipe is forged, a black oxide scale forms on its surface to give it the finish which is seen on this type of pipe. Because steel is subject to rust and corrosion, the factory also coats it with protective oil. Those black steel are used for manufacturing pipe and tube, which will not rust for a long time and requires very little maintenance. It is sold in standard **-foot lengths TBE.
