water pipeline inner-layer tape

State-of-the-Art Pipeline Protection for All Climates & Environments

System description:

WATER PIPELINE Inner -layer tape also be called pipe wrap anti-corrosion tape, polyethylene wrap tape.

water pipeline Inner-layer tapeT100 is engineered to assure a high bond to the primed pipe surface with excellent conformability characteristics, aggressive adhesive for corrosion protection and repair of main line coatings.

Inner-layer tapeT100 series is cold applied tape coating system for corrosion protection of Oil, Gas, Petrochemical, and Waste Waterburied pipeline, pipe can be buried, also can be underground ,overhead ,onshore and offshore .

Structure of water pipeline inner wrap tape
The specification of the tape consists of two layers, adhesive layer and film backing
Adhesive: butyl rubber
Film backing: Special blend of stabilized polyethylene

Q:The difference between carbon and welded steel tubes
Seamless steel pipe because there is no weld, so can withstand greater pressure, boiler tubes are generally used seamless steel pipe
Q:Where is the difference between seamless steel pipe and welded pipe
Seamless steel tube is formed during rolling. Welded steel pipes need to be welded after coiling, and spiral welding and direct welding are generally used. Seamless performance is better, of course, the price is higher.
Q:Galvanized steel pipe, PPR pipe, PE pipe, U-PVC pipe and HDPE double wall corrugated pipe and what is the difference between the characteristics of
Galvanized steel pipe is a kind of antirust steel pipe, often used in relatively high water supply pipeline or hot water pipeline, the price is higher, can use for at least 30 years;PPR pipe is a kind of polypropylene plastic, which is commonly used in environmental protection plastic pipes, but only suitable for low temperature occasions. It is mainly used for water supply;
Q:Stainless steel tube, also known as why tube?
According to the end of the pipe can be divided into light pipe and wire tubeThe tube can be divided into ordinary tube and special thread tube
Q:What quota is reserved for buried DN20 steel pipe?
If it is reserved for embedded pipe pre buried steel waterproof casing, set of waterproof casing steel production and installation is to set the quota items, if the outdoor installation of welded steel pipe buried steel casing pre quota items, if it is a reserved hole, then there is no need to set the quota items.
Q:When can I use the PVC pipe and when to use the galvanized pipe?
Galvanized pipes are generally used outside the drying environment or building blocks, and PVC is mainly used for pre embedding in walls or humid environments. If in the ceiling ceiling, below the roof, you need to use galvanized pipe, in the floor below, on the ground you need to use PVC.
Q:What does seamless steel tube mean? What are the main uses? What are the classifications?
The production process of seamless steel tube in general can be divided into two kinds of hot rolling and cold drawing, cold-rolled seamless steel pipe production process than hot-rolled billet to complex, first to three roller rolling and extrusion to sizing test, if the tube through the cutting machine cutting surface without crack growth response after cutting blank about one meter. Then enter the annealing process, annealing and pickling to use acid pickling liquid, should pay attention to the surface if there are a lot of bubbling, if there are a large number of bubbling pipe shows that the quality is not up to the standard. The appearance of cold rolling seamless steel tube shorter than hot-rolled seamless steel pipe, cold rolled seamless steel pipe wall thickness is generally higher than hot-rolled seamless steel pipe to be small, but the surface looks better than thick wall seamless steel pipe is more bright, rough surface is not too much, not too much burr diameter.
Q:How can seamless steel tubes be produced?
The material of rolling seamless tube is round tube blank, and the billet is processed by cutting machine to grow about 1 meters, and sent to the furnace by conveyor belt. The billets are heated into a furnace and the temperature is about 1200 degrees celsius. The fuel is hydrogen or acetylene. The temperature control in the furnace is a key problem. When the round billet is released, it should be punched through the pressure piercer. The most common punching machine is a cone roll piercer, which has high production efficiency, good product quality, large perforation and expanding diameter, and can be used in various steel grades. After the perforation, the round tube blank has been successively rolled, rolled or squeezed by three rollers.
Q:Can seamless steel pipe and ordinary steel pipe be welded?
Steel pipe and seamless linking points, you said should refers to ordinary steel pipe joints, if only consider the butt welding problem, two kinds of steel can be welded. But the mechanical properties of the seamless steel pipe and tube with different, generally the main difference is the two kinds of steel can withstand the pressure of the former than the latter to be good.So if your project is seamed steel pipe can be, then the two pipe welding, welding and butt welding interface is completely no problem.
Q:What type of steel pipe for security windows?
General anti-theft window through the round tube is 3 cm square tube, 22.5 mm diameter round tube, also can use all square tube to do, if you want to median 304, the pipe is estimated more expensive, the market to do the price in 60 to 110 range. As for plastic steel, Anhui conch brand, the price of 180 this way. Aluminum alloy 110 to 230 specific look what material?!
