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:25 of the steel pipe with 6 in charge of what is the difference?
25 of the steel pipe with 6 in charge of the difference:25 of the steel pipe refers to the DN25 tube, the outer diameter of 25mm; 6, in charge of refers to DN20 steel pipe, the outer diameter is 20mm.
Q:Steel pipe is particularly long, how to clean the inner wall of the pipe so that it can be thoroughly cleaned
If the pipe is relatively long, you have water, you can buy ultrasonic vibration plate into the water for ultrasonic cleaning, if not too long with an ultrasonic vibration rod, inserted into the pipe cleaning, and then rinse with water by ultrasonic stripping of dirt, give you recommend a factory in Jining Hengda
Q:What is a tight steel tube?
The tight steel tube is called "galvanized steel pipe with sleeve connection" or "flat pipe of steel metal for electrical installation". JDG. The utility model relates to a novel protective conduit for an electric circuit. The connecting sleeve and the metal accessory are provided with a wire pipeline composed of screw fastening connection technology, and the utility model does not need to do cross grounding, welding and covering, and the appearance is silvery white or yellow.
Q:How to calculate the maximum bending stress of steel pipe? Is there a list of the maximum flexural normal stresses for steel pipes of different materials and diameters?
Wnx - net sectional modulus of steel tubes, also called net sectional resistance moment. If the section is not weakened, it can be found in the steel sheet of the steel structure design manual. If the section is weakened, it can be calculated by the formula according to the sectional dimension according to the formula of the material mechanics.
Q:How to descaling galvanized steel pipe?
If the substrate is rusty, rust removal can be removed by acid leaching. If the coating is rusted, it can also be dipped in acid, but this will also remove the coating and make the base material more susceptible to rust, preferably by re plating and passivation
Q:Are the welded and galvanized tubes the same weight?
The same specifications of welded pipe and galvanized pipe weight is not the same, the general welding tube weight, galvanized pipe light.
Q:How to perform nondestructive inspection of steel tubes
Including fluorescence, coloring two kinds. Because of its simple equipment and convenient operation, it is an effective method to check the surface defect of magnetic particle inspection. It is mainly used for surface defect inspection of non-magnetic materials.
Q:Difference between seamless steel pipe and welded pipe
Welded steel pipe for different welding process and divided into the furnace pipe welding (ERW) pipe and automatic arc welding, because of the different forms of welding seam welded pipe and spiral welded pipe is divided into two kinds, end its shape is divided into circular welded and shaped (square) pipe etc..
Q:Does seamless steel tube have a bend of 135 degrees?
In engineering, it is usually marked as "45 elbow" and has no "135" mark. The angle of the elbow is acute, so there will be no more than 90 degrees elbow.
Q:What's the difference between steel pipe and pipe fittings?
Pipe classification: steel pipe seamless steel pipe and welded steel pipe (tube) two categories. It can be divided into round tube and special-shaped tube according to the sectional shape. The round steel tube is widely used, but there are some special-shaped steel tubes such as square, rectangle, semicircle, hexagon, equilateral triangle and octagon.
