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:What is the single length of galvanized steel pipe?
Hot dip galvanized steel pipe is widely used in fire, power and highway.
Q:How can two smooth steel pipes be joined? The size of the two pipe is different (except for welding)
Fastener type steel pipe scaffold, fastener is the connection between steel pipe and steel pipe, and its form has three kinds, namely right angle fastener, rotating fastener, butt fastener
Q:What is the production process of seamless steel tube?
Main production process of cold rolled (drawn) seamless steel tube:Blank preparation, pickling, lubrication, cold rolling (drawing), heat treatment, straightening, finishing and inspectionThe 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:What's the use of steel pipe?
Steel pipe is not only used to transport fluid and powder solid, exchange heat energy, and manufacture mechanical parts and containers, but also is an economic steel. It can reduce weight and save 20 to 40% of metal by using steel pipe to make building structure, network frame, prop and mechanical support. Moreover, it can realize factory mechanization construction. (
Q:What does "buried steel pipe" 6*2SC100 mean?
The embedded steel pipe 6*2SC100 refers to a welded steel pipe with 2 pipe thicknesses of 6mm and a diameter of 100mm. SC pipe means welded steel pipe. Embedment means pre installation (burial).
Q:Is there a weld on the outer wall of seamless steel tube?
As you have said this, you have to fake goods is seamless, commonly known as to seamless steel pipe, seamless steel pipe is welded pipe weld reinforcement, and then go inside and outside the weld is worn away, and then burn side is that you say is that, after you can see the wall friction of a weld, is not too obvious. Like a polished, but no wall bulge, can not see the seam,
Q:What does the diameter of a steel pipe project mean?
Generally, the diameter of steel pipe has three common diameters: outer diameter, inner diameter and nominal diameter.The first two are well understood.Nominal diameter refers to the national standard to specify the general diameter of a certain national standard pipe. It is only a model representation. It is neither outer diameter nor inner diameter.
Q:What is the process of spiral steel tube production?
Butt welding: the use of advanced double submerged arc welding technology for pre welding, internal welding, external welding. The welded steel tubes are cut into standard lengths using a plasma gage.
Q:Steel pipe is particularly long, how to clean the inner wall of the pipe so that it can be thoroughly cleaned
High cleanliness requirements for ultrasonic cleaningUltrasonic cleaning principle: the pressure change of ultrasonic wave propagation in the liquid in the liquid cavitation phenomenon strongly, per second produced millions of tiny gas bubbles, these bubbles rapidly in large pressure under the action of not following the violent explosion, impact force and produce strong suction, enough to make the stubborn dirt quickly stripped.
Q:Galvanized steel pipe in addition to good rust resistance, what are the advantages?
First, the surface of the steel pipe is treated by embroidery, which is more durable, not faster than the rapid oxidation, and will not form white rust on the steel tube;Two. The steel pipe is fully protected. After heating, each part of the steel pipe is plated with zinc, and the concave convex part is protected;
