Precautions for using cold-wrapped anticorrosion tape Pipeline is very susceptible to external corrosion, in fact, the protection of the pipeline is very easy, only need to use the cold wrapped anti-corrosion tape to do a good job on the pipeline appearance of the protection can be, easy, fast and simple, in the process of use we just need to pay attention to these points of attention to it. Here are some detailed notes. 1, in the construction of the need for deconvolution, deconvolution of the temperature should be controlled at 5 degrees above the more appropriate. 2.When wrapping cold wrapping anticorrosive tape, try to use mechanical wrapping tape, which can ensure the construction quality. 3, in the process of winding the tape, make sure the tape has a certain tension, so that the adhesive layer of the tape can be tightly combined. 4, the first is the surface treatment of the problem, in construction to deal with the surface, such as welding slag on the surface of the pipeline and some other attachments, are to clean up, especially some of the overhaul of the pipeline should also be cleaned up. 5, if the transportation to the phenomenon of cold wrapped anti-corrosion tape is not used immediately, it needs to be stored, when stacking the tape to not destroy the anti-corrosion layer as a principle, prompted by the anti-corrosion layer can be padded between the soft substances. 6, and then there is the work of mending and mending, in the repair to repair the damaged parts, you can use the winding method of mending and mending, mending to remove the loose part of the anticorrosion layer, and mending to keep the dry place is better. These precautions as long as we pay attention to, then the construction of cold wrapped anticorrosive tape is basically no problem, although its anticorrosive effect is strong, however, if you do not pay attention to the above precautions, then there is a high probability that the construction effect deteriorates, so we must pay attention to the above precautions.

Liquid Primer---How to ensure the quality of the primer coating of polyethylene corrosion-resistant tape The quality of anticorrosive primer has a vital influence on the anticorrosive effect and life, so the quality of primer must be guaranteed in the construction of the tape.The following is the method to ensure the quality of the primer of polyethylene anticorrosive tape, and the specific operation can be carried out according to the following. 1, when the pipe surface pretreatment, must be within 6 hours of the anticorrosion primer painting construction, and to ensure that the pipe surface is dry, dust-free. 2, be sure to ensure that the consistency of the primer is appropriate, if it is too thick can be added to the matching thinner to dilute, and then paint. 3, in the construction of the primer must ensure that no leakage of paint, no bubbles, condensation and hanging, and the thickness is greater than or equal to 30 microns. 4, in the lower temperature environment or trench construction, should be appropriate to extend the surface drying time, to ensure that the lower part of the pipe surface dryness. The above is the key to ensure the quality of the primer coating of polyethylene anticorrosive tape, so during the construction of the tape, it must be carried out in strict accordance with the specified operational requirements to ensure the use of the tape and the extension of its life.

Precautions for the construction of viscoelastic anticorrosive tape Viscoelastic anticorrosive tape developed byJining Xunda Pipe Coating Materials CO.,Ltd, the leading brand of anticorrosive tape in China. It is a new product of anticorrosion. Pay attention to the following matters when using it: The quality of the tape and the outer protective tape installation of the viscoelastomer anticorrosive tape should be made to achieve a smooth surface, even lap joints, there can be no bubbles, wrinkles and breakage, so a good construction will also help the performance of the product. First of all, the surface of the pipe body should be treated. Under the condition that the temperature and air humidity meet the construction requirements, the surface of the pipe body is cleared of floating rust by mechanical descaling equipment, and the descaling grade reaches ST2.After descaling, the surface of the pipe body is dried by a hot blower. It is wrapped with viscoelastic anticorrosive tape, in the completed surface treatment of the pipe section wrapped with a layer of viscoelastic anticorrosive tape, the end of its lap length with the original coating is not less than 50mm. from the end to one side of the order of winding, anticorrosive tape joints the minimum lap length of 10mm. Wrapped with viscoelastic anticorrosive tape, do not have to maintain a large tension, and the edge of the tape and the lap part of the tape can be pressed with the hand. For the anticorrosion work of valve flange and other joints, you can use anticorrosive paste to fill the connecting bolts flat, and then use the viscoelastic anticorrosive tape for wrapping treatment.

Instructions For The Use Of Viscoelastic Anti-corrosion Tape and Viscoelastic Paste 1.Surface treatment The surface rust is removed by mechanical descaling equipment (electric angle grinder) to a level of ST2. After descaling, the surface of the pipe is dried using a hot blower. 2.Anti-corrosion tape with viscoelastic wrapping around the pipe body Wrap a layer of viscoelastic anti-corrosion tape around the completed surface treatment section, with a lap length of not less than 50 mm from the end to one side, with a minimum lap length of 10 mm at the joint of the anti-corrosion tape; it is not necessary to maintain a high tension when wrapping viscoelastic anti-corrosion tape, but it is sufficient to press the edge of the tape and the lap part by hand. 3.Anti-corrosion tape with viscoelastic around flanges and other shaped parts For anti-corrosion work at connections such as valve flanges, anti-corrosion paste can be used to fill the connection bolts flat and then wrap them with viscoelastic anti-corrosion tape. 4.Wrap-around protective tape The basic operation method is the same as the construction of the viscoelastic anti-corrosion tape, but when winding the outer protective tape to maintain a certain tension, the amount of lap in the joint part is 50%, the ends of the anti-corrosion pipe section are exposed 1 to 2mm, without winding the outer protective tape. 5.Quality inspection Quality requirements for the installation of viscoelastic anti-corrosion tape and external protective tape: flat surface, even laps, no bubbles, wrinkles and breakage.

Product properties of polyethylene anti-corrosion tape Polyethylene anti-corrosion tape with high viscosity and good insulation is based on PE film with a shiny or matt surface, soft and flexible, good insulation, good adhesion and stable electrical insulation in humid environments and water. The following are four properties of polyethylene anti-corrosion tape. 1, good insulation performance: polyethylene anti-corrosion tape has high electrical insulation and low water absorption and moisture leakage rate. 2, strong bonding: polyethylene anti-corrosion tape and steel pipe have enough bonding force, can be good to prevent liquid medium penetration into the surface of the steel pipe, buried for many years can still maintain a high bond strength. 3, elongation ductility: tape has a good elongation at break and ductility, in a wide range of temperatures can maintain its flexibility. 4, high cathodic stripping resistance: polyethylene anticorrosive tape anticorrosive layer has good resistance to cathodic stripping performance, adhesive tape anticorrosive pipeline has a reliable protection potential and stable protection current. So it can be seen that polyethylene anticorrosive tape is because of the above-mentioned points of superior performance, and thus popular with the majority of users, but again good products also need to be used correctly in order to give full effect to its role .

Equation for pipe coating requirements When the the pipeline need corrosion protection, we will need the pipe coating ,but we do not know the pipe coating requirement , here is the equation for pipe coating requirements :
