Installation method
Prefabricated professional composite thermal insulation exterior protection has reserved overlaps for straight pipes and pipe fittings (elbows, tees, pipe caps, etc.). Install pipe fittings (elbows, tees, pipe caps, etc.) first, then install straight pipes. If you choose glue installation, apply the special glue along the inner wall of the overlapping outer layer and away from the outer edge in the length direction using a catheter or a small needle to form a straight line. Be careful not to use too much glue, and do not break if there are sealing requirements. Line, do not use a small brush to apply glue, use a small catheter. Then align, close and overlap, it will take about seconds. During construction, pay attention to keeping the insulation shell neat and flat. Pay attention to the overlapping direction of the seams according to the needs of the actual application to make the effect beautiful and avoid dust accumulation or water entering during flushing. If you choose double-sided tape for installation, apply the special tape evenly along the inner wall of the overlapping outer layer and away from the outer edge along the length direction to form a straight line, then wrap the pipe, and tear off the double-sided tape when aligning and closing it. Just press the outer paper evenly along the length direction, and then use glue to jump the points to make it more closely connected and firm. If you choose special threaded nails (special self-tapping screws), apply the special super-adhesive tape evenly along the inner wall of the overlapping outer layer and away from the outer edge along the length direction to form a straight line, then wrap the pipe and align it. When closing, peel off the outer paper of the double-sided tape and press it evenly along the length. Then use a small cross screwdriver or the tip of scissors to first make holes of appropriate size, and then use a cross screwdriver to screw in threaded nails at certain intervals. . This special threaded nail is rust-resistant and corrosion-resistant, can be disassembled and reused for easy maintenance. Finally, you can check the seam effect to see if it needs to be combined with jump glue to make the seam tighter and stronger.
During construction, pay attention to aligning the insulation shell. Pay attention to the overlapping direction of the seams according to the needs of the actual application to make the effect beautiful. The overlap between the two outer protection sections should be bonded with glue points. Insulation pipes need to consider thermal expansion and contraction. When covering the straight pipe with insulation layer, it should not be too tight but should be slightly loose. At the same time, the outer protection of the two straight pipes should be overlapped at a certain length (for example, every meter) along the direction of the pipe. No glue is used for bonding, only the left and right sides are overlapped, leaving room for expansion and contraction.
The installation sequence of straight pipes and pipe fittings is to install pipe fittings (elbows, tees, pipe caps, etc.) first, and then install straight pipes to make the lap lines neat.
, pipe cap (blocking, plug) When installing the pipe cap or plugging, the small size pipe cap is oval. In this case, just cut the pipe cap from the middle but do not cut it at the edge. It is convenient to adjust the size. Use scissors to cut it into a circle as needed according to the outer diameter of the pipe. At the same time, cut the overlapping part of the edge of the pipe cap into petals, fold it inward slightly, wrap it with double-sided tape, and then install it on the inner wall of the straight pipe where needed. (That is, the straight tube covers the tube cap). When aligning and closing, peel off the outer paper of the double-sided tape and fix it, then add some glue. For round pipe caps that match the pipe diameter, there is no need to cut it in the middle. Just cut the overlapping edge of the pipe cap into petals, fold it inward slightly, wrap it with double-sided tape, and then install it on the inner wall of the straight pipe and align it. When closing, peel off the outer paper of the double-sided tape and fix it, then add some glue.
, Reducing diameter, (large and small heads)
For external protection of the reducing diameter (large and small heads), a section of formed straight pipe can be used, and a pipe cap is added on both sides to realize the diameter reduction. This is an economical and flexible method. See above for pipe cap installation. When making a large or small head, just cut the pipe cap from the middle, but do not cut at the edge to adjust the size. Use scissors to cut the outer diameter of the pipe into a circle and the inner circle of the small head as needed, and then cut the edge of the pipe cap Cut the overlapping part into petals, fold it slightly inward, wrap it with double-sided tape, and then install it on the inner wall of the straight pipe (that is, the straight pipe covers the pipe cap) where needed. When aligning and closing, peel off the outer paper of the double-sided tape. And fix it well, then add some glue.
, Flange (union joint)
The external protection of the flange (union joint) can be achieved by using a section of formed straight pipe and adding a pipe cap on both sides. The details are the same as the installation of large and small heads. , Super large specifications, elbows are made on-site. The elbows can be made by the straight pipe tangent method or the shrimp waist pipe method. The basic principles are similar to sheet metal, and professional sheet metal workers can provide guidance.
Use the straight pipe tangent method to cut two sections of straight pipe into pairs, and then directly install and connect them. The joints can be filled with white silicone (Tao Corning white mildew-proof silicone, acidic is recommended), or bonded with glue. This method can be applied to any degree of elbow installation. As shown in the legend.
The shrimp waist pipe production method is to lay out the straight pipe into sections according to the degree of the elbow, and cut the laid out straight pipe into sections. This method is the same as the method of making shrimp waist tube with iron sheet.
The elbow can be made using the shrimp waist tube making method. The basic principles are similar to sheet metal, and professional sheet metal workers can provide guidance.
, valves, tees Standard valves and tees, optional molded valves and tee insulation shells. The on-site production of non-standard prefabricated professional composite insulation exterior materials is very convenient, and is much more convenient than on-site production of metal.
, Irregular body
Due to the advantages of its own material, prefabricated professional composite insulation exterior materials can be easily adapted to the actual shapes of actual engineering pipelines and equipment (such as irregular valves, large and small heads, tees , Tianyuan place, storage tank, heat exchanger) are cut out of flat materials on site to make thermal insulation outer protection. The basic principles are similar to sheet metal, and professional sheet metal workers can provide guidance.
, air ducts and air duct accessories
Circular air ducts are prefabricated and installed according to the pipe installation method with professional composite insulation exterior materials.
Square air duct straight pipe According to the outer dimensions of the air duct after being wrapped with insulation, fold the four sides of the prefabricated professional composite insulation outer protection plate with a special folding device. The overlap should be at the edge of the horizontal square air duct. The upper edge or the inner edge of the vertical square air duct (the side that does not affect the appearance) should have an overlapping width, and the overlapping seam should be sealed and solid with glue. When bonding, you can use ropes to temporarily fix it or multiple people to apply glue to the outer shell at the same time. The bottom of the horizontal square air duct is made of thermal insulation material and prefabricated professional composite thermal insulation outer protective material and is evenly dotted with glue.
The square air duct accessories are cut out on-site with prefabricated professional composite thermal insulation outer protection plates according to the outer dimensions of the accessories after they are wrapped with insulation. The overlap width should be appropriate, and the edges can be folded with a folding device. Minimize overlapping seams. The overlapping seams are sealed with glue. When bonding, you can use ropes to temporarily fix it or multiple people to assist in applying glue to the outer shell at the same time. The basic principles are similar to sheet metal, and professional sheet metal workers can provide guidance. The on-site production of prefabricated professional composite thermal insulation exterior materials is very convenient, and is much more convenient and beautiful than metal sheet metal.
Other precautions
The seams can be filled with white weather-resistant silica gel (it is recommended to use Tao Corning white mildew-resistant and weather-resistant silica gel, acidic). Pay attention to neatness and beauty.
When the glue does not require regular maintenance and has strict sealing, dustproof, and waterproof requirements, special glue should be used for sealing. Be careful not to use too much glue, do not use a small brush to apply the glue, use a small catheter with a thin thread to hang the glue. Note that if the glue sticks to your hands, just use a rough object such as sandpaper to remove it.
When disassembly and regular maintenance of threaded nails are required, after the overlapping parts of the professional composite outer protective materials are aligned, plastic self-tapping screws with threads can be used to fix them, that is, use a small Phillips screwdriver to first guide the holes and then tighten them. Just put it in, it is rust-proof and corrosion-resistant, can be disassembled and reused, and is easy for maintenance. Can be combined with jump-dot glue or super sticky double-sided tape for stronger, more beautiful spacing.
Insulation materials can be selected according to the actual application needs of pipelines. Prefabricated professional composite insulation exterior materials do not limit the selection of insulation materials. Any kind of thermal insulation material (such as rubber and plastic, glass wool, rock wool, aluminum silicate, foamed glass, polyurethane, etc.) can be outsourced and prefabricated with professional composite thermal insulation exterior materials.
