Galvanized steel pipe dn25
Galvanized steel pipe dn25 had a nominal inner diameter of 25 mm and an outer diameter of 33.7 mm. It was a 1-inch pipe, which corresponded to 8 pipes, because 1 inch was equal to 8 minutes and its diameter was generally 25mm (1 inch). In the application of fire sprinkling pipe, fire faucet pipe, etc., according to the specifications of GB50084 - 2017, the minimum end should not be less than the diameter of the pipe. The diameter of the pipe should not be less than the diameter of the pipe, and the diameter of the pipe should be less than the diameter of the pipe. The thickness of the pipe wall can be changed by 10% according to the standard of the national standard of the national standard, and the weight per meter is about 2.57kg. However, due to the difference in wall thickness and processing precision, the weight may change. After adding 10% of the margin, the weight per meter is about 2.8kg.

Galvanized C steel theoretical weight table, specifications table
The following is the theoretical weight table of some of the Galvanized C-steel: - C80 steel: cross section 80mm × 40mm, thickness 5mm, weight 0.4kg/m. - C100 steel: 100mm × 50mm, 5mm thick, 3kg/m weight. - C120 steel: 120mm×53mm in cross section, 5mm in thickness, and 1.4 kg/m in weight. - C140 steel: 140mm × 58mm, 0mm thick, 1.9kg/m. There were also 80x40x1.5x0, 100x50x1.5x5, and so on. For example, the 80x40x1.5x0 specifications had a cross-section height of 250mm, a cross-section width of 80mm, a curling width of 20mm, and a thickness of 0mm. It was suitable for building structures, rail transit, power transmission lines, and other fields. It could be used for supports, beams, columns, and other components. The specifications of C-type steel are usually expressed in the form of C80x40x20x5, where C80x40x20x5 means that the cross-section height H = 80mm, the cross-section width B = 40mm, the curling width C = 20mm, and the thickness t = 5mm. C-type steel bars were divided into five specifications according to their height: 80, 100, 120, 140, and 160. The theoretical weight of C-type steel was not convenient to calculate with a formula. The formula was: weight in meters = volume in one meter x density of steel. It was recommended to check the table. The novel "Watching the Moon on Fish Island" is equally exciting.

The horizontal drainage pipe is connected with the horizontal pipe
The horizontal drainage pipes shall be connected with the horizontal drainage pipes by oblique three-way, oblique four-way or three-way and four-way along the water. To be specific, the connection between the horizontal sewage pipes should not be made with a straight three-way or a straight four-way, but with an inclined three-way or an inclined four-way or a straight three-way or a straight four-way. These connections could ensure the normal operation and drainage effect of the drainage pipeline.
The difference between the main pipe and the branch pipe
The main pipe, main pipe, and branch pipe had different definition and functions in the water supply system. The following conclusions: The main pipe referred to the pipe section from the indoor main valve (or water meter) to the water supply standpipe. It was usually in the form of a standpipe, responsible for guiding water from the water source to various locations in the building. The main water supply line was usually the main water supply line in the system and could span multiple floors. The main pipe referred to the pipe section from the water source to the most unfavorable point. The most unfavorable point could be the farthest water distribution point or the highest water distribution point. The main pipe was usually in the form of a vertical pipe or a horizontal pipe, because it must have small pipes that were divided from other pipes. These small pipes were branch pipes. The function of the main pipe was to connect the pipe section of the household pipe and the branch pipe to carry out up and down transportation. The branch pipe was a water distribution pipe on the same floor, starting from the main pipe and ending at the water distribution valve of the faucet or sanitary ware. The branch pipe was usually a horizontal pipe that connected to sanitary ware or other water points. In summary, the main pipe, the main pipe, and the branch pipe have different meanings and functions in the water supply system. The main pipe was the main water supply line, the main pipe was the pipe section that connected the household pipe and the branch pipe to transport water up and down, and the branch pipe was the water distribution pipe on the same floor.
What makes galvanized horror stories so chilling?
The cold, metallic look of galvanized objects. It gives an impression of something industrial and soulless. For example, in a horror story, a galvanized cell in an abandoned prison can be a very creepy setting. It's not like a warm, wooden room. The shiny, yet dull - looking galvanized walls seem to hold secrets.
Can you share some galvanized horror stories?
One galvanized horror story could be about an old, abandoned galvanized factory. People say at night, strange noises come from it. The creaking of the rusty machinery and the echoing of footsteps in the empty halls. Once, a hiker got lost near it and when he peeked through a broken window, he saw a shadowy figure moving among the old galvanized vats, as if something was still alive in that long - dead place.
Horizontal branch pipe and horizontal main pipe of drainage
Horizontal branch pipes and horizontal main pipes were two types of pipes in the drainage system of buildings. The horizontal branch pipe was a horizontal pipe section connecting the sewage collection device drain pipe and the vertical drainage pipe, and was used to send sewage from the sewage collection devices to the vertical drainage pipe. The horizontal branch pipe should have a certain slope to facilitate smooth drainage. The horizontal main pipe was a pipe section that connected several drainage vertical pipes to the discharge pipe, mainly to receive the drainage of the horizontal branch pipe. The connection point of the horizontal branch pipe and the horizontal main pipe has a certain distance from the bottom of the vertical drainage pipe to ensure the normal operation of the drainage system. The specific connection requirements could refer to the relevant specifications and design standards.
The difference between upvee spiral pipe and drainage pipe
The difference between the UpPVP spiral pipe and the drainage pipe was that the UpPVP spiral pipe was a special type of drainage pipe with a noise reduction function. The inner wall was smooth, and the noise during drainage was low. The drainage pipe was an ordinary pipe with no noise reduction function. Therefore, the upvee spiral pipe could reduce noise during the drainage process, but the drainage pipe did not have this function.
Is the horizontal branch pipe the same as the horizontal main pipe?
The horizontal branch drainage pipe was different from the horizontal main drainage pipe. The horizontal branch pipe was a horizontal pipe with a water point, while the horizontal main pipe did not have a water point and only had a branch pipe.
The drainage horizontal branch pipe is connected with the vertical pipe.
When the horizontal drainage branch pipe is connected to the vertical pipe, different connection methods can be used. According to the Design Standard for Building Water and Waste Water, when the sanitary ware drainage pipe is vertically connected to the horizontal drainage pipe, a 90° inclined tee should be used. When the horizontal branch pipe is connected with the vertical pipe, it can adopt a three-way or four-way downstream pipe and a 45° inclined three-way or 45° inclined four-way pipe. In a special single-standpipe system, the horizontal branch pipe and the standpipe can be connected by special accessories. In addition, according to some provisions of the Building Water and Waste Design Code, when the drainage stand pipe is only equipped with a top vent pipe, the vertical distance between the lowest drainage horizontal branch pipe and the stand pipe bottom shall not be less than the specified distance. According to the Connection Design and Material Selection of Building Drainpipe Branch and Horizontal Main, when the drainage branch pipe on the upper layer of the horizontal main drainage pipe is connected to the horizontal main drainage pipe, it is recommended to use a 45° inclined tee to connect it from the top of the horizontal main drainage pipe. To sum up, when the horizontal drainage branch pipe is connected to the vertical pipe, different connection methods such as 90° inclined three-way, downstream three-way or downstream four-way, 45° inclined three-way or 45° inclined four-way can be used.
