Q:How can galvanized steel pipe be connected with stainless steel pipe?
Attention should be paid to the zinc coating at the side of the groove before welding. It is OK to brush silver powder after welding. There is a lot of information about the welding of carbon steel and stainless steel. Just check it online.
Q:What does "buried steel pipe" 6*2SC100 mean?
Welded steel pipe refers to the use of steel or steel plate bending deformation into a round, square and other shapes after welding into the surface of the joint of the steel pipe. The blank used in welded steel pipe is steel or strip steel.
Q:Will the steel tube dance?
Pole dancer performing double pole dance performance is much higher than single pole dancing difficult, because not only refers to the double pole dance together the two pole dance, two people should pay attention to the dance and tube movement, if two people do not fit to dance moves and skills on the tube action, you jump you. I jump, that wasn't a real double pole dance, dance like a double tube. If the two dance movements and pipe movements are not good enough or not natural enough, they will destroy the effect of the whole dance and make the audience feel that the dance is chaotic and not beautiful, so it is better to see a single pole dance. But the dancer's double pole dance performance is good, more powerful than single pole dance, and more aesthetic and artistic.
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:Galvanized steel pipe in addition to good rust resistance, what are the advantages?
Because the zinc has been plated outside the steel tube, the time for oiling or painting outside is omitted, and the construction is more convenient;
Q:Are galvanized steel tubes the same as degaussing steel tubes?
Also known as galvanized steel pipe, hot galvanized and galvanized two kinds, hot galvanized, zinc coating thickness, with uniform coating, adhesion, and long service life. The cost of galvanizing is low, the surface is not very smooth, and the corrosion resistance of itself is much worse than that of galvanized pipe.
Q:Theoretical weight of 25*25*1.5 square steel tubes
Square steel tube, referred to as square tube, also known as square tube, is a square pipe of a kind of name, that is, the length of the same steel pipe. The strip is rolled by process. Generally, the strip is disassembled, leveled, crimped and welded to form a round tube. The tube is then rolled into square tubes and cut to the required length, usually 50 pieces per package.
Q:How long is the seamless tube?
Generally finished seamless steel tubes are less than twelve meters, mainly for the convenience of shipment.In times of rolling (processing), the steel pipe can reach 80 meters or longer.
Q:Seamless steel pipe 8162 and 8163 what is the difference?
8163 GB is fluid delivery tube, need to use eddy current detection, fluid transport, liquid, gas, solid, such as natural gas, water, gas, coal and stone, 8162 and 8163 of the popular point that is 8163 more than 8162 senior, 8163 inspection, 8162 inspection. I hope you understand!
Q:How can the immersed pipe pile put steel cage into the steel pipe? Which expert to answer?
Immersed tube cast-in-place pile is one of the many types of pile foundations in civil engineering. The immersed tube cast-in-place pile is also called the cast-in-place pile. It is the use of piling equipment, with reinforced concrete pile boots (valve type steel pipe pile shoe) into the soil, pile hole, and then put into the steel skeleton and concrete pouring, then pull out the casing, using vibration extubation of concrete compaction, forming pile needed. Using hammer sinking pile equipment, sinking pipe and pulling pipe pile is called hammer sinking pipe filling pile. It is called vibro sinking pipe cast-in-place pile by vibrator, vibration sinking pipe and pipe pulling pile. In order to improve the quality and carrying capacity of piles, the construction techniques of single shot, double play and reverse insertion are often used in immersed tube cast-in-place piles. Single game (also called a extubation): extubation, every increase of 0.5 ~ 1.0m, 5 ~ 10s vibration, then extubation in 0.5 ~ 1.0m, this is repeated until all pull out; complex play: two singles were continuously in the same pile hole, or according to the needs of the local retapping. Construction, should ensure that two times before and after the immersed tube axis coincide, and in the concrete before the initial coagulation; inverted plug method: steel pipe lifting 0.5m, and then plug 0.3m, so repeated until the pull out.
