Q:SC15 what does galvanized steel pipe look like?
Ordinary galvanized steel pipe, the outer diameter is 1.5 inches
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.
Q:Stainless steel tube, also known as why tube?
Use can be divided into oil well pipe (casing, tubing and drill pipe etc.), line pipe, boiler tube, mechanical structure, hydraulic prop pipe pipe, cylinder pipe, geological pipe, chemical pipe (high pressure fertilizer pipe, oil cracking tube) and shipbuilding pipe etc.
Q:What is an electric welded pipe (EFW)? Seek help!
It is through one or several consumable between the electrode and the workpiece on the metal heating the metal between a process with the arc to metal and filler material fully melted, no pressure, filler metal parts work from all electrodes
Q:Where is the difference between seamless steel pipe and welded pipe?
Seamless pipe pressure is higher, welded pipe is generally in 10 or so MPa, now welded pipe to do seamless processing.
Q:How to make the steel pipe spray paint is not easy to fall off?
You're not usually advised to do it yourself, because you can't do it yourself. General powder coating, spray before the treatment is very strict, to be high temperature baking, and their spraying are dry paint, it does not add hardening agent, that is, the surface dry, but not hard, not wear-resistant. So don't scrape off the paint, or you'll look good after spraying, and it will be ugly in a few days,.If you really like to look good, you can buy some stickers back to paste, without affecting the appearance..
Q:Is the diameter of the steel tube indicated by the outer diameter by the wall thickness or by the inside diameter by the wall thickness?
For seamless steel pipes or nonferrous metal pipes, the outer diameter * wall thickness shall be marked".For example, 108 x 4 phi, Phi can be omitted. Some steel tubes in China, ISO and Japan adopt wall thickness to indicate the thickness of steel pipe. The method for the specification of such steel tubes is pipe outer diameter * wall thickness. For example, Phi 60.5 * 3.8.
Q:Can stainless steel pipes spray black paint?
Can. The surface roughening with a thick gauze, do not use ordinary paint intensity difference. With resin paint, paint can be
Q:What does "HBB" glass steel pipe mean?
The utility model has the advantages of high strength, light weight, no deformation, smoothness of the inner surface, etc.. The friction coefficient is small, the cable is light and smooth, and the cable is not damaged. The weight is only 1/4 of the steel tube, and the 1/10 of the concrete pipe can be moved by one person. The transportation is convenient and the construction is simple and convenient.
Q:What type of steel pipe for security windows?
25 parties, 70 parties in general! Good point of about 90; 25/38 general 90, a good point of about 120! The model is usually 202. If 304 is used, it is usually multiplied by 2! Plastic steel window material is hard plastic! Inside a single glass lined steel prices have 75/90/120/150/ different brand price this is the price of the window! Aluminum alloy is generally 100/120/150/175/190 area, different prices different
