Q:Man, can you send me some national standards? Mainly for hydraulic use
Domestic standards, I do not have any standards, the domestic standards of learning German, learn from other countries standards, do very badly.SN standard pipe taper angle of 24 degrees and 30 degrees in China, can not mix.
Q:New standard, how can the pipe joint be labeled, such as "3/4" taper pipe thread?
60 degrees taper pipe thread: NPT3/4"55 "taper pipe threads: external thread -R3/4", internal thread -Rc3/4"
Q:Silicone gasket, rubber gasket, water pipe joint which is good?
More suitable for food grade high water pipe, especially high temperature resistance, high temperature water pipe is best to use silica gel gasket
Q:Hydraulic pipe fittings, DIN, GB, American Standard how to distinguish?
PT is the abbreviation of Thread Pipe, is a 55 degree taper pipe thread sealing, belonging to the Whitworth family, for the European and Commonwealth countries. Commonly used in water and gas pipe industry, taper regulations of 1:16. national standard is available on the GB/T7306-2000 G is 55 degrees non thread sealing pipe thread, a thread labeled Wyeth family. As the representative of G cylinder thread. The national standard is available on the GB/T7307-2001 thread in 1/4, 1/2 in addition, 1/8 marker refers to thread size diameter, unit is inches. Insiders usually used to call thread size, one inch 1/4 inch is equal to 8 points, 2 points, and so on.G seems to be referred to as pipe thread (Guan), 55, division 60 degrees are functional, commonly known as the tube. The thread is machined from a cylindrical surface.

Q:Why have speed bumps gotten bigger in recent years?
put some chese on it
Q:110 degree PVC pipe joint
The PVC pipe can be changed from two to three elbows, and try more than 45,35 meters of pipe can be installed according to the slope of 1%, the specific depends on the situation, if the flow is larger, but also with construction conditions, it is recommended that the slope is a little larger.
Q:The pipe line of the hydraulic pressure pipe is formally installed
Hydraulic pipe fittings - thread standard twoClassification of threadsThe 1. threaded internal and external threads two;2. according to the shape of teeth can be divided into: 1) triangular thread 2) trapezoidal thread 3) rectangular thread 4) sawtooth thread;3. by line, single, head and multi thread;4., according to the direction of rotation, two kinds of left and right threads, the right is not marked, left plus LH, such as M24 * 1.5LH;5. according to different uses are: metric common thread, thread sealed pipe thread, non threaded sealing pipe thread, 60 degrees taper pipe thread, metric taper thread, etc.Two. Metric general threads1. metric screw thread with a capital M, tooth type angle 2 degrees =60 (alpha tooth type half angle);2. metric ordinary thread by pitch, coarse teeth, ordinary thread and fine teeth, two kinds of ordinary thread;2.1. coarse tooth ordinary thread mark generally does not indicate the pitch, such as M20 means coarse thread; fine tooth thread mark must indicate the pitch, such as M30 * 1.5 for fine tooth thread, in which pitch is 1.5.
