Q:How do you explain the pipe joint?
For example, a 4 point tube is 1/2 inches, and this size represents the diameter of the inner hole, that is, the passing diameter of the fluid.
Q:What is the difference between the pipe and the pipe joint?
A metal tube 1, ordinary carbon steel wire (wire casing pipe) 2, metal flexible pipe (galvanized pipe, stainless steel pipe, plastic coated metal snakeskin snakeskin tube)
Q:How do you disconnect the PVC pipe joint that has been glued?
A sticky PVC pipe joint is not normally open. Only cut off and re connect.Do you know?
Q:What is the size of the PVC pipe joint?
[1] the PVC joint size is in inches, 1 inches =25.4 millimeters.[2] PVC: polyvinyl chloride (English: PolyVinyl Chloride abbreviation: PVC) is a use of a chlorine atom to replace one of the hydrogen atoms in polyethylene polymer material. PVC is an amorphous white powder with less degree of branching
Q:What are the materials for fire hose fittings and connections? Can I use stainless steel 316?,
Material is pig iron castings. Stainless steel can be used.A fire pipe is a pipe material used for fire fighting, fire fighting equipment, equipment, fire fighting water, gas or other medium.As the fire pipe is often in the static state, and therefore more stringent requirements of the pipeline, the pipeline needs pressure, corrosion resistance, high temperature performance.
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.
Q:What are the sealing ways of pipe joints? Thank you
PTFE raw tape. Sealant。 If it is steel and copper inside and outside the thread, as long as the tightening, what sealing material can be used.
Q:What are the reducing, reducing, reducing, etc in the pipe joint?
Do not know where you see these pipe joint nouns, you should say are all variable diameter pipe joints.
Q:PT3/4 what is the diameter of the pipe joint?
1. thread sealed pipe threads, without padding or sealing, can prevent leakage. The pipe thread with screw thread has two connecting forms: cylindrical internal thread and tapered outer thread, tapered inner thread and tapered outer thread. When the pressure is below 5 * 105Pa, the former connection is close enough, and the latter connection is usually used only at high temperature and high pressure.
Q:What are the differences between hydraulic couplings and fittings and elbows?
Connector: when the pipe joint and the equipment are connected, the connection mode does not match or needs to be changed, and the task is finished by the connector body. One end of the joint body is connected with the pipe joint, and one end is connected with the equipment.
