Q:Why does the air conditioner outdoor pipe joint freeze and freeze in case of refrigeration?
Fluorine slightly more: thick pipe icing or frost, because the refrigerant inside the machine is not completely vaporized, back to the end is still vaporized heat absorption.Excessive dust in the inner filter screen or evaporator: the internal air circulation is not smooth, resulting in the backflow of the subcooled refrigerant, the icing of the thick pipe, and the cooling effect.
Q:Hot tap water pipe joint leakage, what method can be repaired?
The original hot connection place cut, a new joint with a pipe section, and then pick up
Q:What kind of tubing connections do you have?.
Pipe joint is detachable between the tubing and tubing, tubing and hydraulic components of the connection, it should satisfy the convenient assembly and disassembly, reliable connection, reliable sealing, small size, large capacity oil, small pressure loss, good processing etc.
Q:The name of the card sleeve joint
One is a card sleeve, the other is a threaded sleeve type joint called a sleeve type end angle pipe joint (wherein, the clamping sleeve is an end right angle pipe joint and a sleeve type taper thread end right angle pipe joint)
Q:About thread, pipe joint standard question
For thread purposes, you are recommended to study the metric, American and American thread standards manual
Q:What are the standards for the pipe connections at both ends of the cone pipe?
A spiral shaped continuous raised part having a specified cross section on the surface of a cylinder or cone. According to its parent thread shape is divided into cylindrical and conical screw threads; according to their position in the matrix is divided into outer and inner thread, according to the section shape (teeth) divided into triangular thread, rectangular screw, trapezoidal thread, serrated thread and other special shape screw.
Q:Type parameter of pipe joint

Q:Drawing design, drain cross dry pipe is flexible cast iron pipe, vertical pipe is PVC pipe joint
But in actual construction, because the special AD type bottom joint is more expensive, the construction unit usually adopts the cast iron pipe elbow to deal with the problem of reducing the diameter of the two kinds of materials.
Q:What is the nominal diameter of the phi 1/2 in the pipe joint?
1/4, 1/2, 1/8 is the nominal diameter of inch inch, inch in inches1/2 inches, usually read as "four thiophene"".
Q:Puvc pipe joint leakage how to do?
Common leakage of different types of water pipes1, water pipe leakage reason: this situation generally belongs to relatively minor, it is not difficult to solve, it is because the water pipe and faucet did not connect well.2, the leakage of water pipe: water pipe hardening or long time foreign matter blocked the water pipe, resulting in rupture.
Our company has integrated equipment and processing capacities of machining, heat-treatment, surface treatment, and hot extruding. For human resources, we have 16 senior engineers, 16 engineers and technicians and 14 inspectors, and have advanced processing technology and experience in casing and tubing couplings, pup joints, tool joints and down hole tools.
