Q:The union bonnet (Union Bonnet) and bolted bonnet valves (Bolted Bonnet) the same?
Dissimilarity:The union bonnet (Union Bonnet): it is with the cap (pipe joint) direct pressure filler
Q:Does the American and English fittings how to recognize it?
What's the amount of taper thread you want? This is really a bad amount. Taper pipe threads are specified: within the range of the effective thread length, there is any place that meets the requirements (as you say, NPT1/2), because the pipe threads are sealed with little depth. Only a few teeth used for sealing, but the thread specification according to the requirements, for example, you say NPT1/2-14, then the pitch is 1/14 inches, in addition, the effective thread in a certain position must be the nominal diameter of 1/2 inch. I don't know, I said so, you know, no, no, I don't have a good idea for you, but I'm sure I didn't cheat you. I'm doing this, not an expert, but it's my business, huh?.
Q:What are the types of tubing and pipe couplings applicable to each occasion?
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.. According to connection tubing and pipe joints, pipe joints are welded, sleeve type, expanding type, press type form; pipe joints each form, according to the channel number and direction of joint points straight, rectangular, three other types; threaded connection and flange connection with the connection of the body. In addition, there are some special purpose pipe couplings.
Q:What's the difference between the half pipe joint and the branch seat?
The main body of the branch pipe is made of high quality forgings. The material is the same as the pipe material. Carbon steel, alloy steel, stainless steel and so on. The branch pipe and the head adopts a welding, pipe seat and branch pipe or other pipe (such as tube plug, etc.), instruments and valves connected with butt welding, socket welding, threaded types.
Q:Can the pressure vessel pipe joint adopt G thread? Why?
3, pressure vessel, English: pressure vessel, refers to contain gas or liquid, carrying certain pressure airtight equipment
Q:PT1/4 large diameter pipe joint? No figure urgently
The thread has a taper of 1:16, equivalent to 55 degrees taper pipe thread, or ZG
Q:What are the specifications and models of hydraulic pipe fittings?
The connection forms of the pipe joint include thread, welding and clamping sleeve, and the shape of the pipe joint is straight through and elbow
Q:What is the manual pre assembly procedure for the EO-2 joint?
I. pre assembled1, EMB card sleeve type pipe joint pre assembly of the most important link, directly affect the sealing reliability. A dedicated preprocessor is usually required. The small diameter can be pre joint in a vise. The concrete method is to use a joint as the mother's body and press the nut and the sleeve onto the tube. The utility model mainly comprises a sleeve type through pipe joint, a clamping sleeve type end through connection head, a clamping sleeve type three way pipe joint and other patterns. I found that even if the same manufacturer of a batch of goods, the cone of these joints on the depth of the hole is often different, resulting in a leak, and this problem is often neglected. The correct approach is to connect the end of the pipe with what kind of joint, and the corresponding connection ends are prefabricated with the same type of joint, so that the leakage problem can be avoided to the maximum extent.
Q:The material is 304 stainless steel 1/4 "NPT" threaded joint. How much MPa pressure can be received?
The twenty-first page specifies the level of thread and material corresponding to the pressure application. Stainless steel thread used in the steam is 7 kg pressure (bar), the water temperature is above 105 degrees celsius. Other restrictions, standards.
Q:What is a slot type mechanical joint?Copy search
The groove connecting pipe consists of two categories of products: sealing function of pipe connections with rigid joint, flexible joint, mechanical three and groove flange; the pipe connections transition of elbow, three links, four links, different diameter pipe, blind plate etc..
