Q:Requirements for fire hose fittings
Main technical points of connection of fire water supply pipe4.3.1 General requirements(1) welding shall not be used when using hot galvanized steel pipes inside and outside the fire hydrant water supply system. The system pipe adopts the inner wall without corrosion, and the pipeline can be welded and connected, but the welding of the pipeline shall comply with the relevant requirements. Automatic sprinkler system (alarm valve), the pipe can not be welded, should be threaded, groove, pipe or flange connection.
Q:PT1/4 large diameter pipe joint? No figure urgently
The basic size of large diameter pitch thread code P per inch TPI in diameter of external thread tooth type D3 path height H1 bottom hole sizeG, 1/4, 1/4, 13.157, 1.33719, 12.301, 11.445, 0.856, 11.6
Q:What are the connecting forms of industrial pipe joints? Like buckling type connection,
The quick joint is a pipe joint which needs no tools and can be quickly disassembled and assembled. It has the advantages of compact structure, small size, light weight, high pressure resistance and interchangeability
Q:Hydraulic pipe fittings, DIN, GB, American Standard how to distinguish?
ZG is a commonly known as cone, cone thread processing, pipe joint is generally the old GB marked Rc for metric threads to represent the thread pitch, with every inch of the thread number, this is the biggest difference between them, metric thread is 60 degrees equilateral tooth type. 55 inch thread is isosceles tooth type of thread, 60 degrees. Metric units for metric threads; British and American systems. Pipe thread is mainly used for pipe connection, the internal and external threads are closely matched with straight pipe and cone pipe two kinds. Nominal diameter refers to the diameter of the pipe to be connected. Obviously, the diameter of the thread is larger than the nominal diameter. 1/4, 1/2, 1/8 is the nominal diameter of inch inch, inch in inches.
Q:Apart from the air-conditioning, the high-pressure pipe is not tight enough. What shall I do?
The position of the station is wrong, the output is not working / the spanner angle is not right... The most simple, is to find a major wrench with a long handle and then force that, if the screw is not open, it may break pipe head, we should pay more attention to the....
Q:What's the difference between pipe repair device and clamp type flexible pipe joint?
The clamp type flexible pipe joint needs welding, but the pressure range is big, 10-220 kilograms of pressure can bear, and it has the limit function, at the same time provides the effective flexibility and the corner to the limit. The utility model is generally used on pipelines of more than 16 kilograms, and the cost is greatly lower than the flanges and the telescopic devices.
Q:Type parameter of pipe joint

Q:How to choose the connection mode of clamp type flexible pipe joint correctly
The overall price of steel ring is lower than that of pipe endSummary: the middle and high pressure pipeline is recommended to use the pipe end connection, and the middle and low pressure pipeline is recommended to use the steel ring connectionThe customer can choose the clamp type flexible pipe joint (steel ring joint) or clamp flexible pipe joint (pipe end connection) according to the demand to reduce the purchasing cost.
Q:What's the hydraulic pipe joint material?
Chemical equipment piping usually walks a variety of corrosive fluids, the need for frequent use of solvent or water rinse. Therefore, the general chemical line must be stainless steel.While thinking about medium corrosion. We should consider the relation between pipe seal and medium. Ding Qing rubber is commonly used in hydraulic systems because it is miscible with ordinary hydraulic oils. Ding Qing rubber at a certain temperature, but also with the synthesis of acetaldehyde, sugar chemical liquid (HEPG) and the proposed plant in liquid and compatibility, nitrile rubber (NBR) is not suitable under high temperature and acidic medium, benzene or synthetic oil, then should use fluorine rubber (FKM), on the contrary, methane and refrigeration only with ammonia NBR (NBR) miscible, so most chemical stainless steel pipeline are rigid seal.
Q:What does pipe joint "DD" mean?
Parts that work in a weak corrosive environment, such as covers, bearings, valves, hand wheels, etc., are joined mainly for connection, installation and maintenance.
