Q:G1/8 "pipe joint end special sealing WD-B02 is what mean
The sealing effect is better than the traditional O ring. The elastomeric seals are used as axial static seals for threaded oil and screw ends, and the cross section remains almost constant at high pressure.
Q:Connect with stainless steel tube with 304 stainless steel clip type pipe joint,
I personally think that the installation problem, that is, the card sleeve and steel pipe only after installation to reach the sealing effect, the installation quality can not meet the design pressure requirements.To avoid this situation, it is recommended that after installation 1.25 times higher than the design pressure test, test pressure can be put into use
Q:Is the joint of ground heating pipe and aluminium plastic pipe general?
The floor heating pipe is usually PE-RT, and the plastic layer of the aluminum plastic pipe is usually PPR or PE-X. Generally speaking, different materials are best not to be mixed.
Q:Can the pressure vessel pipe joint adopt G thread? Why?
1 、 pressure vessel pipe joints do not use G thread, because G thread is not sealed enough.
Q:How was the pipe joint named?
Use the end extension of the pipe for sealing without any other seals. The utility model has simple structure and is suitable for the connection of thin-wall pipe fittings, and is suitable for pipelines with low pressure of oil and gas as medium. The pressure is allowed to be used in table 41, table 27~41, GB5625.1 to 5653-1985Insert welded pipe jointThe length of the tube will need to be inserted into the pipe joints and pipe end until the connector end of the contact, the pipe and the pipe joint are welded together, can save over, but the pipe size is strictly applicable to oil and gas as the medium pipeline system table 43 ~ 49 JB3878-1985Cone seal welded pipe jointOne end of the connecting pipe is provided with an outer cone surface, and a O shape sealing ring is matched with the inner cone surface of the joint body, and is screwed with the screw thread. The working pressure is 16 ~ 31.5MPa, the temperature - 25 to 80 DEG C for oil as medium piping system table 50 ~ 62 JB/T6381 ~ 6385-1992Withhold hose connectorThe installation is convenient, but a tightening process is added. After the hose is damaged, the joint coat can not be reused, and it is made up of a steel wire braided hose. The utility model can be connected with a welding pipe joint sealed with a O ring. Pipeline system suitable for oil, water and gas as medium. Medium temperature: Oil: -30 ~ 80 degrees Celsius; air -30 to 50 degrees Celsius; water below 80 degrees JB/ZQ4427 ~ 4428-1986
Q:Screw in pipe joint Dg10 what do you mean?
The diameter of the pipe can be divided into outer diameter, inner diameter and nominal diameter.The pipe is a seamless steel pipe pipe diameter by the letter D to represent, then additional outer diameter size and thickness, such as diameter of seamless steel pipe 108, a wall thickness of 5MM, denoted by D108*5, is also used outside said, such as De63 plastic pipe, such as reinforced concrete pipe, cast iron pipe, galvanized steel pipe, said the DN, in the design drawings is generally used to represent the nominal diameter, nominal diameter is a standard in order to design and manufacture and maintenance convenient set artificially, with nominal diameter, tube (or pipe) specification name. The nominal diameter of a pipe is not the same as the inside diameter and the outside diameter of the pipe,
Q:What does R1/2 pipe joint mean?
Engineering diameter comparison table (commonly used)1 inches =25.4 mm =8 British cents1/2 is four points (4 English points) DN153/4 is six points (6 English points) DN202 in charge of DN84 in charge of DN156 in charge of DN201 'DN251.2 'DN321.5 'DN402 'DN502.5 'DN653 'DN804 'DN100
