Q:What does flaring pipe joint mean?
The joint is tapered and the pipe is straight, which requires the use of special tools to extend the end of the pipe to the bell mouth
Q:Do you have DN150-DN80 variable diameter steel pipe joint?
Do you have DN150-DN80 variable diameter steel pipe joint? Is there a standard in this respect?What's his length, L? Look at the picture
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:What is the difference between a D-LD2000 clamp type flexible pipe joint and a KRJ clamp flexible pipe joint?
Four, flexible pipe joint internal structure and KRJ internal structure is slightly different, flexible pipe joint no retreat or small platform, and the latter is large return platformFive, flexible pipe joints, standard clamp type flexible pipe joints, disassembly can be worn down, shoulder type flexible pipe joints can not be.Note: some units in the market now confuse the two products with the aim of selling high priced products at lower prices so that they can make more profit margins. To ask for the data parameters of the drawing, to judge whether it is a flexible pipe joint or a flexible pipe joint.
Q:Hydraulic jointWho knows the hydraulic connection "3/8*25.4=9.525" refers to the connection?
3/8 is an English name. We call it "10 connectors", referring to the outer diameter of this joint.
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 are the specifications and models of hydraulic pipe fittings?
Three way, variable diameter, etc.. Specifications, models, tens of thousands. You want someone to make it clear to you that the joke isn't fun.
Q:What is pressing type pipe joint
If necessary, I will send you the connector type and specifications
Q:Hydraulic hose joint is spherical and cone sealing, threaded connection, what is the form of joint?
WREN we also do ultra high pressure joint (hydraulic joint) and all hydraulic wrenches, hydraulic pumps, etc., you can contact us to negotiate!
Q:Standard Specification for jacket type pipe couplings for card sleeve couplings
Britain said the outer diameter and thickness of MM 10 1/4 10 "" 1/4 "" 1/2 12 "12.76 * 1.6012 (13) 3/8" "3/8 12" 17 * 2.25 "3/8 15" 15.87 * 1.6015 (16) 1/2 "" 1/2 15 "21.25 * 2.75" 20 3/4 19.05 "x 1.6020" (19) 3/4 "20 3/4 26.75" x 2.75 "251" 25.40 x 1.80251 ""
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.
