General introduction

 

Polyethylene sleeving is a tubular film of low density polyethylene slipped over and snugly to a pipe at the time of laying. It is used to supplement the basic pipe coating (metallic zinc + bituminous paint) in certain cases of highly corrosive soils, or in the presence of stray currents. Standards: EN 545, ISO8180.

Q:Very confused about the pipe fittings and the fittings, and can not distinguish them
The task is accomplished by the joint body, one end of which is connected to the pipe joint and the other end connected to the device
Q:What are the types of hydraulic couplings?
Mechanical design manual fourth volumes, hydraulic pipe joints are there?. You go check it out,.
Q:What is the taper angle of flared tubular joints?
With the pipe after welding, has the characteristics of reliable connection, good sealing performance, so it is widely used in oil refining, chemical industry, light industry, textile, metallurgy, national defense, aviation, shipbuilding and other systems; also suitable for hydraulic transmission of various mechanical engineering, machine tools and other equipment pipeline.
Q:What is a reinforced pipe joint?
It has a certain mechanical strength and good shock absorption. It is suitable for making parts under moderate stress, working parts in weak corrosive environment, such as cover, bearing seat, valve body, hand wheel and so onThe main purpose of strengthening the pipe joint is to connect, install and maintain conveniently.
Q:What does flaring pipe joint mean?
Head with taper, 2 face taper rigid seal, generally have 60 degrees, 74 degrees, 24 degrees, 90 degrees these
Q:Pipe joint thread, said in 2 / 3 / 4 points, what does that mean, how to convert ah?,
2 points =2/8, that is, 1/4 inches, and the others are divided by 81 inches =25.4 mmIf it means the thickness of the pipe, it is the British tube of 1/4Indicates that the thread size is the thread of G 1/4
Q:What is the nominal diameter of the phi 1/2 in the pipe joint?
1 inches =25.4mm.1/2 "- 4 thiophene, 3/4" - 6 thiophene, etc..Pipe, pipe thread and machining are often used in these old units, but they are not legal units of measurement in our country.Installation industry and business are commonly used in this unit.
Q:What does national standard joint jb/t6381.2-92 mean?
Apply to oil, gas as medium, pipe system in the cone sealing welded straight through 55 degrees non sealing pipe thread pipe joint. Nominal pressure PN is less than or equal to 31.5MPa, the working temperature of -25 DEG ~+80 deg.
Q:The pipe connections have different diameters. Reducing the diameter, what else?,
If there is no change in diameter: different diameter (that is, variable diameter) joints and the same diameter joints
Q:How tight is the gas pipe joint?
For a fixed gas pipeline, it should be installed by a professional Gas Co, and the individual shall not change the sealing of the joint. It should be sealed by special sealant. Plastic pipes should not be too long, should be far away from the electrical circuit, and the high temperature area of the hearth.
