Krhd steel flexible joint is also called split expansion joint and steel flexible joint. Steel flexible pipe joint is a kind of pipe connection product with reliable performance and easy installation. At low pressure, the elastic deformation of the sealing ring is used to achieve the sealing purpose; when the pressure increases, the medium acts on the sealing ring to play the role of self sealing, and there is a gap between the pipe ends to compensate the displacement and deflection caused by thermal expansion and cold contraction of the pipeline.
KHD is a kind of flexible pipe joint, which is derived from the flexible ring and is a kind of flexible pipe joint. They cooperate with each other to form a flexible connection mode. It is suitable for pipeline with large compensation and complex terrain.

  • Quality stability: the implementation of the whole process of quality monitoring, meticulous, all-round detection!
  • Reasonable price: efficient internal cost control, reduce expenses, and benefit customers!

Product advantages

Krhd type steel flexible joint is of split structure, which is easy to install and dismantle without lifting equipment. It is installed on one side of the valve pipeline or at the inlet and outlet of the pump in the pump room, which is convenient for equipment installation, disassembly and maintenance, and can also be used to compensate the pipeline displacement and vibration isolation and noise reduction of the pump. Before the installation of krhd steel flexible pipe joint, loosen the pressure plate bolt, pull the product to the installation length, and then tighten it with diagonal method. Do not press off. If it is used overhead, the corresponding fixed support must be installed at both ends. Features of krhd type steel flexible pipe joint:
1. The installation speed is more than 3 times faster than that of flange connected pipe fittings.
2. It is lighter than the flange, the locking mechanism is ingenious, the number of bolts is less, and there is no need to lock the holes.
3. It is reliable. ① the clamp, washer and pipe end groove are compressed in the whole circumference, and the tensile strength of the pipe end is large, the test pressure is 4.2mpa, the temperature is - 30 ℃ - 100 ℃, and the vacuum degree can reach 0.08mpa; ② the gasket is designed as C type, which can form triple leak proof, and the greater the pressure in the pipe, the better the sealing; ③ the gasket can be properly selected according to the fluid medium, pipe material and temperature.
4. It can also absorb the vibration of the pipe and can absorb the vibration of the pipe.
5. It is economical, safe and convenient for project budget. It can save 20% of the total project cost compared with flange connection. There is no need of power supply, oxygen and open fire for construction.
6. Zero pollution because the original installation does not have welding slag and damage the zinc coating and plastic coating, it can ensure the smooth pipeline. The connected pipeline, especially the fire sprinkler system, will not rust and block the equipment and spray head in the pipeline due to other connection methods.
7. The space of flange installation is 3:2 than that of clamp joint. ② Clamp joint and accessories can be installed first, and can be adjusted in any direction, angle, piping at will.
8. It is easy to maintain, remove, wash and replace, just remove two clamps and four bolts, which is convenient for pipeline extension, replacement and rotation direction. Uniform wear.

Product features

Flexible pipe joints are divided into steel ring type and pipe end type. The difference between the two products lies in the installation mode and cost. The steel ring type flexible pipe joint is suitable for low-pressure pipeline and has strict welding requirements. The flexible pipe joint has a wide range of application, and can be used in high, medium and low pressure. The disadvantage is that the cost is slightly higher.
There are three manufacturing processes: casting, forging and steel.
There are three manufacturing processes: casting, forging and steel.
Scope of application: flexible coupling is suitable for hydraulic power generation, thermal power generation, coal, chemical industry, food processing plant, natural gas transportation and other industries.
Installation: when the pipeline needs to be turned over, only a few bolts of the joint can be removed, and any angle can be overturned without cutting and welding, which saves a lot of auxiliary work and expenses, reduces labor intensity and shortens the construction period. Compared with the flange connection, the efficiency is increased by 6-8 times, and the maintenance workload is very small. After the improvement, the clamp type flexible expansion joint without disassembly and direct welding is derived, which is more convenient for installation. Only the bolts need to be removed during maintenance. Other times are the overall situation, reliable and stable.
