  • Long service life

    The PE pipe has high molecular weight, good stability and anti-aging ability. Under normal operating temperature, the service life of PE pipe can be guaranteed to be more than 50 years.

  • Environmental performance

    PE pipes do not add metal stabilizers during the processing process, and the material is non-toxic, without scaling layer, and does not breed bacteria. It is a safe and hygienic pipeline material. PE material itself can be recycled and will not produce substances that have an impact on the environment.

  • Corrosion resistance

    The molecular structure stability of PE pipes is extremely high and there is no electrochemical corrosion. Among many pipeline materials, the corrosion index of PE pipes is relatively small, and apart from a few oxidants, they can withstand corrosion from various chemical media.

  • Impact resistance

    PE pipe is a high toughness pipe material with a fracture elongation rate of over 500%, which has impact and earthquake resistance, and strong adaptability to uneven settlement of the pipe foundation.

  • Low temperature resistance

    HDPE pipes have good low-temperature resistance and will not exhibit brittle cracking even in extremely low environments.

  • Wear resistance

    HDPE pipes have flat walls and low flow resistance, resulting in fluid friction performance, not only wear resistance but also high conveying efficiency.

Round Head Version Compression Fitting

How does the Round Head Version Compression Fitting ensure a leak-free connection?

The Round Head Version Compression Fitting ensures a leak-free connection through a compression mechanism that creates a tight seal around the pipe or tube.
Components:The fitting typically consists of three main components: the round head nut, the compression ring (ferrule or olive), and the body.
Compression Ring Placement:The compression ring is positioned around the pipe or tube before assembly.
Tightening the Nut:During installation, the round head nut is tightened onto the body of the fitting. As the nut is turned, it exerts pressure on the compression ring.
Compression of the Ring:The turning of the nut causes the compression ring to be compressed tightly against the surface of the pipe or tube. This compression creates a secure seal by deforming the compression ring around the pipe.
Sealing Effect:The deformation of the compression ring creates a seal that prevents fluid from leaking out of the joint. This seal is crucial for maintaining the integrity of the plumbing system.
Uniform Distribution of Pressure:The design of Round Head Compression Fittings is such that the pressure applied by the compression nut is evenly distributed around the circumference of the compression ring. This uniform distribution ensures a consistent and reliable seal.
Material Compatibility:The materials used for the compression ring, such as brass or stainless steel, are chosen for their resilience and ability to maintain their shape even under pressure. This contributes to the effectiveness of the seal.
Avoiding Over-Tightening:It's important not to over-tighten the round head nut, as excessive force can damage the compression ring or the pipe itself. Over-tightening can lead to leaks or compromise the integrity of the connection.
Conical or Tapered Design:Some compression fittings have a conical or tapered design, which enhances the sealing effect by providing a gradual and secure compression around the pipe.

What precautions Round Head Version Compression Fitting should be taken during installation?

During the installation of Round Head Version Compression Fittings, it's crucial to follow proper procedures to ensure a secure and leak-free connection. 
Proper Pipe Preparation:Ensure that the ends of the pipes or tubes being connected are clean, smooth, and free from any burrs or debris. Use a pipe cutter or appropriate tool to achieve a straight and even cut.
Correct Sizing:Verify that you are using the correct size of Round Head Compression Fittings for the pipes or tubes. Using fittings of the wrong size may result in a poor seal and potential leaks.
Use of Compression Rings:Place the compression ring (ferrule or olive) on the pipe before inserting it into the fitting. Ensure that the compression ring is positioned correctly, with the tapered or beveled edge facing the fitting.
Hand Tightening First:Initially, hand-tighten the round head nut onto the body of the fitting. This helps prevent cross-threading and allows for a more controlled tightening process.
Avoid Over-Tightening:Do not over-tighten the nut. Over-tightening can damage the compression ring, the pipe, or the fitting itself. Follow the manufacturer's recommended torque specifications to achieve the proper compression without causing damage.
Use of Tools:If using tools for tightening, use adjustable wrenches or other suitable tools. Be cautious not to apply excessive force, and ensure that the tool is properly positioned to avoid slippage.
Check for Alignment:Verify that the pipes or tubes are properly aligned within the fitting before tightening. Misalignment can lead to leaks or an improper seal.
Inspect Compression Rings:Before installation, inspect the compression rings for any signs of damage or wear. Replace any damaged or worn compression rings with new ones.
Thread Sealant:In some cases, depending on the application and materials used, it may be necessary to apply an appropriate thread sealant to the threads of the fitting. Follow manufacturer recommendations regarding the use of sealants.
Test for Leaks:After installation, perform a leak test by pressurizing the system and checking for any signs of leakage around the connection. This can be done using a soapy water solution to detect bubbles.
