Rubber Coated U bolts | U Bolt with rubber sleeve | Insulated U bolt pipe clamps

Rubber coated U bolt pipe clamps Overview

Rubber coated U bolt is well known as Rubber insulated U bolt, and some times people call it Rubber cushioned U bolt clamp also. It is a galvanized U bolt or stainless steel U bolt with rubber sleeve. This is the most widely used type of insulated U bolts. Our pipe clamp factory manufacturer Rubber coated U bolts in wide range of materials and full size ranges.

Rubber insulated U bolt is usually made of a standard hot dipped galvanized, cold zinc plated or stainless steel U bolt, cushioned with a seamless, good vulcanizable, polyolefin material coating or insulation. The most popular rubber insulated U bolt is EPDM coated U bolt.

Rubber Coated U bolt is especially designed to minimise vibration transmission between pipe and hanger, and also preventing corrosion between different kinds of metals, by eliminating any possible metal to metal contact between the top and sides of the pipe.

Specifications of TEFLON coated U bolts

As the leading China U bolt pipe clamp manufacturers, our U bolts are manufactured as per:

  • German standard: DIN 3570;
  • ASME B18.31.5
  • Chinese standard: JB/ZQ 4321
  • and other customized specifications, customer’s drawings.

All the U bolts with above specifications can be coated with PTFE coating /Teflon coating or FluoroPolymer coating to make the PTFE coated U bolt clamps.

We can manufacturer and supply customized Teflon coated U bolts according to customer’s drawings.

Size range of Teflon (PTFE) coated U bolt clamps

Our factory manufacturer (PTFE) Teflon coated U bolts / PTFE lined U bolts / PTFE insulated U bolts with full ranges of sizes of:

  • 1/2″ (DN15) to 36″ (DN900)

Thread sizes of the U bolts are available from M6 to M56, we can provide both metric thread U bolt and UNC thread U bolt clamps.

Advantages of our PTFE coated U bolts/ Insulated U bolts

  • Teflon Coated U bolts provide a longer lifespan on your U bolt clamps. Also, the PTFE coating serves as additional layer of protection for the U bolt clamps as they are manipulated and imbedded into their place. PTFE (Teflon) coating has proven to improve the strength and lifespan of a U bolt.
  • PTFE Coated U Bolt clamps have a Low Coefficient of Friction. The coefficient of friction of PTFE is generally in the range of 0.05 to 0.20, depending on the load, sliding speed, and particular PTFE coating used.
  • PTFE insulated U bolts have excellent Corrosion resistant performance. The corroded nuts and bolts become a fragile liability when bearing heavy loads, so the PTFE coating or PTFE insulation prevents your facilities from long term damage.
  • TEFLON Coated U bolt clamps has excellent resistance to the elements as: weather, sunlight, salt water;
  • U Bolt with Teflon has good Heat Resistance performance. U bolt clamps with PTFE coating can operate continuously at temperatures up to 260°C/500°F. PTFE Coating U Bolts have Cryogenic Stability. Many PTFE industrial coatings withstand severe temperature extremes without loss of physical properties. PTFE (Teflon) industrial coatings may used at temperatures as low as -270°C/-454°F.
  • PTFE /Teflon Lined U Bolt clamps have good Chemical Resistance performance. PTFE coating / PTFE insulation is normally unaffected by chemical environments. The only chemicals known to affect all PTFE coatings are molten alkali metals and highly reactive fluorinating agents.

Applications of PTFE /TEFLON Coated (Insulated) U bolts

Mostly our PTFE coating U bolts are used in marine, ship building, offshore oil and gas industries. Besides these, as meeting high industry standards, our PTFE Insulated U bolt pipe clamps can also be used in a wide range of industries, including:

  • Marine, ship building, offshore industries
