Description


Metal Expansion joints

Metal bellows expansion jointsare ubiquitous to heavy industrial markets. If there is fluid or gas movement, be it in the petrochemical, electric power supply, paper and pulp or a variety of OEM industries, optimal operation and "up-time" require state-of-the art piping systems to keep your plant competitive, or better, ahead of the curve. You know your business, and you know that in order to be profitable, your system must run at maximum efficiency. Metal Bellows Expansion Joints allow you to control fluid movement and containment in your system under a wide variety of pressures, thermal expansion and contraction, pulsations, vibration, equipment movement and convoluted routing requirements.
Typically, the key component of an expansion joint is the Metal Bellows element. Flexibility is paramount in containing the media and the pressure inherent in the system. Metal bellows expansion joints, thin-walled, corrugated membranes, provide this flexibility.

 MATERIAL

  • Stainless Steel - Type **0 austenitic series  
**4 (ASTM A******4)

It is the most common grade and services a wide range of applications. It is thermal resistance, corrosion resistance, with nicer cold crushing strength and mechanical properties. Type **4 resists nitric acid and sulfuric acids at moderate temperatures and concentrations. Bellows supplied in this grade are usually used on water or steam applications.The temperature range varies from ***2℃ to **8℃.

**6 (ASTM A******6)

The second most common grade (after **4); Alloy addition of molybdenum prevents specific forms of corrosion. It is also known as marine grade stainless steel due to its increased resistance to chloride corrosion compared to type **4. Some typical uses include high sulphur crude oils, brackish waters, flue gases ,food processing and numerous applications in chemical and petrochemical processing. 


**6L (ASTM A******6L)

Extra low carbon grade of **6, generally used in stainless steel watches and marine applications due to its high resistance to corrosion.


**1 (ASTM A******1)

Similar to **4 but lower risk of Weld Decay due to addition of titanium, the addition of titanium also make it have better ability to prevent intergranular corrosion and high temperature resistance. The temperature of Type **1 is range from **6℃ to **0℃. The standard catalog exhaust joints are made from this material because of the high operating temperatures they withstand. 
  • Nickel alloys
Alloy **0 (ASTM B******0)

The application temperature of Alloy **0 is about **0℃.It has nicer ability of creep resistant , corrosion resistance and rapture stress resistant properties. No matter sub - zero ,indoor temperature or high temperature which below **0℃,it always has better mechanical properties. It is widely used in variety of difficult service conditions.
