36 Inch custom Pressure balanced expansion joint
January 4, 2022

Bellows Systems designs and delivers a 36 Inch Custom Pressure balanced expansion joint to a major aerospace engine manufacturer.

Bellows Systems Inc, recently shipped a 36 Inch custom Pressure balanced expansion joint to a major aerospace engine manufacturer. This pressure-balanced expansion joint will be used in a jet engine test facility in Florida to upgrade existing piping.

36 inch Custom Pressure Balanced Expansion Joint

The project was delivered within 10 weeks from design concept to delivery. As per the client’s requirement, we used Stainless Steel 304 Grade to build this 36-inch x 120-inch Expansion Joint.

A Pressure Balanced Expansion Joint (Elbow type) is normally a double bellows Expansion Joint with a side outlet between the bellows. The ends of the bellows are tied together so that as one bellows compresses due to axial movement, the opposing bellows open an equivalent amount.

Bellows Systems Inc designs and manufactures metal bellows, expansion joints, exhaust systems, and associated products. Our products are used in diverse industries such as Oil and Gas Transmission, Petrochemical plants and Refineries, Power Generation, Automotive, Aerospace and Defense, and many more.

Bellows Systems Inc ships another 36 Inch Universal Expansion Joint with Tie-Rods for an Oil Storage facility in West Africa!

As one of the Pioneers of the Expansion Joint industry Bellows Systems Inc recently shipped another 36 Inch [ 2.8 m long ] universal expansion joint with tie-rods. This high-pressure universal expansion joint will be used in an Oil Storage facility in West Africa.

Bellows Systems Inc undertook this project for an Oil tank rehab and expedited the entire process from design to fabrication within 6 weeks to meet the client’s tight timelines. As per the requirement, this was built with Stainless Steel Type 316 and was designed to take both axial and lateral movement.

Universal Expansion Joints are normally designed to absorb any combination of axial and lateral movement and angular rotation in multi-plane piping arrangements. They are extremely well suited to the absorption of large amounts of lateral displacement.

Based in Houston, the Energy Capital of the World, Bellows Systems designs and manufactures metal bellows, expansion joints, exhaust systems, and associated products. Our products are used in diverse industries such as Oil and Gas Transmission, Petrochemical plants and Refineries, Power Generation, Automotive, Aerospace and Defense, and many more.

Exhaust Manifold for Cooper Bessemer Z-330

40 Inch ID Exhaust Manifold for Cooper Bessemer Z-330

Bellows Systems recently shipped another set of Exhaust Manifold sections for Z-330 engine. Z-330 is the largest of the Copper Bessemer 2 stroke Integral Compressor Engines. The Z-330 exhaust manifold has 40inch ID dry manifold. 

Exhaust Manifold for Cooper Bessemer Z-330

The OEM sectioned manifolds for Z330, W330 and V250 engines have several problems that have been observed during continuous service. These issues are discussed in detail BSI service bulletin (SB-100) first issued in July 1983. These include,

Inner shell crack on an OEM Z330 manifold common section.
  • The 40in tube cracks around the junction of the cylinder exhaust chute.
  • The exhaust chute from the base flange to the inner shell/tube cracks.
  • The removable insulation blanket deteriorates over time.

BSI dry manifolds for Z330 have numerous improvements over the OEM units. These include,

  • The 40” inner shell construction using thicker (3/8”) wall plate.
  • The  cylinder chute to inner shell/tube weld is CJP (100% penetration) and back welded on the inside.
  • 3/4” thk. stainless steel rod stiffeners
  • The outside insulation jacket includes 2” thick ceramic fiber  insulation.
  • Fiber glass cloth covered insulation blankets for the expansion joint and bolt gap. Both of which are covered under metal insulation cover.

All structural problems encountered in the OEM manifold are addressed

Bellows Systems also offers conversion from 1 piece or 2-piece manifold to fully sectional dry manifolds.

Bellows Systems continues to innovate and provide superior Exhaust System products for the Natural Gas Compression Industry. We manufacture exhaust manifolds and support all major legacy integral gas compressor engines.

A complete lineup of Piping Expansion Joints and Piping Bellows by Bellows Systems Inc
March 26, 2021

A complete lineup of Piping Expansion Joints and Piping Bellows by Bellows Systems Inc

Piping engineers are continuously faced with problems involving thermal movement, instability, limiting forces on equipment, and absorption of vibrations. The piping design must balance the economics of pipe loops and offsets, space, and fabrication against the cost of expansion joints.

Bellows Systems has made piping engineers lives easier by providing cost-effective, engineered bellows and expansion joint solutions for their piping designs. Its Kopperman Division established in 1894 is one of the oldest manufacturers of expansion joints.

Piping bellows and expansion joints may be used to absorb direct axial expansion or contraction, to absorb equipment vibration, to provide limitation of forces applied to critical equipment and to improve line stability through reduction and control of loads on pipelines.

We offer a complete lineup of piping expansion joint design options and standard sizes ranging from as small as 1” to 48” pipe OD. We can fabricate bellows from single-ply wall thickness of 0.004” to 0.072” and multi-ply designs with up to 6 layers for different pressure classes and vibration loading. Our high-pressure expansion joints can optionally be constructed with root reinforced bellows designs with integral root rings or equalizing rings

Two different dual bellows type universal expansion joints,

  • 36” ID x 41” long with flanges for a compressor station in Texas, CAT GCM – 34 Exhaust.
  • 41” ID x 26” long with weld ends for a refinery in South America.

Dual universal expansion joints are the simplest type of universal expansion joint. They are typically used in low-pressure applications, such as exhaust ducting. They can absorb both axial and lateral movement in the piping.
