Metal Bellows

Necessity

Weldmac needed specialized bellows assemblies for its own manufacturing processes however there was no product on the market that met our high internal standards. Upon discovering this, the team at Weldmac set out to apply it’s philosophy and approach to research and create metal bellows to the highest possible standards.

Quality

Weldmac is now produces aerospace-quality, metal bellows as part of the metal fabricated assemblies provided to companies in Aerospace, Defense, manufacturing, food processing, refinery, power generation, water treatment, mining and other industries. Like much of the components we produce, Weldmac’s bellows are manufactured to meet the requirements of the aerospace industry. This means they last longer, perform better, are constructed out of a wider range of materials to meet high temperatures and have excellent corrosive properties.

Capabilities

Weldmac’s Current facilities are capable of constructing metal bellows in sizes of 100 or more inches in diameter. Because Weldmac has the highest-level quality control and process certifications, its bellows far exceed the typical commercial standards.

Weldmac’s rigorous standards for quality require unique instrumentation such as micro processors, sensors and digital read out. Weldmac has set out to produce a product that exceeds most quality requirements regardless of the application. Weldmac’s CNC approach to this manufacturing process has resulted in a higher quality, tighter tolerance, more repeatable product for it’s customers. Weldmac offers the same standard for our hydro-formed bellows. Everything is CNC controlled including internal pressures, feed rates and dwell time.

Metal Expansion Joints

Weldmac Manufacturing Company is proud to offer aerospace grade metal expansion joints for it’s commercial clients. If you are looking for the highest quality metal expansion joints available, call Weldmac today.

Expansion joints are necessary in systems that convey high temperature or pressurized commodities in the form of liquid, steam or exhaust gases.

Bellows are a common type of expansion joint for a pipe system. As you probably notice, a bellows consist of a series of convolutions (ribs). The convolutions handle the internal pressures of the application. The key is the flexibility of the bellows allowing it to accept movement or changes in position of one or both ends.

An expansion joint is a useful component in an infinite number of applications. Metal expansion joint assemblies are commonly used for all kinds of industries and applications including:

  • Power Generation
  • Co-Generation, Petrochemical
  • Chemical Processing
  • Pulp Paper Manufacturing
  • Cryogenic Process
  • Pressure Vessel and heat Exchanger Fabricators
  • Heat Steam recovery Generator
  • Architect Engineering
  • Construction Engineering
  • Mechanical contractor
  • Pharmaceutical manufacturing
  • Gas Turbine, Gas Transmission
  • Ship building and Repair
  • Diesel Engine Mfg, Incineration
  • Waste Water Treatment
  • Metal Smelters
  • Pollution Control

When Weldmac Manufacturing Company needed high quality, high precision metal bellows there was nothing on the market that met it’s needs. That is the main reason Weldmac entered the market. Utilizing 50 years experience in metal fabrication for some of the most demanding clients, Weldmac has developed a product to suit any requirement.

Call us today to discuss how Weldmac can engineer and manufacture an expansion joint system that will meet your needs.
