Product Description
Tied Bellows provided by our company, are mostly used for absorbing the thermal expansion. These bellows are designed to have a fixed overall length. They are highly designed by our workers, by using high grade raw materials. These bellows are also widely made to contain pressure thrust. Our offered Tied Bellows are tested under different parameters to ensure its high quality. These bellows are simple to install as well as easy to operate. These bellows are very economical and can be easily availed by our clients, at nominal prices.
Customizable Sizing and MaterialsOur tied bellows expansion joints are available in sizes from DN25 to DN1000, with customization to fit specific project requirements. Constructed from premium materials such as stainless steel, carbon steel, Inconel, Hastelloy, and PTFE-lined options, they provide optimal corrosion and temperature resistance for diverse industrial uses.
Comprehensive Movement CapabilityDesigned to accommodate axial, lateral, and angular movements, these expansion joints effectively compensate for thermal changes and mechanical stresses in pipelines. This makes them a reliable solution for demanding applications in sectors like oil & gas, power generation, and chemical processing.
Quality Assurance and Standards ComplianceEach expansion joint is 100% hydro tested to ensure leak-free performance and reliability. Our products adhere to EJMA and ASME standards, confirming their suitability for high-pressure environments and compliance with global industry benchmarks.
FAQs of Tied Bellows:
Q: How are tied bellows expansion joints installed for pipeline applications?
A: Tied bellows expansion joints are installed by connecting their endsflanged, butt weld, or socket weldto pipeline sections. The process involves precise alignment and securing with appropriate fasteners or welding techniques, ensuring a leak-proof and durable integration with the system.
Q: What benefits do tied bellows provide in HVAC, chemical, and power plant systems?
A: These bellows effectively absorb thermal expansions and vibrations, mitigating stress on piping systems. Their corrosion resistance and high temperature tolerance up to 400C help maintain system integrity in demanding environments, reducing maintenance and prolonging operational life.
Q: When is it necessary to customize the size or material of a tied bellows expansion joint?
A: Customization is advisable when standard sizes (DN25DN1000) do not fit the pipeline configuration or when the operating media require specialized material properties, such as high corrosion resistance or compatibility with aggressive chemicals. Our team can assist in designing bespoke solutions as needed.
Q: Where can tied bellows expansion joints be used within industrial sectors?
A: They are widely applied in pipelines across oil & gas plants, power generation facilities, chemical manufacturing units, and HVAC systems. Their versatility and compliance with ANSI/DIN/IS flange standards make them suitable for local and international projects.
Q: What is the process for leak testing tied bellows expansion joints?
A: Every unit undergoes a rigorous 100% hydrostatic leak test to verify its pressure containment capabilities and ensure there are no leaks. This process upholds both safety and quality standards before delivery and installation.
Q: How does the optional inner sleeve or liner enhance the tied bellows performance?
A: An inner sleeve or liner can be added on request to reduce flow-induced turbulence, protect the bellows from abrasive media, and extend the units lifespan, making it especially beneficial for applications involving gas, liquid, or steam transportation.
