Description

Stainless steel expansion joints, also known as stainless steel expansion joints, stainless steel thermal expansion joints with inner sleeve, are crucial mechanical devices that help absorb movements caused by temperature changes on pipelines. Manufactured directly at the factory of TAN DAT MECHANICAL TRADING AND SERVICE CO., LTD. (HCMC), the product well meets strict technical requirements for durability, pressure resistance, and flexibility during system operation.

Structural characteristics and operating principle of stainless steel expansion joints

The product is designed with a multi-layer corrugated stainless steel bellows to effectively absorb the axial thermal expansion of the pipeline when the fluid temperature changes. Depending on the technical requirements of the project, the device can be fabricated as a single-acting or double-acting expansion joint.

In addition, the expansion joint is equipped with tie rods to limit travel, ensuring high safety during system operation. The overall design of the product is calculated based on the actual temperature, pressure, and travel of each specific pipeline route.

Frequently asked questions about stainless steel thermal expansion joints

How is an expansion joint different from a flexible joint?
Expansion joints use bellows to absorb thermal axial expansion; flexible joints feature a braided cover, primarily for vibration absorption and lateral misalignment. Long steam or hot water pipelines typically require expansion joints.
What information is needed to order thermal expansion joints?
DN, installation length, required expansion stroke, design temperature and pressure, medium, and flange standard. If you have an old sample, you just need to send photos and dimensions.
What is the function of the tie rods on an expansion joint?
Tie rods limit the extension-compression stroke, withstand pressure thrust forces, and maintain the joint at the installation length during transportation and construction.

Product reviews

Technical assessment Tan Dat Flex engineering team

Stainless steel expansion joint / bellows compensator belongs to our stainless steel thermal expansion joints range. Material: 304 stainless steel (316 on request). Our engineers recommend it when you need this: absorbs axial thermal expansion and reduces stress on welds, supports and equipment. For the longest service life, choose the right specification and follow the installation guide.

Strengths
  • Absorbs axial thermal expansion and reduces stress on welds, supports and equipment
  • Durable stainless steel that withstands heat and rust in normal service
  • Made to order in the size, end connection and material your project needs
Selection & installation notes
  • Movement must be calculated and guides/anchors installed correctly for stable operation
  • For chloride, sea water or strong chemicals consider upgrading to SS316
  • When ordering, share pressure, temperature, medium and installation size for an accurate quotation
