Metallic Expansion Joints/ Bellow Assemblies / Absorbators

Introduction
These are completely sealed units assembled in numerous ways with different types of end fittings as per the specific requirement of customer for various applications such as Axial, Universal, Gimbal, Hinged, Pressure Balance etc. SHREYANSH ENTERPRISE   has the right kind of design, engineering and manufacturing facilities as well as capabilities to match the requirements of EIMA. These allow greater control over quality during every phase of production. The device containing one or more bellows used to absorb dimensional changes such as those caused by thermal expansion or contraction of a pipe line, duct or vessel.

Range :

• Material
  Stainless Steel - AISI304, 304L, 316, 316L, 321, Inconel, Manel, Phospher Bronze, Brass, Mild Steel etc.
• Construction & Safety:
  Bellows are formed by roll forming process under the most exciting process control in house and permits no points of stess concentration. Bellows are employed in piping systems to absorb differential thermal expansion while containing the system pressure. They are being successfully utilised in refineries, chemical plants, fossils and nuclear power system, heating and cooling systems & cryogenic plants. Typical service conditions have pressure ranging from full vacuum to 1000 psig & temperature from - 420°F to 1800°F. Unlike the most commonly used piping components, a bellow is constructed of relatively thin guage of material in order to provide the flexibility needed to absorb mechanical and thermal movement expected in service. This requires design, manufacturing, quality, handling, installation and inspection procedures which recognize the unique nature of the product.
