METAL BELLOWS

Back

Metal Bellows

Our bellows are designed to absorb and reduce vibration and relieve structural stress from working under pressure, extreme temperatures, and other variables. And now we can make Exhaust Bellows, Bellows Assembly, Edge Welded Bellows and Metal Hoses.

Exhaust Bellows

The Exhaust bellows are used for absorbing and reducing vibration for the exhuast pipes. It is usually designed in Stainless steel whose Flex section has an outside S/S braid and a convoluted tube and then another S/S braid on the inside for added for strength. And it will reduce premature cracking of manifolds and downpipes and help extend the life of other components.

Bellows Aseembly


In order to meet customer requirements for movement, pitch, height, bend radius, thickness and plies, and other design considerations. We have the ability to design and produced the molds with in-house tool making capabilities. In another word, we can create custom metal bellows that match your exact specifications.

Now we can produce the bellows from size DN6 to DN300 diameter for the bellow assembly with thinnest wall 0.09mm single-ply or multi-ply connected with different ends connection, such as KF or all different standards flanges. 

Usually the bellows are used for valve applications, and also some pressure sensitive applications. And whatever your application which need the bellows assembly, then we can meet your requirements including the vacuum and pressure requests.

Edge Welded Bellows


The Edge Welded bellows also called Diaphragm Bellows which is consists of two rings. These rings are edge welded together inside and outside. Edge welded bellows guarantee a very high flexibility.

These bellows are used in measuring & control devices, mechanical seals for pumps, accelerator, aerospace, nuclear fusion, atomic energy, semiconductor, solar photovoltaic, pharmaceutical equipment, vacuum equipment, and high-level industrial.

we possess the capability to manufacture edge welded bellows in stainless steel 300 series and exotic metals including Hastealloy C-276 and Inconel 600, 625 or 718, in sizes ranging from minimum of ID5mm to ID600 mm 

The precision-formed diaphragms are edge welded by micro plasma or laser welding using special fixtures to prevent uneven stress build up. The thickness of diaphragms varies between 0.127mm and upward 0.30mm.


Flexible Hoses


Metal hoses are suitable for a wide range of applications in the steelmaking, chemical, smelting, petrochemical, automotive, materials handling and power generation industries, and many other fields. The hose can be used for the conveyance of fluids and gases, the correction of misalignments and the absorption of movements and vibrations.

The advantage of metal hose over other materials is its capability to withstand high temperatures, impacts, and corrosive substances and atmospheres.

Key Features: Flexible, excellent temperature resistance. Braiding prevents elongation.

Temperature: -200°C to +700°C

Applications: Gas, steam, chemicals, hot water.

Length (mtrs): Made to order.

End connection : Made to order.

Our stainless steel hose assemblies are available with a wide range of end connections, bore sizes and lengths according to our customer requirements usually range of Sizes from DN10 to DN300 and material can be Hose convolution SS304,SS321 ,SS316 then wire Braid in SS304 and SS316.
