When pressure is applied, unbraided hoses tend to elongate axially. To restrain this, an external layer of SS wire braid is provided. The braid also makes the assembly pressure compatible. Sometimes two or even three layers of braiding are provided for high pressure applications. The braiding is highly flexible and follows the movement of the hose. The braid is normally manufactured in SS 304 wire. However SS 316 and 321 braids are also available. We also supply wire braid in different configurations as per customer specifications.

High physical strength combined with light weight.
Suitable for wide temperature range (-200° C to + 550°C)
Good corrosion resistance. Resistance to fire, moisture, abrasion and penetration.
Absorbs vibration and noise from pumps, compressors, engines etc.
Compensates for intermittent or constant movement.
Compensates for thermal expansion of contraction of piping.
Corrects problems of misalignment.
A flexible and quick alternative for rigid piping in difficult locations.

Stainless Steel Braided Flexible Pump Connectors

Stainless Steel Flexible Pump Connectors are designed for mechanical equipment to isolate vibration, relieve stresses, reduce noise, absorb small movements and to facilitate installation. Flexible pump connectors to use suppress vibration from pump, to absorb intermittent lateral movements in pipelines and to compensate for subsidence when pipelines cross building movement lines.

Stainless Steel Flexible Pump Connectors are manufacturing in austenitic steel ANSI 321 (DIN EN 1.4541) & ANSI 316L (DIN EN 1.4404) grades with over ANSI 304 (DIN EN 1.4301) / ANSI 316L (DIN EN 1.4404) single or double wire braided. Hoses conform to BS 6501, Part-1:2004 / ISO 10380 : 2003.

Note:

Flexible pump connector are designed the test pressure is 1.5 times of the max. Working pressure.
The burst pressure is 4 times of the working pressure.
They are use for full vacuum and operating temperature of -200° C to +700° C.
Flexible Pump Connectors are not suitable for absorbing AXIAL Movement.
We are also manufacturing higher pressure Pump Connectors as per customer’s specification.

Advantages of Flexible pump connector:

Absorbs misalignment, vibration and sound.
Withstands high pressure.
Excellent corrosion-resistance.
Excellent for use with moderate many solvents, chemicals, most oils and grease.

Jacketed Flexible Hose

AYTC also supplies jacketed flexible hose assemblies. The Inner annular corrugated stainless steel flexible metallic hose conveys the fluid and jackets annular corrugated stainless steel flexible metallic hose for heating or coolant fluid or protective the hose and both Inner and jacketed hoses are highly flexible.

We are using our annular corrugated stainless steel flexible metallic hoses ANSI 321 / 316L with ANSI 304 single wire braiding. We will provide both the end flange fittings swivel or fixed type and for inlet & outlet heating or cooling fluid end connection we will provide flange end or threaded end at an offset angle of 180°, Hoses conform to BS 6501, Part-1:2004 / ISO 10380:2003.
