Stainless Steel Hoses
Stainless steel annular corrugated metallic flexible hoses are manufacturing in austantic steel ANSI 321, 316, 316L & 304 grades conforming to BS 6501, Part-1 : 2004 / ISO 10380 : 2003. The annular corrugated metallic hose body provided the flexibility and pressure tight core of the assembly. We also manufacture highly flexible close –pitch hoses for special applications. Stainless steel annular corrugated metallic flexible hose are offered from Size : 1/4"(DN 6) to 12"(DN 300).
Stainless Steel Braids
When pressure is applied, unbraided hose tends 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 can also be manufactured. We also supply wire braid in different configurations as per customer specifications.

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.
