Import Expansion Breather Spring For Insulation Bands — Buy in wholesale FOB from Supplier in India

The Expansion Breather Spring for Insulation Bands supplied by Heatcon Insulation is a stainless‑steel spring designed to be fitted onto metal banding to allow controlled expansion and contraction. Each spring is manufactured for 19 mm (¾ inch) banding and is supplied in standard lengths of 50 mm (2 in) or 100 mm (4 in). Heatcon offers the springs in three grades of stainless steel - SS304, SS316 and SS316L - with wing‑type seals that slide over the band before being locked in the spring’s spaced openings. The product is shipped from the company’s Mumbai facility in Maharashtra, India.

The stainless‑steel construction gives the spring excellent corrosion resistance for oil‑field environments, and the three grades allow buyers to match the material to service conditions. In the insulation industry, a spring rate of about 5 N/mm and a load capacity near 200 N are typical for 50 mm length springs, providing sufficient tension without overstressing the band. The springs are supplied with a mill‑finish surface; additional passivation can be requested if higher chemical resistance is required. Typical operating temperatures range from - 20 °C to 200 °C, matching the limits of the SS304/SS316 families.

These breather springs are commonly used by pipe‑lining contractors, oil‑and‑gas service firms and manufacturers of insulated pipe bundles that need to accommodate thermal expansion. Buyers usually request bulk quantities and specify incoterms such as FOB Mumbai or CIF destinations; packaging is typically ten springs per cardboard box, wrapped to prevent damage. As the listing does not disclose minimum order quantities, lead times or price, importers should contact Heatcon directly to confirm those trade details.
