Import Diaphragm Rubber Sheets & Rolls — Buy in Bulk from Supplier in India

Diaphragm Rubber Sheets & Rolls are produced by Steel Tube Engineering Co. using a high‑performance Nitrile (NBR) compound reinforced with either one‑ply or two‑ply nylon fabric. The sheets are offered in the BDR‑1370 grade with a density of 1.3 g/cc, hardness of 70 Shore A, tensile strength of 80 Kg/cm² and an elongation at break of 300 %. Sheet thickness is supplied between 3 mm and 12 mm and the material is finished smooth or with a texture impression.

In the oil, LPG and solvent‑resistant market, nitrile rubber is the standard choice because of its resistance to petroleum‑based fluids and its durability under pressure. Multi‑ply fabric reinforcement adds dimensional stability and allows the diaphragm to remain pressure‑proof even at the upper thickness limit. Typical industry practice for similar products includes thickness ranges from 2 mm to 15 mm and reinforcement fabrics such as polyester or aramid; the supplier can provide alternative fabrics on request, which is common for custom‑engineered diaphragms.

The sheets are commonly cut to size for control valves, pressure regulators and pump diaphragms, and are shipped either as flat plates or rolled sheets. Buyers should confirm the minimum order quantity, price and lead‑time directly with Steel Tube Engineering Co. as these details are not disclosed in the public listing. Storage must follow DIN 7716 guidelines - cool, dry and dark conditions between 10 °C and 30 °C, protected from ozone and acids - to preserve material integrity before installation.

Steel Tube Engineering Co. is located in Mumbai, Maharashtra, India (postal code 400003). The company is listed with a harbour‑level trust tier and currently shows a 0 % response rate, indicating that enquiries may require follow‑up through the platform’s messaging system.
