Accurate Engineering INDUSTRIES is one of the nation's largest distributor and supplier, stockist & distributor of Marine Grade Stainless Steel Pipe that are widely used for marine applications. We are also distributor & exporter of 304 Marine Grade Stainless Steel Pipe. In a marine environment, Marine Pipe Material must be made clear as to whether the stainless steel is simply near enough to the seashore such that it can be attacked by the chloride present in seawater by carried or splashing by the onshore breeze. Accurate Engineering Industries is well known as 316 Marine Grade Stainless Steel Pipe manufacturer in India.As a wide inventory of marine grade Pipe quality. Near the seashore, Stainless Steel 316L is typically considered the minimum grade of for Use.

We are one of the reputed to be a reliable manufacturer and supplier of Marine Grade Stainless Steel Pipe in different thickness, different diameter length, and in different quality. 304 marine grade stainless steel pipe has some degree of corrosion resistance, however, there are several grades of stainless steel that are far more suitable for use in marine environments. When these 316 marine grade ss pipes are exposed to underwater or wet environments, marine grade metals may be necessary to prevent the material from failing under the conditions. Marine Grade stainless steel Pipes are resisting corrosive effects that are common in a water environment. In the marine industry, these 304l marine grade stainless steel pipes are used most widely.
Grade 316 is the most widely used grade of stainless steel in marine applications. 304 Marine Pipe has more molybdenum than other austenitic stainless steels which helps it to resist pitting and other corrosive effects of salt water. Grade 304l is another marine grade stainless steel pipe, although it has less molybdenum than grade 316l making it a less desirable choice in chlorine-rich environments.
