No matter what industry you’re in DEP can provide the materials you need, including API, ASTM, ASME, NACE, DIN, AISI, MSS,JIS specifications. With more than 10 years of combined experience, vast industry knowledge, competitive prices, the ability to procure hard-to-find products and fast delivery, we help you complete your projects on time and on budget.
Our range of standard and special grade welded and seamless pipes are distributed to a wide range of different industries including;
We can also provide you with any of the special services you need to ensure your special project requirements are met, including threading, fabricating, coating and logistics.
We can offer Seamless Steel Pipe in Carbon, Stainless, Chrome Alloys, and Nickel & exotic grades. Seamless steel pipes are used because of their increased ability to withstand pressure, their excellent uniformity of shape, and their greater strength under loading. Although seamless pipe can sometimes be more expensive than welded pipe, this increased ability to withstand pressure allows you to use pipes that are thinner and lighter, which can help cut down on expenses. We can help decide which grade and type of steel pipe is needed for your project.
The benefits of seamless steel pipes make it the preferred material in an array of commercial pipe applications, including ship building, pipelines, oil rigs, oil field equipment, pressure vessels, machinery parts and offshore rigs. An additional benefit of seamless pipes is that they perform well in harsh conditions, which means that they can be used in extremely cold or hot environments.
If you’re considering seamless steel pipes for your next commercial pipe project, please get in touch with us and request a quote. As a leading international steel pipe supplier, we can provide you with the products you need and quickly ship your order to anywhere in the world.

Stainless steel pipe and tubing are used for a variety of reasons: to resist corrosion and oxidation, to resist high temperatures, for cleanliness and low maintenance costs, and to maintain the purity of materials which come In contact with stainless. The inherent characteristics of stainless steel permit the design of thin wall piping systems without fear of early failure due to corrosion.
Applications
Type 304 stainless is the most widely used analysis for general corrosive resistant tubing and pipe applications; it is used in chemical plants, refineries, paper mills, and food processing industries. Type 304 has a maximum carbon content of .08%. It is not recommended for use in the temperature range between 800°F and 1650°F due to carbide precipitation at the grain boundaries which can result in inter-granular corrosion and early failure under certain conditions.
Type 316 is widely used in the sulphite paper industry and for manufacturing chemical plant apparatus, photographic equipment, and plastics. Type 316L, like 304L, is held to a maximum carbon content of .03%. This permits its use in welded assemblies without the need of final heat treatment. It is used extensively for pipe assemblies with welded fitting. Other fields where stainless steel pipe and tubing are used are: aviation, electronics, automotive, cryogenic, marine, air conditioning and heating, medical, architectural and textiles.
