Stainless Steel Welded Pipe
316l Stainless Steel Pipe Manufacturer

Top Stainless Steel Pipe Manufacturer, Stainless Steel Seamless Pipe Supplier in Malawi, ASME SA312 Stainless Steel Pipe in Malawi

Stainless steel pipe is a corrosion-resistant and long-lasting alloy of iron, carbon, and various concentrations of chromium and other elements. Stainless steel is a common option for a wide range of applications in numerous industries because of its high chromium content, which makes it highly resistant to rust and corrosion, even in hostile situations.

Siddhgiri Tubes, based in Mumbai, India, is a prominent Stainless Steel Pipe Manufacturer, Supplier & Exporter in Malawi. As a top stainless steel pipe manufacturer & supplier, we deliver higher pipes in accordance with different international standards. High-pressure equipment, boilers, heat exchanger tubes, air preheaters, steam release pipes, air cooler tubes, steam trap piping, and other applications all require ss pipes.

Stainless steel pipes are available in a variety of diameters, shapes, and grades to accommodate various uses. among the popular varieties of stainless steel pipes are:

Austenitic stainless steel pipes: The most popular and best at resisting corrosion, these pipes are made of stainless steel. It is frequently utilised in applications that call for high-temperature strength as well as oxidation and scaling resistance.

Ferritic stainless steel pipes: While less resistant to corrosion than austenitic stainless steel, they are nonetheless appropriate for some applications that do not need for high-temperature strength.

Martensitic stainless steel pipes: Compared to austenitic and ferritic stainless steel, martensitic stainless steel is more prone to corrosion, yet it is still strong and resilient. It is frequently employed in applications where great strength and wear resistance are necessary.

Stainless Steel Pipe Pressure Ratings Chart in Malawi

See the pressure rating and specifications of stainless steel seamless pipes, which come in round, oval, and rectangular shapes with thicknesses of 10/40/60.

The schedules are useful for determining the maximum pressure that each type of pipe can support. The greater the schedule, the higher the pressure containment. ASME SA312 Stainless Steel Pipe is utilized in applications where strength is the main factor.

Schedule 10 Stainless Steel Pipe is classified at relatively low pressures. We also create different grades. Our ASTM A312 Stainless Steel Pipe, like A312 TP304, is appropriate for high temperature services. We also produce all grades of stainless steel pipe in accordance with ASTM B36.19. Even though SS Round Pipe is the most widely used.

What is the Max. Working Pressure for Stainless Steel Pipe?

The different materials that go into making stainless steel pipes have different compositions. Each material grade has a yield and tensile strength value. The tensile strength is the point at which a pipe will burst under tension in opposing directions, whereas the yield strength is the utmost that a material can withstand before irrevocably changing shape.

Similar to yield and tensile strength, pipes have working pressure and bursting pressure. There are various pressures and temperatures that the pipes must withstand. You may determine the amount of pressure the pipe can withstand before it starts to change by looking at its maximum permissible working pressure. The bursting pressure is the pressure at which a pipe will begin to rupture. There are numerous acceptable values.
