Products
Sangeeta Metal is a notable manufacturer, supplier and exporter of Stainless Steel Pipes and Tubes in various grades. We manufacture SS Pipes and Tubes using high-quality raw materials and advanced technology in various grades, sizes, specifications, thicknesses and dimensions as per client's requirements. All our SS pipes & tubes meet Indian and International standards like ASME, ASTM, ANSI, AISI, etc.
What are Stainless Steel tubes?
SS tubes are hollow cylindrical structures made from stainless steel, a versatile alloy containing a
high percentage of chromium, nickel, and other elements. This combination of elements gives stainless
steel its strength and ability to resist corrosion, making it ideal for various industrial applications.
As leading stainless steel pipe manufacturers in India, we offer a wide range of stainless steel welded pipes and tubes with excellent durability and quality. Our product range includes 304 stainless steel pipes that are affordable and well known for their good weldability and corrosion resistance. In high temperature applications, 310 Stainless Steel Tubes perform well with excellent resistance to oxidation. Our Stainless Steel 316 Pipes are suitable for chloride-containing environments and SS 347 Tubes are resistant to intermittent heating between 800 degrees F (427 degrees C) and 1650 degrees F (899 degrees C). Additionally, we also provide SS 304L Pipes and 904L Stainless Steel Pipes that resist corrosion in saltwater.

Are seamless stainless steel pipes stronger than welded pipes?
Yes, seamless pipes generally offer higher strength and better pressure resistance because they do not
have a welded joint.
Can stainless steel tubes be used in high-pressure applications?
Yes, stainless steel pipes are widely used in high-pressure systems such as oil & gas, chemical
processing, and power generation industries.
Do stainless steel pipes require maintenance?
No, stainless steel pipes require very low maintenance due to their corrosion resistance and long
service life.
Are stainless steel pipes and tubes suitable for drinking water systems?
Yes, stainless steel pipes are safe for drinking water applications as they do not contaminate water
and maintain hygiene standards.
Do stainless steel tubes resist high temperature conditions?
Yes, stainless steel pipes can withstand high temperatures, making them suitable for boilers, heat
exchangers, and industrial processing systems.
Are stainless steel pipes & tubes available in SS 304 and SS 316 grades?
Yes, SS 304 and SS 316 are the most commonly used grades for stainless steel pipes due to their
excellent strength and corrosion resistance.
Do stainless steel pipes get rusted easily?
No, stainless steel pipes do not rust easily; however, improper handling or exposure to harsh
chemicals may affect surface performance over time.
As a trusted SS pipe supplier in Mumbai, we offer stainless steel pipes and tubes in seamless, ERW, welded, fabricated and CDW types, with thicknesses ranging from 0.3mm to 50mm.
