Sumer Metal Industries Private Limited is a leading manufacturer, supplier, and exporter of Stainless Steel 904L Needle Tubes. The company has established a strong reputation for delivering high-quality tubes that cater to industrial applications worldwide. Their products are exported to countries including Oman, Qatar, Saudi Arabia, UAE, Kuwait, Spain, Germany, USA, Canada, and multiple regions across Africa, ensuring global availability and reliability.
Stainless Steel 904L is a high-alloy austenitic stainless steel, recognized for its exceptional corrosion resistance in aggressive chemical environments. The 904L grade contains high levels of nickel, chromium, molybdenum, and copper, which make it highly resistant to pitting, crevice corrosion, and acid attacks, particularly from sulfuric and phosphoric acids. This makes 904L needle tubes ideal for chemical, pharmaceutical, and food-processing industries.
Sumer Metal Industries produces needle tubes in both seamless and cold-drawn forms, offering precise dimensions and smooth finishes. The tubes are manufactured to meet international standards such as ASTM B677 and ASTM A213, and are available in a variety of sizes, wall thicknesses, and lengths, including cut length, single random, and double random lengths. This ensures versatility for a range of industrial applications
The company ensures strict quality control throughout the production process. Each Stainless Steel 904L Needle Tube is solution-annealed and pickled, providing excellent surface finish and maintaining the steel’s mechanical properties. The tubes also undergo dimensional inspection and testing to guarantee uniformity, strength, and compliance with industry standards, making them suitable for high-pressure and high-temperature environments.
