Luke Steel is a top Houstan, USA-based manufacturer and supplier of Mild Steel Flanges. Focused on providing cost–effective, high–quality piping components, the company serves domestic as well as international markets. Committed to precision, performance, and customer satisfaction in every measure, Luke Steel manufactures flanges that meet international standards, making them suitable for a wide variety of engineering and industrial uses. Supported by strong manufacturing capacity and effective logistics, Luke Steel provides timely delivery, market competitive pricing, and tailor-made solutions for infrastructure construction, fabrication businesses, and utility services, hence becoming a brand name in most industrial segments.
The Mild Steel Flanges consist chiefly of iron with low carbon (0.05%–0.25%), which increases ductility, formability, and weldability. These flanges have moderate tensile strength usually between 400 and 550 MPa, which makes them well suited for general–purpose and low–pressure applications. They possess the properties of good impact resistance, uniform grain structure, and can be subjected to normal welding and machining. The plainness of their make leads to uniform performance under varied conditions, providing a hassle-free, low-maintenance option for piping and fabrication systems not in need of high pressure or corrosion resistance.

Mild Steel Flanges are used extensively in industries such as oil and gas, construction, water treatment, shipbuilding, and power generation. They are essential components in piping systems, serving to connect pipes, valves, pumps, and other equipment securely and efficiently. Their robust structure and weldable nature allow for custom fabrication to meet specific system requirements. These flanges also find use in HVAC systems, chemical plants, and manufacturing setups, where they provide reliable sealing and support in fluid handling and structural frameworks, particularly in low to moderate pressure environments.
Mild Steel Flanges are widely utilized in piping systems to join pipes, valves, pumps, and other devices for easy assembly and disassembly. They are appropriate for low to moderate pressure service such as water supply, HVAC equipment, fabrication facilities, and building. They are commonly used in the automotive, farming, and general mechanical industries and are appreciated for their cost-effectiveness, ease of assembly, and maintenance-convenient design. Although not suited to extremely corrosive or high-temperature applications, their use in utility–based and non–critical systems makes them a first choice for a myriad of engineering and plumbing applications.
