Flange Types: Diverse Offerings of Flange by HEBEI GAIN-----H2

Flange types from HEBEI GAIN cover a wide spectrum of designs, each tailored to specific pipeline needs, reinforcing the company’s role as a leading supplier of flange products. The core flange types include:

• Welding NeckFlanges: Featuring a long neck welded to the pipe, these flanges provide high strength, ideal for high-pressure systems (oil and gas transmission).
• Slip-On Flanges: Easy to install, sliding over the pipe before welding, suitable for low to medium pressure (water pipelines).
• BlindFlanges: Used to seal pipe ends, available in heavy-duty designs for industrial shutdowns.
• Puddle Flanges: A specialized type for waterproofing, discussed in detail later.

All flange types are crafted from malleable iron, chosen for its ductility and strength, with sizes from 1/4 to 6 inches—aligning with the company’s pipe fitting range. They come in galvanized (zinc-coated for corrosion resistance) and black (uncoated for dry environments) finishes, with heavy/light variants to match load requirements. Adherence to BS, DIN, and American standards ensures global compatibility, making flange types from HEBEI GAIN suitable for both domestic and international projects.

Flange: Core Pipe Fittings from HEBEI GAIN-----H2

A flange is a critical pipe fitting that connects pipes, valves, or equipment, enabling easy assembly and disassembly— a cornerstone of HEBEI GAIN’s product lineup. As a “SZ” Brand specialty, flange products are engineered to ensure leak-proof connections, even under high pressure and temperature fluctuations.

HEBEI GAIN’s flange units are manufactured using malleable iron, processed through heat treatment to enhance toughness and resistance to wear. This material choice ensures durability in diverse environments, from humid coastal areas (with galvanized finishes) to dry industrial zones (black finishes). The flange design includes bolt holes for secure fastening, with precise dimensional control (per BS/DIN/American standards) to ensure proper alignment with mating flanges or pipes.

Whether used in residential water lines or industrial oil pipelines, flange products from HEBEI GAIN undergo rigorous testing—including pressure tests and dimensional checks—to guarantee reliability. This focus on quality has made “SZ” Brand flange a trusted name in global pipeline systems.

Puddle Flange: Specialized Flange in Flange Types-----H2

A puddle flange is a specialized flange within HEBEI GAIN’s flange types, designed to prevent water leakage where pipes pass through walls or floors. This critical component is essential for basement, underground, or marine pipelines, where waterproofing is paramount.

HEBEI GAIN’s puddle flange features a circular plate with a central hole for the pipe, combined with a rubber gasket that seals the gap between the pipe and flange. When installed, the flange is embedded in concrete, creating a watertight barrier against groundwater or surface runoff. Made from malleable iron with galvanized finishes, it resists corrosion, ensuring long-term waterproofing performance.

Available in sizes from 1/4 to 6 inches, puddle flange units align with other flange types from the company, ensuring system compatibility. Whether for residential building basements or industrial wastewater plants, this specialized flange exemplifies HEBEI GAIN’s ability to address niche pipeline needs.

Flange 2 1 2: Specific Size in Flange Types-----H2

Flange 2 1 2 (2.5-inch flanges) are a specific size within HEBEI GAIN’s flange types, catering to medium-diameter pipelines commonly used in commercial and light industrial settings. These flanges balance versatility and performance, making them ideal for water distribution systems, small-scale oil lines, and gas pipelines in commercial buildings.

Flange 2 1 2 units adhere to the same standards as other flange types (BS, DIN, American), ensuring compatibility with 2.5-inch pipes and fittings. They are available in both galvanized and black finishes: galvanized variants for outdoor or humid environments (e.g., commercial sprinkler systems), black for indoor dry applications (e.g., industrial compressed air lines).

The 2.5-inch size is particularly popular due to its adaptability—large enough for meaningful flow rates but compact enough to fit in tight spaces. HEBEI GAIN’s flange 2 1 2 products are manufactured with precision, with bolt hole spacing and thickness matching international specifications, ensuring easy integration into existing pipeline systems.
