HEBEI GAIN TRADING CO.,LTD’s “SZ” Brand—encompassing carbon steel pipe fitting, cs elbow, cs fittingsa carbon steel pipe—epitomizes 26 years of excellence. Guided by “Quality, versatility, and reliability,” the company delivers solutions trusted in critical pipelines worldwide. From small-scale residential projects to large industrial complexes, “SZ” Brand products prove that precision in fittings builds the backbone of durable infrastructure.
Carbon steel pipe fitting is a cornerstone product of HEBEI GAIN TRADING CO.,LTD, a subsidiary of Hebei Wanda Malleable Iron Corp.,Ltd established in 1997. Under the “SZ” Brand, these fittings are engineered to connect, redirect, or seal pipelines conveying gas, water, oil, and steam—critical for industries like petroleum, chemical, and construction.
Crafted from high-grade carbon steel (ASTM A234 WPB, Q235, 10#), carbon steel pipe fitting units offer exceptional strength, withstanding high pressure and temperature fluctuations. They come in diverse types: tees (straight and reducing), elbows (45°/90°/180°), reducers (concentric and eccentric), and caps, available in sizes from 1/2” to 48” (DN15-DN1200). Surface treatments include black paint, anti-rust oil, and hot-dipped galvanization, ensuring corrosion resistance in harsh environments.
Adhering to international standards (ASTM B16.9, JIS B2311, DIN 2605), carbon steel pipe fitting from HEBEI GAIN ensures global compatibility. Backed by ISO9001, SGS, and BV certifications, each fitting undergoes rigorous testing—including pressure checks (up to 2.5MPa)—to guarantee leak-proof performance. This commitment stems from a 2005 incident: a client reported fitting failures in a chemical plant, prompting the company to upgrade its quality control, now achieving a 99.9% defect-free rate. Today, “SZ” Brand carbon steel pipe fitting serves 40+ countries, reflecting the core value: “Strength in every connection.”
Cs elbow (carbon steel elbow) is a vital subset of carbon steel pipe fitting, designed to redirect fluid flow in pipelines. HEBEI GAIN’s cs elbow units are available in 45°, 90°, and 180° configurations, catering to varying layout needs—from tight corners in industrial machinery to long-distance oil pipelines.
Made from ASTM A234 WPB and Q235 carbon steel, cs elbow features seamless or welded construction, with wall thickness ranging from SCH5 to XXS to handle pressure demands (ideal for high-pressure systems like power plants). The hot-dipped galvanized variant resists rust in coastal or humid areas, while black paint finishes suit dry industrial settings.
A 2019 project in a Russian oil refinery showcased their durability: 500+ 90° cs elbow units operated flawlessly under 10MPa pressure and -30°C temperatures. This success reinforces “SZ” Brand’s focus on engineering for extremes, with each cs elbow machined to precise angles (tolerance ±0.5°) for smooth flow transition.
Cs fittings (carbon steel fittings) is an umbrella term for carbon steel pipe fitting, encompassing all types—tees, elbows, reducers, and caps—offered by HEBEI GAIN. This versatility makes cs fittings suitable for diverse applications: from residential gas lines (1/2” tees) to large-scale petroleum pipelines (48” reducers).
Cs fittings share core traits: carbon steel construction, welding connections, and compliance with global standards. The “SZ” Brand offers both equal and reducing variants, allowing seamless integration of different pipe diameters. For example, a reducing tee in cs fittings can connect a 4” main pipe to 2” branches, critical for distributing oil in refineries.
HEBEI GAIN’s cs fittings are customizable: clients can request specific wall thicknesses (SCH10 to XXS) or surface treatments, with a minimum order of 10 tons per specification. This flexibility, paired with a 30-day delivery window, has made “SZ” Brand cs fittings a preferred choice for time-sensitive projects—aligning with the company’s “Customer first” ethos.
Carbon steel pipe is the perfect counterpart to carbon steel pipe fitting, forming integrated systems in pipelines. HEBEI GAIN’s carbon steel pipe—made from the same high-grade carbon steel (ASTM A234 WPB, Q235)—ensures material compatibility, minimizing galvanic corrosion and ensuring joint strength.
Available in sizes from 1/2” to 48” (matching carbon steel pipe fitting), carbon steel pipe features seamless or welded construction. Seamless pipes suit high-pressure applications (e.g., steam lines), while welded pipes are cost-effective for low-pressure systems (e.g., water supply). Wall thicknesses (SCH5 to XXS) mirror those of cs fittings, ensuring pressure resistance across the entire system.
A 2020 case study in a Middle Eastern gas field highlighted their synergy: carbon steel pipe paired with 90° cs elbow and tees maintained integrity under 15MPa pressure, with zero leaks after 2 years. This system-level reliability underscores HEBEI GAIN’s focus on holistic solutions, where carbon steel pipe a carbon steel pipe fitting perform as a unified force.
