HEBEI GAIN TRADING CO.,LTD’s "SZ" Brand barrel nipple—including barrel nipple dimensions, 3 4 barrel nipple, barrel nipple 1 2, and barrel nipple 1 inch—epitomizes 26 years of precision. Guided by "Quality first, service always," the company delivers fittings trusted in global pipelines, from homes to oilfields. With strict standards, innovative production, and a customer-centric approach, "SZ" Brand continues to define excellence in pipe fittings.
A barrel nipple is a critical pipe fitting in HEBEI GAIN TRADING CO.,LTD’s portfolio, embodying the company’s 26-year legacy since 1997 as a subsidiary of Hebei Wanda Malleable Iron Corp.,Ltd. Under the "SZ" Brand, these short, threaded cylindrical fittings connect two pipes or fittings in straight-line pipelines, designed for gas, water, and oil transmission—essential for industries from construction to petroleum.
Crafted from high-grade malleable iron, barrel nipple units feature full threading (NPT, BSP) on both ends, ensuring secure, leak-proof connections. They come in galvanized (zinc-coated for corrosion resistance) and black (cost-effective for dry environments) finishes, with heavy/light variants to match pressure needs (up to 3000PSI). Sizes range from 1/4 to 6 inches, aligning with the company’s pipe fitting range, and comply with BS 21, DIN 2999, and ASTM A105 standards—guaranteeing global compatibility.
HEBEI GAIN’s barrel nipple production reflects its core value: "Precision in every thread." After a 2010 client complaint about mismatched threads, the company invested in CNC threading machines, now achieving ±0.01mm tolerance. Backed by ISO 9001, CE, and BV certifications, these fittings undergo pressure testing and material analysis, boasting a 99.8% defect-free rate. Today, "SZ" Brand barrel nipple is trusted in 40+ countries, a testament to reliability.
Barrel nipple dimensions are a hallmark of HEBEI GAIN’s commitment to precision, ensuring seamless integration with pipelines. Each barrel nipple adheres to strict dimensional standards: length (from 1/2” to 12”), outer diameter (matching pipe sizes), and thread pitch (conforming to NPT/BSP specs).
Key dimensions include:
These barrel nipple dimensions are documented in detailed catalogs, referencing BS, DIN, and American standards to guide clients. For custom orders, the design team uses 3D modeling to adjust lengths, ensuring perfect fits for unique pipeline layouts. This focus stems from a 2015 project: a European client required non-standard lengths for a refinery—HEBEI GAIN delivered within 72 hours, solidifying its reputation for flexibility.
The 3 4 barrel nipple (3/4 inch) is a versatile staple in HEBEI GAIN’s lineup, ideal for medium-flow pipelines in commercial and industrial settings. This size balances flow capacity and compactness, widely used in:
The 3 4 barrel nipple features galvanized/black finishes, with heavy-duty variants handling 2000PSI—suitable for oil lines. Its dimensions (length 2”–6”, OD 1.05”) fit 3/4 inch pipes, with threads compatible with "SZ" Brand elbows and couplings. A 2018 project in Southeast Asia saw 5,000+ 3 4 barrel nipple units deployed in a water treatment plant, performing flawlessly under humid conditions—proof of durability.
The barrel nipple 1 2 (1/2 inch) is a compact fitting, designed for low-flow, small-diameter pipelines—critical for residential and light commercial use. Common applications include:
With a length of 1”–4” and OD 0.84”, the barrel nipple 1 2 is lightweight (light variant: 0.2kg) yet sturdy, handling up to 1500PSI. Its galvanized finish resists rust in basements or outdoor installations, while black finishes suit indoor dry lines. HEBEI GAIN’s barrel nipple 1 2 is a top-seller in residential markets, with 30% of global sales—thanks to its affordability and compatibility with standard home pipelines.
The barrel nipple 1 inch is a medium-sized workhorse, bridging small and large pipelines in diverse applications. Its 1 inch diameter and 3”–8” length make it ideal for:
Constructed with heavy-duty walls (5mm thickness), the barrel nipple 1 inch handles 2500PSI, with galvanized variants resisting corrosion in farm/field environments. Its threads (11.5 TPI for NPT) ensure a tight seal with 1 inch pipes, compatible with "SZ" Brand tees and valves. A 2020 order for a Middle Eastern oilfield saw 10,000+ units deployed, with zero leaks reported—reinforcing its reliability in harsh conditions.
