In the realm of fluid dynamics and industrial structural engineering, the Stainless Steel 5 Inch Pipe (approximately 127mm Outer Diameter) represents a critical specification. Often utilized in heavy-duty applications where standard 4-inch pipes lack volume capacity and 6-inch pipes exceed space constraints, the 5-inch variant is a masterpiece of hydraulic efficiency. Our manufacturing process focuses on AISI 304, 304L, 316, and 316L grades, ensuring maximum resistance to intergranular corrosion and oxidative stress.
Our 5-inch pipes maintain a wall thickness tolerance of ±10%, adhering to ASTM A312 standards for seamless and welded configurations. This precision is vital for high-pressure gas transportation and sensitive chemical processing.
Utilizing high chromium and nickel content, our pipes are designed to withstand chloride-rich environments, making them ideal for offshore platforms and desalination plants.
With an ability to maintain structural integrity from cryogenic temperatures up to 870°C, Shaanxi Kerlimar's pipes are the gold standard for thermal control solutions.
Established in 2003, Shaanxi Kerlimar Engineers Co., Ltd. has evolved from a local pipe manufacturer into a global powerhouse of pipeline solutions. Our chairman, Mr. Ming SUN, an advocate for climate change action, has steered the company towards sustainable innovation.
Winning the National High-tech Enterprise certification in 2020, we don't just manufacture; we innovate. Our work in vertical axis wind power technology and grid structures informs our metallurgy, resulting in stronger, lighter, and more durable stainless steel pipes.
From the China-Finland High Technology Match Conference to the Dubai COP28 Conference, our brand is recognized globally for its commitment to "Double Carbon" goals and engineering excellence.
Shaanxi Kerlimar Engineers Co., Ltd. was established in 2003, has long been engaged in international trade business, mainly a variety of pipes, carbon steel, alloy steel, stainless steel material, seamless pipe, straight seam welded pipe, spiral welded pipe and matching pipe fittings. Manufacturing standards for ASTM, ASME, EN, JIS and so on, in line with international standards. We are providing good quality, price competition, timely delivery, perfect service!
Company Culture: The chairman of the company: Mr. Ming SUN, is a strong environmentalist and a fan of technological innovation. Since 2019, focus on the new vertical axis wind power technology research and development... More than 40 patents have been authorized by the State Intellectual Property Office.
In December 2020, we won the national High-tech Enterprise certification, in June 2021, we were invited to participate in the China-Finland High Technology Match Conference... In December 2023, we were invited to participate in the Dubai COP28 Conference. We are currently completed 10KW-500KW series of small units before landing experiment...
Strategically located in Shaanxi, we leverage China's vast high-speed rail and maritime network to ensure that 5-inch pipe orders reach European, American, and Southeast Asian ports with reduced lead times.
We provide full documentation, including Material Test Reports (MTRs), EN 10204 3.1/3.2 certifications, and third-party inspection reports (SGS, TUV) to meet local regulatory requirements in the EU and USA.
By integrating upstream raw material sourcing with advanced automated welding, we offer a 15-20% cost advantage over local manufacturers without compromising on "Zero-Defect" quality standards.
For global enterprises, we offer customized wall thicknesses (Schedule 5s to XXS) and localized finishing (Polished, Pickled, or Sandblasted) to meet specific regional application scenarios, from pharmaceutical cleanrooms in Switzerland to oil refineries in the Middle East.
The stainless steel pipe industry is undergoing a digital and green transformation. As a growth-focused manufacturer, Shaanxi Kerlimar is at the forefront of these shifts:
Seamless pipes are extruded from a solid billet, offering higher pressure ratings and uniformity, ideal for extreme environments. Welded pipes are formed from strips and are more cost-effective for structural and moderate pressure applications. Both are manufactured to ASTM A312 at our factory.
Yes. We produce high-purity 316L stainless steel pipes with Ra < 0.8μm internal surface roughness, specifically designed for dairy, beverage, and pharmaceutical industries, ensuring no bacterial growth or product contamination.
We manage the entire export process, including DAP/DDP terms for many regions. All products come with full traceability documentation and comply with ASME B36.19 and B36.10 standards to ensure seamless integration into your local projects.
For standard specifications, our lead time is typically 15-20 days. Custom orders or large-scale project requirements may take 30-45 days, depending on the material grade and certifications required.
