Key features

Each steel pipe is tested at 15kg pressure for 15 seconds before shipment. No sampling-every single pipe is verified leak-free, giving you complete confidence in the product.

Cover automotive exhaust (aluminized), decorative handrails (304 welded), chemical heat exchangers (316L seamless), and offshore platforms (2205) from a single steel pipe supplier.

Small diameter steel pipes are nested inside larger ones to maximize container space. This reduces your per-unit freight cost and simplifies warehouse receiving.

AI-Powered supplier vetting

SummaryCNB NEW MATERIAL (TIANJIN) CO., LTD. is a China-based trading company established in 2023 with three employees. It reports quality assurance, raw-material traceability, written inspection instructions, in-stock capability, and customization from samples or designs. The company states that 90% of sales are exports and cites international companies as fixed raw-material customers, although no specific case details are provided. Service reach is limited: it reports no overseas agents or branches, overseas warehouses, overseas showroom, offline trade-show participation, or overseas service countries. R&D evidence is weak, with no new product information in the past year, no ODM, no SDK, and no branded OEM capability. Financial information provided shows zero operating revenue and zero profit-related figures for the stated periods, requiring caution. Outsourcing procedures, manufacturing-capacity contracts, corrective-action records, complaint-handling records, and supplier-assessment records are incomplete or...

Financial creditThe submitted financial slices report zero operating revenue and zero profit-related figures for the stated periods, while current ratios are also reported as zero. These figures do not demonstrate financial strength and indicate a material need for verification before relying on the supplier’s financial capacity.

R&D capabilityThe supplier reports no new product information during the past year, no ODM service, and no available SDK. Although it can customize from samples and designs, the provided evidence does not support strong independent R&D or innovation capability.

Customization capabilityCustomization from samples and customization from designs are explicitly available through both design services and R&D-related services. This supports the supplier’s ability to handle customer-specific requirements, although no evidence is provided regarding production scale or technical complexity.

Client casesThe supplier states that it has become a fixed raw-material supplier to Panasonic, Toyota, Honda, IKEA, and Komatsu, and reports that 90% of total sales are exports. These named customer claims provide positive case evidence, but the slices do not include order scope, duration, product details, or independently verifiable references.

Product Q&A

Q:What is the difference between a welded and a seamless steel pipe?

Welded steel pipe is formed from flat strip and joined by argon arc or plasma welding along the longitudinal seam. It is cost-effective and ideal for structural, decorative, and low-to-medium pressure applications. Seamless steel pipe is produced from a solid billet by piercing and cold drawing, with no weld seam, providing superior pressure integrity for heat exchangers, boilers, and high-pressure instrumentation.

Q:Can your aluminized steel pipes be used for hot exhaust applications above 500 degrees Celsius?

Our aluminized steel pipes with DX53D+AS coating are rated for continuous service up to 550 degrees Celsius with minimal surface change. For intermittent exposure up to 650 degrees Celsius, the aluminized coating provides adequate protection. For sustained temperatures above 650 degrees Celsius, we recommend AISI 409 or 321 stainless steel pipes.

Q:Do you provide steel pipes with specific end finishes like beveled, grooved, or threaded?

Yes, we offer beveled ends for butt welding, grooved ends for couplings, and threaded ends per BSP or NPT standards. Flaring (up to 30%) is available for aluminized steel pipes used in exhaust connections. Specify your end preparation requirement when ordering your steel pipes.
