AI-Powered supplier vetting

SummaryZhangjiagang Chewit is a China-based limited trading company established in 2010, with stated precision-tube and steel-forging manufacturing activities. The supplier reports ISO9001:2015 certification, more than 10 production lines, approximately 5,000 tons of annual seamless-steel-pipe productivity, broad export-market coverage, and one-month lead times in both peak and off-peak seasons. Its quality claims include 100% dimensional and surface checks, batch chemical and mechanical testing, and non-destructive testing upon request. Evidence is insufficient to assess after-sales service, financial credibility, and customization capability. Innovation evidence is limited to an associated forging operation reporting 11 authorized patents, while customer evidence consists of one listed buyer and one trade transaction.

Supplier typeThe supplier is identified as a China-based limited company and trade company, with stated manufacturing activities in precision steel tubes and forgings. Its product scope includes seamless, welded, carbon, stainless, hydraulic, cold-drawn, and precision tubes, indicating a specialized steel-product supplier with both trading and manufacturing positioning.

CertificationsThe supplier explicitly reports an ISO9001:2015 management-system certificate. It also describes inspection and industry-related qualifications associated with its forging operation, including API 20B, PED, and classification-society credentials, although the scope and holder of each qualification are not separately specified.

R&D capabilityThe supplier describes advanced production and inspection equipment, precision-tube manufacturing, and a forging operation with 11 authorized patents, including three invention patents. These statements provide explicit but limited evidence of process and product-development capability, mainly linked to the forging operation rather than clearly to the entire supplier entity.

Production capacityThe supplier reports more than 10 production lines, annual seamless-steel-pipe productivity of 5,000 tons, heat-treatment furnaces, inspection equipment, and manufacturing of precision tubes and forgings. The descriptions also cite a 10,000-square-meter tube operation and a substantially larger forging facility, although employee and facility figures are inconsistent across slices and should be verified.

Client casesThe supplier states that it serves wind power, oil and gas, transportation, shipbuilding, and gearbox sectors and has entered the global purchasing system of a major company since 2006. The trade data identifies one buyer and one transaction, so sector references are available but the breadth and depth of verifiable customer cases remain limited.

Product Q&A

Q:What is the tolerance for the stainless steel pipe?

The tolerance can be controlled at +/-0.05mm for OD and ID, with a minimum tolerance of +/-0.02mm available upon request.

Q:What are the available outer diameter and wall thickness ranges?

The outer diameter (OD) ranges from 1mm to 250mm, and the wall thickness (WT) ranges from 0.05mm to 50mm.

Q:Is the tube suitable for bending and flaring?

Yes, the tube has good mechanical performance due to sophisticated bright annealing technology, allowing it to be flared, flattened, and bent freely.

Q:What industries can this pipe be used for?

It is widely used in hydraulic/automotive pipes, laboratory gas, food/beverage, pharmaceutical, semiconductor, chemical industry, and heat exchangers.

Q:What delivery conditions are available?

Available delivery conditions include AP, BA, CFA, and CFP, depending on the specific application requirements.
