AI-Powered supplier vetting

SummaryFushun Bright Science and Technology Co., Ltd. is identified as a Chinese manufacturer specializing in petrochemical sampling equipment and accessories. The supplier reports ISO 9001:2015 certification, 10 production lines, stated annual production capacities across several sampler categories, and teams covering research, design, manufacturing, sales, and after-sales service. Its product applications span petrochemical and several other industries, while export activity began in 2015 and reportedly accounts for 11%–20% of total sales. Evidence supports established manufacturing and product specialization, but information is insufficient to confirm financial strength, customization capability, or specific customer cases. Some company details are inconsistent: one source states establishment in 2000, while another states 1996; employee counts also differ between 23 and more than 30.

Supplier typeThe supplier is explicitly classified as a manufacturer and describes itself as a professional manufacturer and exporter focused on petrochemical sampling equipment. Its stated product range includes sampling systems, cylinders, samplers, valves, and fittings.

CertificationsThe supplier reports holding an ISO 9001:2015 certificate and states that its products comply with international quality standards and regulations. The certification is explicit, although no scope, issuing body, or validity details are provided.

After-Sales capabilityThe company description explicitly identifies after-sales service as one of its organizational functions and claims quality control throughout design and manufacturing to support customer satisfaction. However, no detailed evidence is provided regarding service personnel, response procedures, warranties, or service coverage.

R&D capabilityThe supplier reports scientific research and design teams, five years of total R&D engineer experience, and involvement in the design and development of petrochemical sampling equipment. This supports the existence of R&D capability, but the slices provide no patents, new-product records, dedicated R&D scale, or technological achievements.

Production capacityThe supplier reports 10 production lines and stated annual capacities of 100,000 sets of LPG sample cylinders, 100,000 pieces of liquid petroleum products samplers, 10,000 pieces of other samplers, and 1,000 closed-loop sampling system points. It also reports facilities and manufacturing teams, providing explicit evidence of production capability.

Product Q&A

Q:What standards does this pressure hydrometer cylinder conform to?

The cylinder conforms to ASTM D1657, SH/T 0221, and ISO 3993 standards for testing the density or relative density of light hydrocarbons.

Q:What is the maximum working pressure for this device?

The working pressure is 1.4 MPa, making it suitable for testing LPG and light hydrocarbons with vapor pressures less than 1.4 MPa.

Q:What material is used for the cylinder body?

The cylinder is made of plexiglass (polymethylmethacrylate) or plastic, allowing for clear observation of the hydrometer and thermometer.

Q:What safety features are included?

The design includes a protective shield requirement, tight sealing with neoprene gaskets, and an integrated pressure gauge for monitoring inner tube pressure.

Q:What is the lead time for production?

The average lead time is within 15 workdays for both peak and off-season periods.
