SummaryShandong Shengxin Pipe Industry Co., Ltd. is a China-based limited company established in 2013, focused on grooved fittings and couplings. The provided information describes casting and coating production capabilities, a stated annual capacity of 100,000 tons, a 16,922 m² manufacturing plant, DISA and other casting lines, and multiple electric furnaces. It reports CE certification, FM certification, and additional testing or certification activity. The supplier states that it operates an R&D center, has a quality-testing laboratory, and provides OEM service. Export activity began in 2021, with exports representing 41%–50% of total sales and goods exported through both agency and self-operated channels. Evidence is insufficient to confirm after-sales service systems, financial credibility, or specific customer cases. Employee information is inconsistent across the slices, with one source stating 49 employees and another stating more than 300, so workforce scale should be verified.
Supplier typeThe supplier is identified as Shandong Shengxin Pipe Industry Co., Ltd., a Chinese limited company in Shandong. Its descriptions identify it as a modern enterprise researching and producing grooved fittings and couplings, while another record classifies the company as a trading company and reports combined business status; it also has stated manufacturing facilities and production equipment.
CertificationsThe supplier explicitly reports CE certification in 2016 and FM certification in 2017. It also states that it applied for Korean KC certification and passed the BS6920 test in the UK through the Hong Kong Water Supplies Department in 2021; these latter statements indicate testing or certification activity but do not establish the current status of every certification.
R&D capabilityThe supplier states that it has an R&D center, a unique R&D department, a quality-testing laboratory, and a Weifang industrial-enterprise technology R&D program. It also reports newly developed energy-saving smelting equipment and adoption of Danish DISA casting technology, supporting an established technical-development capability.
Production capacityThe supplier reports annual grooved fittings and couplings productivity of 100,000 tons, a plastic coating production line with annual capacity above 100,000 tons, a 16,922 m² manufacturing plant, one Danish DISA casting line, one additional casting line, and five medium-frequency electric furnaces. These details provide explicit evidence of substantial production infrastructure, although the stated employee counts are inconsistent between sources.
Customization capabilityThe supplier explicitly states that its R&D and quality-testing facilities provide OEM service. The product information also lists multiple branch-starter and fitting size combinations, but the slices do not specify the scope, engineering process, tooling capability, or minimum requirements for customized products.
