Dalian Yuxing Water Treatment Equipment is a source-reviewed supplier profile for pultruded, with every search topic tied to company-published product or process evidence and separated from buyer-side verification requirements.
Dalian Yuxing Water Treatment Equipment Co., Ltd. (also written on its website as Dalian Yuxing Water Purification Equipment Co., Ltd.; MEMSHELL / Mem shell) is a mainland-China manufacturer of FRP membrane housings and composite tubular products in Lushunkou District, Dalian, Liaoning. The current site title, Chinese footer, ICP filing and Dalian contacts use the shorter Chinese legal identity, while the company text uses the extended variant for the same business established in February 1998. The memshell.com.cn registrant, company-domain emails and MEMSHELL product brand connect the variants. China Composites Expo lists DALIAN YUXING WATER TREATMENT EQUIPMENT CO., LTD. and describes FRP membrane-separation pressure vessels, thermoset and thermoplastic pressure pipe, composite utility poles and thermoplastic composite panels; the current Shenzhen exhibition directory uses the shorter Chinese identity. The Chinese variants, English exhibition name, MEMSHELL brand, domain and Beijing sales office are deduplicated to this one Dalian mainland entity. Unrelated Yuxing companies are excluded. The site is accessible over HTTP and contains page assets updated in 2023, but HTTPS did not establish a connection during the 2026-08-13 review.
The reviewed product and process scope makes this supplier relevant to buyer searches for pultruded. These phrases describe products or processes supported by the cited public scope; they do not expand the supplier's catalog or replace technical qualification.

This procurement profile is built for engineering and procurement teams comparing a finished FRP or composite component against a controlled drawing, service condition and inspection plan. It organizes Dalian Yuxing Water Treatment Equipment Co., Ltd.'s published products, processes, certificate references and official sources around the primary topic “Dalian Yuxing Water Treatment Equipment FRP Membrane Housings.” The objective is to help a buyer decide whether to open a controlled RFQ, not to turn a broad company catalog into an unsupported approval.
Dalian Yuxing Water Treatment Equipment Co., Ltd. currently lists 8 product or service groups and 8 manufacturing or support capabilities in this reviewed record. The public scope indicates what to investigate, while the buyer remains responsible for drawings, design calculations, standards, current certificates, sample approval and order-specific commercial confirmation. Claims below are attributed to the attached source set unless GetFRP explicitly labels them as qualification guidance.
Yuxing's central sourcing scope is the MEMSHELL FRP pressure vessel for membrane systems. Its site publishes end-, side- and multi-port arrangements, 75–1800 psi, 2.5-, 4- and 8-inch diameters and one to seven membrane elements. Treat these as series statements, not approval of every combination. Lock model, membrane, pressure, temperature, media, cleaning chemistry, ports, end assembly, seals, supports and cyclic duty. Require design basis, rated/test pressure, burst and fatigue evidence, leak/hydrostatic tests, construction, cure and lot records, instructions, spares and life limits. Desalination, chemicals or drinking-water service needs specific compatibility and destination approval. Other published products include pressure pipe, radomes, rocket shells and utility structures; each needs its own controlled drawing and test plan. The qualification page shows an ISO 9001:2015 certificate issued in 2016 whose pictured validity has ended, plus older credentials. No reviewed page establishes a current 2026 certificate or hygienic permit, so none is recorded. Published export markets, an English site and company-domain email support an initial export-ready flag; verify a recent shipment, exporter, destination rules, documents, packing and service. The site currently works only over unencrypted HTTP. Independently verify email, payee and bank details. All claims require current documents, tests, audit and representative-order evidence.
No company-level certification is listed on this profile.
Evaluate Dalian Yuxing Water Treatment Equipment Co., Ltd. as a potential composite product manufacturer for pultruded, verify the public evidence and prepare a comparable RFQ.
Dalian Yuxing Water Treatment Equipment Co., Ltd. includes this product in its published supply scope. Treat that listing as a starting point: request the current datasheet or drawing, material and construction, available grades or dimensions, guaranteed properties, production site, quotation revision and evidence that represents the exact item offered.
For MEMSHELL 4-inch FRP housings for RO, ultrafiltration and low-pressure membranes, buyers should convert the catalog description into an acceptance specification. Confirm standard and custom options, raw-material system, critical tolerances, surface or finish, test basis, sample route, MOQ, lead time and packing. Any alternative proposed by Dalian Yuxing Water Treatment Equipment Co., Ltd. should be identified explicitly rather than treated as automatically equivalent.
Dalian Yuxing Water Treatment Equipment Co., Ltd. publishes FRP pressure-vessel design and manufacture for membrane systems as part of its capability scope. Buyers should ask which site and equipment perform the work, the practical size or material limits, the normal control records and whether the proposed order uses the same route. Subcontracted stages should be visible in the quality plan.
The relevance of Filament winding and structural molding of FRP membrane housings depends on the requested product and acceptance criteria. During qualification, request a process flow, critical control points, inspection or test method, operator or equipment qualification where applicable, nonconformance handling and a recent example that represents the offered production route.
For sourcing purposes, End-port, side-port and multi-port membrane-housing configurations is a capability signal rather than independent verification. Confirm capacity, tooling or fixture availability, setup and changeover assumptions, lot definition, sample approval and traceability. The quotation should identify any limitation that could affect geometry, performance, appearance or delivery.
These are sourcing contexts suggested by the published product scope, not confirmed project references. Validate the exact application, design basis and evidence in the RFQ.
Dalian Yuxing Water Treatment Equipment Co., Ltd.: Membrane-housing qualification should lock model, membrane count, port arrangement, pressure, temperature, media, cleaning chemistry, end assembly, seals, supports and cyclic duty. Require design basis, pressure and leak testing, burst and fatigue evidence, material traceability, installation instructions, spares and destination-specific pressure or drinking-water approvals for the exact housing offered.
Dalian Yuxing Water Treatment Equipment Co., Ltd.: A radome RFQ should define frequency bands, transmission loss, reflection, dielectric properties, antenna clearance, section drawing, material, finish, wind and ice loads, UV and weather exposure, mounting, drainage and dimensional tolerance. Require representative radio-frequency, mechanical and environmental test evidence for the offered construction rather than a generic material statement.
Dalian Yuxing Water Treatment Equipment Co., Ltd.: Utility poles, crossarms and insulation structures need a controlled design basis covering geometry, load cases, deflection, connection details, electrical insulation, tracking and erosion, fire, UV, moisture, temperature, fatigue and installation. Buyers should identify the governing utility or railway specification and require type, routine and lot evidence for the exact product family.
Dalian Yuxing Water Treatment Equipment Co., Ltd.'s source record currently includes Official Dalian Yuxing English Website, Official Yuxing Company Profile, Official Yuxing Product Directory, Official MEMSHELL 8-inch Model Table. These links let a buyer distinguish company-published information from GetFRP's own qualification guidance and return to the original context when a claim changes.
No company-level certification is presently listed in the reviewed profile. That does not prove that no document exists, but it means the RFQ should ask for the quality-system certificate and every product-specific test or approval needed by the buyer rather than assuming a certification from market reputation.
GetFRP last recorded a public-source review date of 2026-08-13. Public websites and catalogs can change after review, so commercial decisions should use newly downloaded files and direct supplier confirmation. GetFRP's public or claimed status describes profile ownership and identity controls; it does not certify every product statement or predict order performance.

According to its official website, F1 Composites is FengDu New Material's international export company. It supplies pultruded FRP profiles, gratings, fiberglass window and door systems, and custom pultrusions for overseas projects, with English-language engineering, quality documentation, export coordination and international delivery support.
Jiangsu Aosheng Composite Materials Technology Co., Ltd. is a Suzhou-based carbon-composite company whose current corporate website and 2026 China Composites Expo listing support carbon-fiber woven and hybrid fabrics, prepreg, wind-blade pultruded plate and composite application development. The official site also presents automotive, sports, hydrogen, aviation and overseas footprints under the Aosheng group. GetFRP therefore assigns measured-demand phrases such as carbon fiber fabric, carbon fiber plate, pultruded, resin infusion and vacuum infusion only where a published product or manufacturing route supports them. Fishing rods may be an end use of prepreg, but they are not listed here as an Aosheng finished product. Likewise, automotive parts, sports products and hydrogen cylinders are marked as group-sector inquiries rather than automatically attributed to the Jiangsu parent factory. Buyers must confirm the exact legal entity, production site and specification behind a quotation. Awards, customer relationships, capacity, CNAS, patent and standards-participation statements on the website remain company claims, not GetFRP verification.
Nanjing Hitech Composites Co., Ltd. publishes an integrated HICOMA and Lica offer spanning pultruded carbon- and glass-fiber profiles, high-performance reinforcement fabrics and structural adhesives. Its current official catalog explicitly lists carbon-fiber plate, rod, tube, channel, rebar and prestressed plate systems; fiberglass beams, channels, angles, tubes, plates, rebar and grating; carbon- and glass-fiber fabrics; and bonding products for wind blades, carbon plate and civil structures. The China Composites Expo directory independently supports the Nanjing exhibitor identity and its pultruded-composite and epoxy-adhesive scope. GetFRP therefore assigns only demand phrases supported by those actual products, including carbon-fiber products, plates, rods, tubes and fabrics, pultruded fiberglass profiles and fiberglass grating. An application, system or performance label is not treated as a substitute for the offered grade, section drawing, laminate architecture, adhesive TDS or project engineering.
