Public profile · Not claimed
Dalian Yuxing Water Treatment Equipment Co., Ltd. · Dalian, Liaoning, China

Dalian Yuxing Water Treatment Equipment is presented as a source-reviewed supplier profile centered on FRP Membrane Housings, with company-published capability 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.

Company overview

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.

Products & services summary

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.

SOURCE-REVIEWED PROCUREMENT PROFILE

How to evaluate Dalian Yuxing Water Treatment Equipment Co., Ltd. for FRP Membrane Housings

Evaluate Dalian Yuxing Water Treatment Equipment Co., Ltd. as a potential composite product manufacturer for MEMSHELL 8-inch FRP pressure vessels for RO membrane systems, verify the public evidence and prepare a comparable RFQ.

Published product scope, translated into buying checks

MEMSHELL 8-inch FRP pressure vessels for RO membrane systems

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.

MEMSHELL 4-inch FRP housings for RO, ultrafiltration and low-pressure membranes

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.

MEMSHELL 2.5-inch FRP membrane housings

This product broadens the supplier's public portfolio, but GetFRP does not infer approval from a product name alone. Ask Dalian Yuxing Water Treatment Equipment Co., Ltd. for the grade or model designation, manufacturing route, current technical file, production and test location, batch traceability and the limits that apply to published performance values.

Manufacturing and service capability review

FRP pressure-vessel design and manufacture for membrane systems

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.

Filament winding and structural molding of FRP membrane housings

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.

End-port, side-port and multi-port membrane-housing configurations

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.

Application fit to evaluate

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.

RO, ultrafiltration and desalination pressure-vessel systems

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.

Communication radomes and radio-transparent structures

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.

Composite utility and electrical infrastructure

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.

Supplier qualification checks

Freeze the drawing revision, material system, critical dimensions and acceptance tests before comparing quotations.
Identify the actual production site and distinguish in-house manufacturing from subcontracted tooling, finishing, testing or assembly.
Request a representative sample or first article made with the proposed production material and process.
Tie mechanical, fire, corrosion or electrical claims to the offered construction, thickness and test specimen.
Define visual limits, repair rules, traceability and the inspection sampling plan in measurable terms.
Review export packing, loading support, moisture protection and handling for the actual part geometry.

What to include in an RFQ

  1. 1Product definition: identify the requested MEMSHELL 8-inch FRP pressure vessels for RO membrane systems, drawing or grade revision, dimensions, material construction, quantity and expected annual demand.
  2. 2Performance: state the loads, environment, temperature, chemical, fire, electrical, appearance or service-life requirements that actually control selection.
  3. 3Process and source: ask whether FRP pressure-vessel design and manufacture for membrane systems is performed by Dalian Yuxing Water Treatment Equipment Co., Ltd. at the named production site and disclose subcontracted stages.
  4. 4Standards and evidence: name the required standard edition, test methods, report scope, laboratory or witness expectation and acceptance values.
  5. 5Quality plan: define the approved sample, incoming-material records, in-process controls, final inspection, sampling level, traceability and treatment of nonconforming product.
  6. 6Commercial boundary: request tooling or setup, MOQ, lead time, payment, warranty, Incoterm, export documents, packing dimensions and responsibility for transport damage as separate items.
  7. 7Change control: require written approval before changes to material, formulation, reinforcement, production site, tooling, critical process, specification or certificate status.

Evidence and review scope

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.
