SummaryWenzhou Zhenghai Sealing Co., Ltd is identified as a China-based manufacturer/factory in Zhejiang, producing metallic ring gaskets, flange gaskets, spiral-wound gaskets, and related sealing products. The supplier reports CNC and inspection equipment, 10 production lines, and 6–10 quality-control staff. It states that products can be made to customer drawings and dimensions, with a maximum product size of 2,000 mm, and lists multiple management-system certifications, including ISO 9001 and API-related certifications. Export activity reportedly began in 2023, while export sales represent 1%–10% of total sales. Evidence is insufficient to assess after-sales capability, financial credibility, innovation capability, or customer cases.
Supplier typeThe supplier is explicitly classified as a Manufacturer/Factory, while another record describes the company nature as a trade company. The formal supplier-type field and the company’s stated manufacturing address support manufacturer status, although the conflicting classification should be clarified.
CertificationsThe supplier states that it passed API 6A, API Q1, and ISO 9001:2008 certifications, and separately lists ISO 9000, ISO 9001, ISO 14001, ISO 14000, and ISO 50001 management-system certifications. These declarations provide explicit evidence of certification holding, although certificate validity and scope are not supplied.
Production capacityProduction capability is supported by 10 production lines, 6–10 quality-control staff, CNC and testing equipment, a stated maximum product size of 2,000 mm, and a broad range of gasket products and materials. The supplier also identifies specialized ring-joint and flange-gasket applications, indicating established product manufacturing scope.
Customization capabilityThe supplier explicitly states that it can manufacture according to customer-specific dimensions or drawings, with products up to 2,000 mm, and can supply products in approximately 30 material types. This directly supports customization in dimensions, drawings, and material selection.
Product Q&A
Q:What is the maximum pressure rating for BX type gaskets?
A:
BX type metal ring gaskets can be used at pressures up to 20,000 psi.
Q:How does the RX type gasket achieve sealing?
A:
It establishes an initial seal through axial compression and plastic deformation, then uses medium pressure for radial expansion to tighten the seal.
Q:What is the material composition of these gaskets?
A:
The gaskets are made of metal material processed through forging, heat treatment, and machining.
Q:What is the function of the pressure passage hole in BX gaskets?
A:
The pressure passage hole allows for pressure equalization on each side of the sealing faces.
Q:What types of metal ring gaskets are available?
A:
We offer RX, BX, and R series metal ring gaskets, including octagonal and oval shapes.
