Can I customize size, pressure and flange standard?

Yes. Volume, working pressure, tank size, flanges all support customization. Multi-tank parallel design is available for large flow projects.

Whats the advantage compared with traditional surge tower?

Our bladder tank is small and occupies much less space. No civil construction cost, no continuous air supply and lower long-term operation cost.

Can you help calculate the tank volume for my pipeline system?

Yes. Please provide pipe diameter, flow rate, pump power and working pressure.

AI-Powered supplier vetting

SummaryThe supplier is identified as a combined company with substantial manufacturing equipment, a 30,000-square-meter workshop, and stated lifting, machining, heat-treatment, and welding capabilities. It holds ISO9001, ISO14001, ISO45001, ASME U stamp, and NB certifications according to the company description, while another record specifically confirms ISO9001:2015. Service procedures for supplier assessment, corrective actions, and customer complaints are documented and followed, but no approved-supplier list is maintained. The supplier offers extensive customization and ODM services, although it reported no new products in the past year and no available SDK. Export activity is material, with 51%–70% of sales from exports, supported by experienced export staff, but it has no overseas warehouse, showroom, agent or branch, or offline trade-show participation. Financial credibility cannot be determined because the provided records contain only years, not financial results or indicators.

Supplier typeThe supplier is explicitly classified as a "Combined" company. The record also describes broad offerings spanning general information, export trade, manufacturing, service, quality control, R&D, and sustainability, supporting a diversified supplier profile.

CertificationsThe company description states possession of ISO9001, ISO14001, ISO45001, ASME U stamp, and NB certification; ISO9001:2015 is separately recorded as a management-system and sustainable-development certification. These records provide explicit evidence of multiple certifications, although the detailed description does not specify validity dates or scopes.

After-Sales capabilityThe supplier has documented and followed procedures for corrective and preventive actions and for handling customer complaints. However, it has no overseas warehouse, showroom, overseas agent or branch, and no offline trade-show participation, indicating limited stated overseas service infrastructure.

Production capacityThe supplier reports a 30,000-square-meter workshop, one production line, a 280-ton single-workshop lifting capacity, large bending and turning equipment, a heat-treatment furnace, and automatic welding machines. Finished-product inspection instructions are uniformly followed, but continuous quantity reconciliation for each batch or production volume is not performed.

Customization capabilityThe supplier explicitly provides customization from samples, designs, full customization, minor customization, and flexible customization through both design and R&D services. It also offers ODM service, demonstrating broad stated customization coverage.

Client casesThe supplier states that it provides OEM services for well-known brands and has collaborated with Fortune 500 companies. These are explicit customer-related credentials, although no customer names, project details, product scope, or performance outcomes are provided.

Product Q&A

Q:Do you have ASME certification?

Yes. Our tanks are manufactured per ASME Section VIII Div.1 with U-stamp. We can also provide PED/CE, CRN certificates as requested

Q:Whats the function of the bladder?

The bladder fully separates air and water. The tank shell will not touch water so no rust. If damaged, only replace the bladder instead of the whole tank.

Q:When should I use this tank?

It is widely used to eliminate water hammer for water supply pipeline, pump station, fire system, HVAC and chemical circulation pipes. It can prevent pipe burst and negative pressure collapse.

Q:Which tank materials are available

Standard SA-516 Gr70 carbon steel with anti-corrosion coating; 304 / 316L stainless steel for seawater and corrosive media.

Q:Vertical or horizontal installation?

Both installation types are available. Complete fittings like lifting lugs, pressure gauge, drain and air valve are equipped for easy installation.
