One factory, every stage

Luquantun Town Development Zone, Wucheng County, Dezhou City, Shandong Province. Dezhou sits on the Beijing to Shanghai corridor, which is why export orders route out through Tianjin or Qingdao. It is one site: the design office, three production lines, the inspection bay and the packing area are all in the same 11,000 square metre building, and the address on our documents is the address where the tanks are pressed.

11,000 square metres across five areas with one direction of travel. Raw material comes in at receiving, moves through cutting and pressing, then punching and forming, then assembly and inspection, then packing. Material never doubles back, which is what keeps a part from being pressed twice or shipped unchecked. Three production lines run in parallel so a stainless order does not queue behind a galvanized one.

Around 25, covering hydraulic panel presses, shearing and cutting lines, punching lines, roll forming, argon arc welding stations for stainless, and the hot press used for SMC. The SMC press runs at roughly 145 degrees Celsius and 9 MPa for about nine minutes per panel, which is what gives a GRP panel its finished strength and surface. The equipment list is in the company profile.

Yes, and buyers do. Tell us roughly when and what you want to see and we will arrange it around the production schedule, because watching a press run is more useful than walking an empty line. Requests go through the form on this page or the contact page. If travel is not practical, this virtual tour follows exactly the same route.

Yes. Nominate an inspection house and we will write their hold points into the production order. The standard inspection and test plan already covers material receipt, pressing, dimensional check against the approved drawing, assembly and the hydrostatic test before dispatch. Agree witness points before the drawing is approved so they are scheduled rather than squeezed in. ITP templates are on the technical support page.

A drawing. Nothing is cut until you have approved a general arrangement showing panel layout, thicknesses by course, nozzle and penetration positions, ladder and manhole placement and plinth centres. That approved drawing becomes the document inspection measures against. It is also the point where changes are cheap; after pressing they are not.

Every tank is checked against its drawing and then water tested. Panels are measured dimensionally, the assembly is checked for fit, and a hydrostatic test holds water in the tank to prove the joints and gasket compression before it is stripped, dried and packed. The test sheet travels with the tank. A tank that has not been water tested at the factory is a tank you are testing on your own site.

One crate, one tank. Panels, stiffeners, bolts and gaskets are kitted per tank and crated together so nothing arrives as a loose count that has to be reconciled on site. Flat packing is what allowed a 592 cubic metre order to travel in a sensible number of containers, and a twelve-tank village scheme to move in four. Everything ships through Tianjin or Qingdao.

All five: GRP/SMC, stainless steel, hot-dip galvanized, enameled steel and BDF underground. Because they share one building, a project that needs a GRP roof store and a galvanized ground reserve is still one supplier, one drawing set and one shipment.

Yes. ISO 9001 for quality management, ISO 14001 for environmental management and ISO 45001 for occupational health and safety, plus CE to EN 13280:2001 and five GB/T 17219 drinking water contact test reports. An SGS assessment was carried out on site rather than on paper. Every certificate is listed with its number on the certifications page; ISO 9001 is published by ISO.

They do, and it is deliberate. The design office is on the same site as the workshop, so a question from the floor reaches the person who drew the panel in minutes and a drawing revision reaches the press the same day. It is also why the engineering desk can promise a 2 hour first reply: the people answering are the people building.

Yes. The case studies cover twelve projects with the duty, the material, the capacity and the result, from a hospital fire reserve assembled in a 2.1 metre plant room to a twelve-tank village scheme. Datasheets and CAD files for every tank type are on the downloads page.

Everything on site is production, not display. The 11,000 square metre building holds three water tank production lines, a design office and an inspection bay, and the address on our certificates is this address. When you visit a water tank factory in China it is worth asking to see a press running and a water tank under hydrostatic test; both happen here on an ordinary working day.

Capacity is better measured in panels than in water tanks, because a 5 m3 water tank and a 500 m3 water tank are the same process at different counts. Three lines run in parallel so a stainless water tank order does not queue behind a galvanized one, and roughly 25 machines cover pressing, cutting, punching, forming and welding. Tell us your quantity and delivery date and we will answer against the actual schedule.

Receiving checks incoming material against its certificate. Cutting and pressing forms the water tank panels, with the SMC press running at about 145 degrees Celsius and 9 MPa for roughly nine minutes. Punching and forming adds the bolt pattern and penetrations. Assembly and inspection trial-builds and water tests the water tank. Packing crates it, one crate per water tank, for shipping through Tianjin or Qingdao.

Yes, if the timing works. Tell us when you can travel and we will schedule your water tank into that window where the production plan allows, so you see your own panels rather than someone else. If you cannot travel, we can send progress photographs at the hold points written into your inspection and test plan, agreed through technical support before the drawing is approved.

Common panel materials and standard fasteners are held so a straightforward water tank does not wait on procurement. Special grades, such as 316L for a high-chloride duty, are ordered against the job with their mill certificates. Purchasing sits in the same building as production, so a material query does not bounce between offices before it reaches the person who can answer it.

The water tank stops. Quality control reports separately from production and can hold a batch, so a non-conformance is recorded against the batch number the material arrived under and the panel is re-made rather than passed along. You are told if it affects your delivery date; you are not told afterwards.

Five ranges share the three lines: GRP/FRP/SMC, stainless steel, hot-dip galvanized, enameled steel and BDF underground water tanks, 13 models in each. The tour follows a GRP panel through the building, but a stainless or galvanized water tank takes the same route with a different press and finishing step. See all 65 models in the full catalogue.
