FISCA Delegation visited PANDAPIPE’s Tianjin facility to review Fire Pipe manufacturing and laboratory testing. The visit showed how specifications, production checks and inspection records connect before shipment.
On September 8, 2026, PANDAPIPE welcomed a delegation from FISCA to our Tianjin manufacturing facility. The visit focused on Fire Pipe production, laboratory testing and the checks that connect a customer’s specification with the finished product.
For PANDAPIPE, the purpose of the visit was straightforward: show what buyers can verify inside a factory. The discussion covered production controls, pipe dimensions, testing, identification and the documents required before shipment.
From a Fire Pipe Specification to a Production Order
A Fire Pipe order normally begins with a standard, size list or bill of quantities. Before production, however, the factory still needs to confirm how those requirements will be applied.
Our team discussed the information required for a workable order, including pipe standard, NPS or DN, wall thickness, length, surface finish and end preparation. Approval and inspection requirements also need to be stated clearly.
Buyers can review PANDAPIPE’s available fire protection pipe specifications before preparing an RFQ.
Missing specifications can lead to different quotations for products that appear similar on paper. Confirming these details early gives the buyer, manufacturer and installation contractor the same reference point.
What FISCA Saw in the Production Workshop
The FISCA delegation visited the workshop to observe how steel pipes move through the manufacturing process.
Forming, Welding and Sizing
For ERW steel pipe production, steel strip is prepared, formed into a circular section and welded along the longitudinal seam. The pipe then passes through sizing and straightening operations.
During production, measurable characteristics include outside diameter, wall thickness, length, straightness and surface condition. These checks help determine whether the finished pipe matches the requirements written into the order.
The delegation also discussed the importance of pipe-end preparation. Plain, beveled, threaded and grooved ends serve different connection methods. The specified end must suit the pipe dimensions, wall thickness and fittings selected for the system.
Why “ASTM A795 + Grooved Ends” May Not Be Enough
| What the RFQ Says | What May Still Be Missing | What We Ask the Buyer to Confirm |
|---|---|---|
| ASTM A795 + Grooved Ends | Groove type | For light-weight (Sch 10) pipe, confirm rolled groove requirements. For standard-weight (Sch 40) pipe, confirm whether rolled or cut groove is required. |
| ASTM A795 + Grooved Ends | Groove dimensions | Provide the applicable grooving standard, coupling specification or approved drawing, including groove width, depth, groove diameter and distance from the pipe end where applicable. |
| Galvanized Pipe + Grooved Ends | Acceptance after grooving | Confirm project requirements for coating condition, burrs, pipe-end deformation and ovality after grooving. |
| Grooved Fire Pipe | Testing after grooving | Confirm whether hydrostatic testing or other inspection is required after groove processing. |
In actual Fire Pipe orders, “ASTM A795 + grooved ends” may not provide enough information to start production. ASTM A795 does not define all groove dimensions or every acceptance requirement after grooving. Based on our order experience, PANDAPIPE asks the buyer to provide the applicable grooving standard, coupling specification or approved drawing before production. This helps both sides confirm the pipe-end requirements before manufacturing and reduces the risk of dimensional or acceptance disputes when the pipes arrive on site.
Surface Finish and Marking
Black, painted and galvanized surfaces may be required for different fire protection projects. The purchase specification should state the required finish rather than relying on pipe colour as the only description.
Marking is equally practical. It helps receiving teams identify the standard, size and production information associated with each bundle. This becomes particularly useful when one shipment contains several diameters or batches.
Moving From the Workshop to the Laboratory
The laboratory visit allowed the discussion to move from visible manufacturing steps to recorded inspection evidence.
FISCA members learned about metallographic examination and its role in reviewing the material structure and weld area. Depending on the applicable standard and purchase order, inspection may also cover chemical composition, mechanical properties, dimensional tolerances, flattening performance and leak integrity.
For orders produced to ASTM A795, buyers should confirm the pipe type, grade, dimensions and required testing route. ASTM A795/A795M covers black and galvanized welded and seamless steel pipe intended for fire protection use.
The standard provides for hydrostatic testing, with nondestructive electric testing permitted as an alternative under its specified conditions. PANDAPIPE’s guide to pipe pressure testing explains the difference between factory testing, system testing and project acceptance.
A test report is useful only when it can be matched to the supplied product and purchase requirement.
Checking UL and FM Requirements Before Ordering
Some projects call for UL Listed Fire Pipe, while others specify FM Approved Fire Pipe.
These are separate requirements. Buyers should verify that the manufacturer, product type and ordered size range are included in the applicable listing or approval record.
A certificate displayed in a catalogue does not automatically cover every size, wall thickness, connection or finish. The approval scope should be checked against the BOQ before the order is confirmed.
The FISCA visit was a technical exchange and factory tour. It was not a new certification, product approval or purchasing commitment.
A Practical Fire Pipe Order Checklist
Before releasing a purchase order, buyers should confirm:
- Product standard and material grade;
- NPS, DN and outside diameter;
- Wall thickness or pipe schedule;
- Pipe length and ordered quantity;
- Surface finish and end preparation;
- UL, FM or third-party inspection requirements;
- Mill test certificates and inspection reports;
- Marking, packing and delivery requirements.
This checklist gives both sides a clear basis for production and final inspection.
What Buyers Actually Review Before Choosing a Supplier
Price is not always the final deciding factor in a Fire Pipe order. In one customer evaluation, PANDAPIPE was not the lowest-priced supplier, but the buyer requested additional evidence before making the decision.
We provided product samples, previous third-party inspection records, hydrostatic test records, coating inspection records, groove inspection records, documentation and a proposed delivery schedule. We also shared records from previous project supply.
For buyers, these materials provide something more useful than a general statement about “good quality”: they allow procurement and engineering teams to review what was actually inspected, documented and delivered on previous orders.
Our continued supply experience for the ARADA real estate project also provided a relevant reference for customers evaluating PANDAPIPE for Middle East projects.
Turning Factory Visits Into Clearer Project Requirements
We thank the FISCA delegation for visiting our production workshop and laboratory. At the end of the tour, guests received Steel Pipe Insider certificates as a record of the visit.
PANDAPIPE manufactures and supplies welded and seamless steel pipe for fire protection and industrial projects. Our team can support specification review, pipe processing, surface treatment, inspection coordination and export documentation.
Planning a Fire Pipe order? Send PANDAPIPE your specification or BOQ, including the required standard, sizes, approvals and destination. We will review the details and prepare a project-based Fire Pipe quotation.

No. The visit was a technical exchange and factory tour. It should not be described as a certification, approval, endorsement or purchasing commitment.
3. What Did the Delegation See in the Workshop?
The delegation reviewed the production environment and discussed forming, welding, sizing, dimensional control, surface finish and pipe-end preparation.
4. Which Standard Is Commonly Used for Fire Pipe?
ASTM A795/A795M is intended specifically for black and galvanized welded or seamless steel pipe used in fire protection systems. Some projects may specify ASTM A53 or ASTM A135.
5. What Tests May Apply to Fire Pipe?
Depending on the standard and order, testing may include chemical analysis, mechanical testing, flattening tests, dimensional inspection, hydrostatic testing or nondestructive electric testing.
