From 100% high-standard resin to pressure, temperature and dimensional testing, every Bekaatherm batch is controlled for consistency, so it won’t fail behind a wall. Backed by SKZ, ISO, CE and WRAS certification and 30+ years of manufacturing across a 120,000 m² plant.
We supply PPR, HDPE and UPVC systems wholesale to importers, distributors and contractors, not single-item retail.
Piping is concealed work. Once a PPR or PE line is behind a wall, in a floor slab, or underground, a burst joint or an under-spec wall doesn’t just leak, it means breaking open finished work, re-doing the install, and facing claims.
That’s why serious importers and contractors don’t buy on price alone; they buy on evidence of control. The three failures that cost buyers the most are the three we engineer against: under-rated pressure, understated wall thickness, and batch-to-batch drift in color and dimensions. A pipe that “meets PN25” on a label but was extruded from cheap regrind, or a fitting whose wall was thinned to save a few grams of resin, looks identical in the box, and only reveals itself once it’s fused into a live system. The rest of this page shows exactly how each risk is controlled, with parameters you can request and verify against a real batch.

Every experienced importer and project buyer carries the same three anxieties into a piping order. Here is what each one costs when it goes wrong, and the exact control point in our production that removes it, so the decision moves from “trust me” to “here is how.”
| Buyer’s core fear | What it costs on-site | Where Bekaatherm controls it | Proof you can request |
|---|---|---|---|
| Pressure not to rating → burst | Re-work, water damage, claims from the main contractor | Pressure & temperature testing to the rated PN class (PN20 / PN25) | Batch pressure test result |
| Understated wall thickness | Weak pipe, early fatigue, premature failure | 100% virgin resin + in-line dimensional control against the spec | Dimensional / wall-thickness report |
| Batch color / size drift | Mismatched building, rejected stock, lost reorders | Consistent masterbatch dosing + 10,000 in-house molds + in-line checks | Batch sample vs. approved reference |
| Non-conforming units in a container | Returns, sorting good stock from bad, brand damage | Pre-shipment sampling before goods leave the plant | Factory test report (on request) |

No amount of downstream testing fixes cheap raw material. Bekaatherm builds PPR and PE products from 100% high-standard resin, not regrind or filler, because virgin material is what delivers the real pressure rating, the true service life, and the clean-water safety that WRAS and SKZ demand.
Incoming material is verified before it enters production, so the pipe leaving our lines is made from what the spec sheet says it’s made from. This is the difference between a pipe that meets PN20/PN25 on paper and one that meets it in a wall for 30 years. The same raw-material discipline runs across the full range, plain PPR, aluminium-composite PPR-AL-PPR, fiberglass-composite PPR, HDPE / PP compression and UPVC drainage, so a buyer sourcing a matched system gets one consistent material standard, not a strong pipe paired with a weak fitting.
| Raw material | 100% high-standard resin (no regrind) |
| Product range covered | PPR PN20/PN25, PPR-AL-PPR, Fiberglass PPR, PE, UPVC drainage |
| Drinking-water safety | Aligned to WRAS / SKZ requirements |
| Brass inserts (fittings/valves) | Brass-core components for threaded & valve items |
| Material certificates | Available on request |
Quality isn’t a single inspection at the end, it’s a chain of checks, each catching what the last one couldn’t. Here is the path every Bekaatherm batch follows before it becomes your stock.
Incoming 100% high-standard resin verified before it enters production, no regrind, no filler.
Outer diameter and wall thickness monitored on the extrusion line so drift is caught early, not at the end.
PPR & PE run through pressure and hot/cold-water testing to confirm they hold their rated PN class.
OD and wall thickness measured against target spec across the 20–63 mm range, no understated wall.
Sampling before goods leave the plant; a factory test report is available on request per batch.
Each stage is designed to stop a defect from reaching the next, so a resin problem never becomes an extrusion problem, and an extrusion problem never becomes a container problem.
“It meets PN25” only means something if it’s tested. We treat pressure, temperature and dimensions as specs to be verified, not slogans to be printed. PPR and PE products run through pressure and temperature testing to confirm they hold their rated PN class under hot- and cold-water conditions, and dimensional checks confirm outer diameter and wall thickness across the 20–63 mm range match the target, not a thinner, cheaper version of it.
| Test | What it confirms | Why it matters to you |
|---|---|---|
| Pressure test | Holds its rated PN class (PN20 = 20 bar / PN25 = 25 bar at 20°C) | No burst behind the wall or under load |
| Temperature / hot-water | Performs under hot & cold water conditions | Safe for heating, hot water, radiator & solar use |
| Dimensional test | OD & wall thickness match spec (20–63 mm) | No understated wall, no fit problems on-site |
| Report | Documented result per batch | Verify before shipment / for site sign-off |
Where you need proof, a factory test report is available on request, verify the batch before shipment or during site inspection instead of finding out on-site. AQL sampling level and exact tolerance figures are available on request.
Dimensional control only means something if there’s a hard target behind it. This is the wall-thickness matrix our PPR range is extruded and checked to, the same numbers you’ll find on our datasheet, quoted here so you know exactly what “matches spec” is being measured against for each size and PN class.
| OD (mm) | PPR PN20 | PPR PN25 | PPR-AL-PPR PN20 | PPR-AL-PPR PN25 | Fiberglass PN20 | Fiberglass PN25 |
|---|---|---|---|---|---|---|
| 20 | 20 × 2.8 | 20 × 3.4 | 20 × 3.1 | 20 × 3.4 | 20 × 2.8 | 20 × 3.4 |
| 25 | 25 × 3.5 | 25 × 4.2 | 25 × 3.3 | 25 × 4.2 | 25 × 3.5 | 25 × 4.2 |
| 32 | 32 × 4.4 | 32 × 5.4 | 32 × 4.1 | 32 × 5.4 | 32 × 4.4 | 32 × 5.4 |
| 40 | 40 × 5.5 | 40 × 6.7 | 40 × 5.0 | 40 × 6.7 | 40 × 5.5 | 40 × 6.7 |
| 50 | 50 × 6.9 | 50 × 8.4 | 50 × 5.5 | 50 × 8.4 | 50 × 6.9 | 50 × 8.4 |
| 63 | 63 × 8.6 | 63 × 10.5 | 63 × 7.0 | 63 × 10.5 | 63 × 8.6 | 63 × 10.5 |
All figures are OD × wall thickness in mm. PN20 = 20 bar and PN25 = 25 bar working pressure at 20°C. Article numbers: PPR plain PN20 = BK-001–006, PN25 = BK-007–012; PPR-AL-PPR PN20 = BK-01–06, PN25 = BK-07–12; Fiberglass PN20 = BK-13–18, PN25 = BK-19–24. Exact tolerance bands and AQL sampling level are available on request.
The complaint that quietly kills reorders isn’t a burst pipe, it’s a job where batch two doesn’t match batch one. A shade of green that drifted, an OD that crept out of tolerance, a fitting that no longer seats cleanly.
Bekaatherm controls this at the source: consistent masterbatch dosing keeps our green, white and coffee lines matching from run to run, and 10,000 in-house molds keep fitting geometry repeatable instead of drifting between suppliers. In-line checks flag any deviation before it becomes a full batch, so what you reorder next quarter looks and fits like what you approved last quarter. Because pipe, fittings and valves are all made in-house from the same material family, a green socket seats cleanly on a green pipe and matches its color, instead of the mismatched patchwork you get when parts are sourced from three different factories.
| Consistent masterbatch dosing | Green / white / coffee hold color across batches |
| 10,000 in-house molds | Repeatable fitting geometry, clean seating |
| In-line process control | Deviation caught before a full batch is made |
| Single manufacturer, matched system | Pipe + fittings + valves same material, same color |

Whether you brand in green, white or coffee, the same masterbatch discipline and mold set hold color and geometry constant, so a private-label order in your house color looks identical from the first container to the hundredth.



A QC claim is easier to trust when you can see the plant behind it. Across our 120,000 m² facility, 1,000+ staff run extrusion, molding, brass insertion and export loading under one roof, the same integrated production that keeps material, color and geometry consistent.












Internal QC is only as good as its outside proof. Bekaatherm carries SKZ (Germany), described in our field as one of the strictest certifications in the piping industry, precisely because SKZ doesn’t only certify the finished product, it monitors how the company produces it. That’s third-party confirmation the QC system on this page actually runs, not just exists on paper. Alongside SKZ, our range is backed by ISO TYPE-5, CE and WRAS, covering quality management, European conformity and drinking-water safety.

OEM & Private LabelFor the Importer: We run 100% high-standard virgin resin with consistent masterbatch dosing, so green, white and coffee hold color run to run, and 10,000 in-house molds keep fitting geometry repeatable. In-line checks catch any drift before it becomes a full batch, so container two matches container one.
For the Contractor: Yes. PPR and PE products undergo pressure, temperature and dimensional testing, and a factory test report is available on request. You can verify the PN rating, wall thickness and dimensions before shipment or hand the report to site inspection for sign-off, so the batch is proven before it’s installed.
For the Project Buyer: Wall thickness is matched to the PN20 / PN25 rating across the 20–63 mm range, for example a 25 mm PPR pipe runs 3.5 mm wall at PN20 and 4.2 mm at PN25, and is checked dimensionally in production against the target, not left to chance or thinned to cut cost. Exact tolerance figures and our AQL sampling level are available on request for your technical file.
For the OEM Brand: Because a third party audits it. SKZ (Germany), among the strictest in the piping industry, certifies our products and monitors our production process, alongside ISO, CE and WRAS. Certificate numbers are available on request, giving you documented, verifiable proof rather than a marketing promise.
For the Contractor: Our PPR range covers PN20 (20 bar at 20°C) and PN25 (25 bar at 20°C) in plain, aluminium-composite and fiberglass-composite structures, sized 20–63 mm. HDPE / PP compression fittings are rated PN10 for outdoor water and irrigation. Each class is confirmed by pressure and temperature testing before shipment.
For the Distributor: Yes, pipe, fittings and valves are produced in-house from the same 100% high-standard material family, with brass inserts on threaded and valve items. One manufacturer, one QC system and 10,000 molds mean a green fitting seats cleanly on a green pipe and matches its color, container after container, instead of a mismatched patchwork from three suppliers.
