German standard pipe caps, also known as DIN heads and German standard pipe plugs, are core sealing accessories for the ends of German standard industrial pipelines. They are mainly used for closing German standard pipeline ports, reserving
Inquiry
German standard pipe caps are used to close pipeline ports, reserve spare nozzles, and provide temporary sealing during hydrostatic pressure testing, blocking the flow of media within the pipeline and preventing media leakage, impurity accumulation, and inner wall corrosion. The product is simultaneously compatible with the traditional German standard DIN 2617 and the current German standard DIN EN 10253, and is divided into Type A reduced-pressure type and Type B full-pressure type, with nominal diameters covering DN15-DN1200, wall thicknesses including SCH10 to SCH160 and the XXS thickened series, and pressure ratings from PN10 to PN100. The materials adopt German standard grades: carbon steel includes ST35.8, ST52, and C22.8; stainless steel includes 1.4301, 1.4404, and 1.4571; alloy steel includes 13CrMo44 and 16Mo3. Production processes include integral hot-pressed seamless forming, steel plate rolled and welded forming, and forged precision machining forming. We can assist in confirming the material, grade, and diameter configuration according to project operating conditions.

| Lead Time | The factory has established an independent dedicated production line for German standard pipe fittings and export constant-temperature warehousing, with sufficient in-stock reserves of German standard pipe caps in all specifications, efficiently responding to the delivery needs of engineering projects in Germany and Central Europe under the German standard system. Commonly used DIN2617, DIN EN10253 conventional specifications, Type A/B general grades, and mainstream material German standard pipe caps in the market are all in stock, order confirmation and payment |
| Packaging | German standard pipe caps adopt high-precision moisture-proof and shock-proof packaging dedicated for European export, adapting to long-distance cross-border transportation by sea, rail, and air to Central Europe, complying with German import environmental protection packaging and warehousing standards. Small DN15-DN100 specifications are fully wrapped in independent bubble film, with dust-proof and moisture-proof plastic protective caps added to the ports, isolating water vapor, dust, and oxidation dampness, individually packed into thickened export cartons, with the box body printed with English and German bilingual model, DN specification, SCH wall thickness, DIN standard, A/B grade, and batch information. Medium DN125-DN600 pipe caps are wrapped in double-layer waterproof and anti-corrosion woven fabric, with anti-collision protective pads added to the curved surfaces, preventing the precision curved structure from collision deformation and paint loss damage. Large DN700-DN1200 heavy-duty pipe caps use fumigated solid wood pallets for securing |

We adopt a flexible cross-border minimum order quantity model. For regular German standard in-stock specifications, a single piece can be shipped, and we also support mixed consolidation of multiple specifications and multiple grades, making it convenient to simultaneously advance sample submission for inspection, sporadic replacement parts for old pipelines, and batch complete-set projects. The factory has an independent production line for German standard pipe fittings and export constant-temperature warehousing. Common DIN 2617, DIN EN 10253 specifications, Type A/B general grades, and mainstream materials are all kept in stock. Packaging is tiered by specification: small sizes DN15-DN100 use full wrapping with bubble film, dust-proof and moisture-proof protective caps on the ends, and thickened export cartons, with the carton body printed with bilingual English and German model, DN specification, SCH wall thickness, DIN standard, AB grade, and batch information; medium sizes DN125-DN600 use double-layer waterproof and anti-corrosion woven fabric plus curved anti-collision protective padding; large sizes DN700-DN1200 use fumigated solid wood pallets for fixation, steel strip reinforcement, and multi-layer sealed wrapping, and the pallets comply with EU quarantine standards. All products are labeled by specification, grade, and material classification and undergo batch traceability, accompanied by bilingual certificates of conformity and material lists.
