Detailed Introduction

German standard cross belongs to pipeline cross-node butt welding pipe fittings, undertaking the diversion and confluence of four-way media. The products are produced according to the German industrial pipe fitting standards DIN2615 and DIN2605, and the outer diameter, center height, bevel form and wall thickness tolerance follow the German DIN system. Although the old DIN standards have been replaced by the European standard EN10253, there are still a large number of existing DIN pipelines, old installations and German-system complete equipment in Germany, Austria, Switzerland, as well as the Middle East and Africa that are using German standard crosses, and such projects usually cannot be directly replaced with ordinary European standard pipe fittings. In terms of specifications, it covers DN15–DN1200; small diameters adopt seamless hot extrusion forming, and large diameters adopt steel plate rolled and welded fabrication; materials include carbon steel St37.0, St52, alloy steel 13CrMo44, as well as German standard stainless steel 1.4301 and 1.4571. Pressure ratings are PN10–PN160, divided into reduced-pressure type and full-pressure type. Hydrostatic testing and UT/RT non-destructive testing can be carried out on demand, and EN10204-3.1B material certificates can be issued.

  • Produced according to the German industrial standards DIN2615 and DIN2605, the outer diameter, center height, bevel form and wall thickness tolerance follow the German DIN system, suitable for projects that need to match the engineering acceptance requirements of the German-speaking region.
  • Specifications cover DN15–DN1200; small diameters are formed by seamless hot extrusion, and large diameters are fabricated by steel plate rolled and welded, and the corresponding process can be confirmed according to the project's diameter and structural requirements.
  • Materials cover carbon steel St37.0, St52, alloy steel 13CrMo44, as well as German standard stainless steel 1.4301 and 1.4571, making it easy to match material selection according to the medium and working conditions.
  • Pressure ratings cover PN10–PN160, divided into reduced-pressure type and full-pressure type, and the specific rating and structural form can be confirmed according to the pipeline design pressure.
  • Hydrostatic testing, UT/RT non-destructive testing can be carried out, and EN10204-3.1B material certificates can be issued, facilitating engineering supervision acceptance in the German-speaking region and the preparation of cross-border customs clearance documents.
  • For the maintenance and replacement scenarios of existing DIN pipelines in Europe from the last century, we can cooperate in checking against the dimensions and drawings of old parts, reducing the risk of alignment deviation when replacing old pipelines.

FAQ

Can DIN standard crosses be used in projects within Germany and pass supervision acceptance?

The products are produced according to DIN2615 and DIN2605 German industrial standards. Dimensional precision, material, groove, and pressure-bearing parameters comply with German industrial specifications. We can cooperate to provide EN10204-3.1B material certificates and hydraulic test, UT/RT non-destructive testing reports, facilitating engineering supervision acceptance and cross-border customs clearance in German-speaking regions. Please contact us to confirm the specific project acceptance requirements.

Can DIN standard crosses and European standard crosses be directly interchanged?

The two have different outer diameter, tolerance, and wall thickness systems. German-standard crosses are produced according to the DIN system and cannot be freely interchanged with ordinary European-standard pipe fittings. Old German DIN projects usually require genuine DIN German-standard pipe fittings. It is recommended to provide the original pipeline drawings or old part dimensions before procurement, and we will assist in verifying compatibility.

Do you support small-batch trial orders or mixed-batch procurement?

We support small trial orders for test sales, and they can be mixed with the full range of German-standard pipe fittings in mixed batches. Regular in-stock standard specifications cover mainstream diameters from DN15–DN600, conventional pressure ratings of PN16/PN25/PN40, and materials such as St37 carbon steel. For specific minimum order quantities and mixed-batch solutions, please contact us for confirmation.

Can non-standard diameters or old part replacements be customized?

We can customize non-standard diameters from DN15–DN1200, non-conventional reducing ratios, thickened wall thicknesses, and extended straight pipe section special-shaped crosses according to German-standard drawings. We also support 1:1 replication of old European parts. Material options include St37/St52 carbon steel, 13CrMo44 alloy steel, and 1.4301/1.4571 stainless steel. The sample production cycle is 3–5 days. Please provide drawings or old part dimensions so that we can assist in confirmation.

What inspections are carried out before the products leave the factory?

Hydrostatic testing and UT/RT non-destructive testing can be carried out according to project requirements, and EN10204-3.1B material certificates can be issued. For large-diameter rolled and welded products, 100% RT/UT non-destructive testing can be performed. For specific inspection items and acceptance standards, please contact us for confirmation.
