High-Viscosity Media Diversion Breakthrough: How DIN Cross Pipe Fitting's Streamlined Cavity Solves Slurry Blockage?

In the realm of industrial piping, few challenges are as persistent as high-viscosity media—where chocolate, adhesives, and mineral slurries (1,000-10,000 cP) cling to pipe walls, clogging junctions and halting production. YULONG Steel, a premier buttweld fittings manufacturer, introduces its DIN 2605/DIN 2617 cross pipe fittings, engineered with a streamlined cavity that reduces blockage incidents by 85% in viscous applications. This innovation merges German precision standards with fluid dynamics expertise, redefining how butt welding pipe fittings handle thick media across food processing, chemical, and mining sectors.

DIN 2605 and DIN 2617：The Standard Synergy of High-viscosity Diversion

DIN 2605 and DIN 2617 form the backbone of YULONG’s cross pipe fitting design for viscous media:

• DIN 2605specifies a minimum 1.5× wall thickness radius at branch junctions, eliminating sharp corners where slurries traditionally accumulate.
• DIN 2617mandates surface finish (Ra ≤ 0.8μm) for stainless steel variants, critical for non-stick performance in sticky applications like molasses processing.

Together, these standards create a cross pipe fitting that transforms turbulent flow into laminar motion, even for media with particle sizes up to 5mm—such as ceramic slurry in tile manufacturing.

DIN 2605/DIN 2617 Cross Pipe Fittings: The Revolutionary Fluid Mechanics of the Streamlined Inner Cavity

Contoured Geometry for Viscous Flow

YULONG’s butt welding pipe fittings feature a 3D-optimized cavity where:

• The junction angle is refined to 45° (vs. standard 90°), reducing flow separation by 60% as validated by computational fluid dynamics (CFD) in a cocoa butter plant.
• The inner radius transitions smoothly from 1.5D (DIN 2605 minimum) to 2D for high-viscosity models, creating a "scooping" effect that carries particles through the branch without eddies.

In a Polish confectionery’s caramel line (5,000 cP), this design cut cleaning frequency from daily to monthly, saving 120 production hours annually.

Material Synergy in Sticky Environments

• 316L Stainless Steel: Passivated surface (per DIN 2605) forms a chromium oxide layer that repels organic adhesives. A German plywood factory’s resin distribution system (8,000 cP) showed 90% less residue buildup compared to 304 stainless steel fittings.
• Duplex Steel (1.4462): For abrasive slurries (e.g., mining tailings with 3mm particles), its 400HB hardness resists erosion, maintaining cavity geometry for 5+ years—double the lifespan of carbon steel cross pipe fitting

Precision Welding for Uninterrupted Flow

As a certified buttweld fittings manufacturer, YULONG ensures:

• Weld seams ground to Ra ≤ 1.6μm, eliminating protrusions that catch viscous media. A Brazilian sugar mill’s molasses line (6,000 cP) passed 10,000-hour operation with zero blockages at the weld junction.
• Compliance with DIN 2617’s dimensional tolerances (branch offset ≤ 1mm), ensuring alignment with upstream/downstream pipes. This prevented "bottlenecks" in a US paint factory’s pigment slurry system (4,500 cP), where pressure drop remained stable at 0.2 bar/m.

Temperature Adaptability for Thermosensitive Media

• Insulated Variants: For hot asphalt (180°C, 3,000 cP), a 50mm mineral wool layer maintains viscosity, preventing solidification in the cavity. A Dubai road construction project’s cross pipe fitting maintained flow consistency through 45°C ambient temperatures.
• Cryogenic Compatibility: For chilled chocolate (12°C, 8,000 cP), 316L’s low thermal conductivity minimized frosting, avoiding blockages in a Belgian chocolate plant’s distribution network.

DIN 2605/DIN 2617 Cross Pipe Fittings: Industrial Validation

a. Food Processing Excellence

A multinational sauce manufacturer replaced standard tees with YULONG’s DIN 2605 cross fittings in their tomato paste line (7,000 cP):

• Blockage Reduction: From 3 incidents/week to 1/month, cutting downtime by 140 hours/year.
• Cleaning Efficiency: CIP (Clean-in-Place) cycle time reduced by 40% due to smooth surfaces, lowering water usage by 2,000 liters/day.

b. Mining Slurry Resilience

In Australia’s iron ore mines, the butt welding pipe fittings (DN300, DIN 2617) handled 10,000 cP slurry with 5mm particles:

• Abrasion Resistance: 0.02mm/year wear rate on cavity walls, outperforming competitors’ 0.1mm/year.
• Flow Stability: Pressure fluctuations decreased by 35%, extending pump lifespan by 2 years.

YULONG Buttweld Fittings Manufacturer’s Expertise in Viscous Flow Solutions

As a leading buttweld fittings manufacturer , YULONG integrates:

• Custom Cavity Engineering: Tailored 2D/3D radius designs for unique media (e.g., 2.5D radius for 15,000 cP drilling mud).
• DIN 2605/DIN 2617 Dual Compliance: Ensuring seamless integration in EU and global projects, such as a French cosmetics plant’s silicone slurry system that required both standards for regulatory approval.
• Rapid Prototyping: 48-hour turnaround for custom cross pipe fittingdesigns, critical for pilot-scale viscous media trials.

YULONG Steel’s DIN 2605/DIN 2617 cross pipe fitting transforms high-viscosity media handling from a operational headache to a streamlined process. By merging DIN standards’ precision with fluid dynamics innovation, these butt welding pipe fittings prove that even the stickiest, thickest substances can flow with efficiency—saving time, reducing waste, and ensuring uninterrupted production.

For industries where every blockage costs thousands, YULONG’s solution isn’t just a fitting—it’s a viscosity revolution.
