Pipe Bends, Branches, and Reducers – HS-Umformtechnik

At Sutein, we work with HS-Umformtechnik, a German company specialized in the production of pipe bends and accessories for pneumatic conveying in the food, chemical, and plastics industries — sharing our same commitment to quality and service.

Thanks to our wide stock of HS Umformtechnik pipe bends, we help companies avoid the need to carry out tube bending either in-house or externally, reducing manufacturing lead times, process costs and dimensional inaccuracies. We supply ready-to-install solutions with fast delivery and precise geometries.

We use certified tubing according to EN 10357 / DIN 11850, ensuring maximum precision, cleanliness, and safety in all processes. Each piece is welded and polished internally, guaranteeing a smooth flow, no product retention, and long system life.

We keep a large stock of the most demanded pipe bends and accessories references, continuously updated to provide fast delivery and reliable service to our customers.

Tubos curvados y curvas en acero inoxidable AISI 304 y AISI 316 para transporte neumático

Stainless-steel pipe bends in AISI 304 and AISI 316

Our core speciality are thin-wall tube elbows with large bending radii, designed specifically for pneumatic conveying systems. They are mandrel-bent on CNC equipment, a process that prevents wrinkles, deformation and loss of cross-section, ensuring optimum product flow and a long system life.

Features

  • Safe handling, with no sharp edges
  • Butt-welded or cut to DIN 11850 / DIN 17457
  • Completely smooth inner surface
  • Minimal ovality and excellent surface finish
  • Straight ends on both sides
Curvas HVA-Niro resistentes al desgaste para transporte neumático de sólidos abrasivos

HVA-Niro pipe bends (high wear resistance)

Made from highly wear-resistant stainless steel, these pipe bends offer a service life 10 to 20 times higher than standard elbows. Ideal for conveying granulates reinforced with glass fibre or other abrasive products.

Features

  • Suitable for highly abrasive products
  • Simple installation, no special couplings required
  • Approved for food use
Curvas de cristal borosilicato 3.3 para transporte neumático y control visual del producto

Borosilicate glass 3.3 pipe bends

Designed for highly abrasive media or high flow rates, they provide a service life up to 10 times greater than metal pipe bends. They include a copper earthing wire to dissipate static electricity.

Features

  • 3.3 borosilicate glass
  • Straight ends on both sides
  • External earthing via copper wire
Curvas de doble pared DWR para transporte neumático de sólidos abrasivos a alta velocidad

Double-wall pipe bends DWR

An ideal solution for pneumatic conveying of highly abrasive products at high velocity. The double-chamber design with a stainless-steel inner elbow acts as a sacrificial layer; when the inner wall wears, the flow changes to “product over product”, eliminating axial wear.

Available versions

I. Product over product

  • Classic double-pipe system)
  • Not suitable for food use or frequent colour changes

II. Concrete-lined option

  • Inner lining with high-strength concrete (>100 N/mm²)
  • Properties similar to ceramic
  • Grey colour finish
  • Not suitable for food use
  • Also available with 3.3 borosilicate glass lining
