DOUBLE-WALL WEAR-RESISTANT PIPES
MAXIMUM RESISTANCE TO WEAR AND OUTSTANDING PRICE/PERFORMANCE RATIO

Double-layer pipes with wear-resistant steel inner wall with hardness up to 67 HRC.
DALCOM produces a complete range with inner diameters of 100, 112, 117, and 125 mm and a wide range of thicknesses. The rings are welded with a special cooling process that maintains the alloy’s characteristics and hardness.
We supply the complete pipeline, including special pipes, and you can also choose the colour you prefer.
Our double-layer pipes are a benchmark for quality and durability

PIPES FOR PUMP BOOMS – DW403- DW275 – DW44 – DW46

Double-layer pipes consisting of a 2 mm thick outer wall and a 2.5 mm thick inner wall, and with hardness up to 67 HRC. Collars with inserts made of chrome steel with increased thickness. Compliance with all tolerance, pressure, and safety requirements

PIPES FOR PUMP BOOMS – DW403- DW275 – DW44 – DW46

Technical characteristics

  • Lasting up to 5 times more than normal ST52
  • Reduced downtime
  • Maximum collar life and increased protection of the pipe
  • Weight per linear metre equivalent to ST52
  • Compliance with all tolerance, pressure, and safety requirements

Double layer thickness 2.5 + 2 mm

Available diameters:
4” = 100 mm / 4.4” = 112 mm / 4.6” = 117 mm / 5” = 125 mm

PIPES FOR PUMP BOOMS – DW325

Double-layer pipes consisting of a 1.5 mm thick outer wall and a 3.25 mm thick inner wall, and with hardness up to 67 HRC. Special collars with CCI chrome carbide steel inserts with a reinforced section at the points of greatest wear

PIPES FOR PUMP BOOMS – DW325

The DW325 pipe, while maintaining weight, size, and safety restrictions, have up to 30% more resistance than the 2.5 + 2 double-layer pipes

CARRIAGE AND TURRET PIPES – DW405 – DW500

Double-layer pipes consisting of a 3 mm thick outer wall and a 5 mm thick inner wall, and with hardness up to 67 HRC. Exclusive collars with an insert made of chrome carbide alloy (CCI) with increased thickness guarantee a longer life while complying with all tolerance, pressure, and safety requirements

CARRIAGE AND TURRET PIPES – DW405 – DW500

Technical characteristics

  • Ideal on the turret and on the pipes along the carriage
  • Internal pipe thickness 5 mm and hardness up to 67 HRC
  • Maximum collar life and increased protection of the pipe
  • Reduction in machine maintenance time
  • Weight per linear metre equivalent to ST52
  • Available diameters: 4” = 100 mm / 5” = 125 mm

Construction of pipes that are highly resistant to wear, suitable for turret and carriage pipes with collar core designed with a particular profile and made in a single casting of chrome carbide (CCI)

Available diameters: 4” = 100 mm / 5” = 125 mm

LONG LIFE ELBOWS – LL

Reinforced manganese alloy elbows and double-layer collars with inserts made of chrome steel with increased thickness solve the problem of premature wear. Ideal for the delivery boom in combination with straight or double-layer pipes made of HB400

LONG LIFE ELBOWS – LL

The manganese alloy is particularly resistant to impacts and the CCI inserts provide high resistance to wear

CHROME CARBIDE ELBOWS – CCI

We have succeeded in obtaining a special alloy with hardness up to 68 HRC and high wear resistance characteristics that allow a life of up to twice that of common double-layer elbows. The collars are made of CCI with an oversized “BIG MOUTH” section for maximum resistance at the ends

CHROME CARBIDE ELBOWS – CCI

Available with internal thickness of 7 mm for all boom positions or 10 mm for the turret or any area subject to heavy wear

IMPACT ELBOWS – CCI

Elbow suitable for all points of impact and concrete fall on the delivery boom. The best product on the market today

IMPACT ELBOWS – CCI

Elbow suitable for all points of impact and concrete fall on the delivery boom. The best product on the market today

DOUBLE-LAYER REDUCERS WITH CCI INSERTS

Double-layer reducers with chrome carbide (CCI) inserts and hardness up to 68 HRC
