Product Description
Medium frequency hot process elbow machine engineered for forming large-diameter pipe elbows from 5" to 16". The system combines hydraulic propulsion, intermediate frequency heating, and a three-stage hydraulic pump station for continuous, stable production of carbon steel, alloy steel, and longitudinal welded pipe elbows.
Performance Specifications
- Maximum push elbow diameter: 426 mm; minimum elbow diameter: 141 mm.
- Wall thickness range: 6–12 mm.
- Carbon steel seamless pipe materials: 20G, A106B, A106C.
- Alloy steel seamless pipe materials: 355P12, 15CrMo, 12Cr1MoV, P22, P91, WB36, and more.
- Longitudinal welded pipe materials: Q235B, Q345B, X42, X52, X60, X65, X70, X80.
- Operating environment: ambient temperature 5–38 °C, relative humidity ≤82%, three-phase four-wire 380V input (-12% to +15%), frequency 50Hz ±2%.
- Designed for continuous 24-hour operation in a non-corrosive workshop with sufficient space.
Oil Cylinder Construction
- Manufactured in compliance with JB/T10205-2000 and JB/T15622-2005 standards.
- Cylinder body made of 45# steel with inner surface finish Ra0.4; piston rod made of 45# seamless pipe, chrome-plated and polished to Ra0.3 with no straight or spiral lines.
- All other cylinder parts are 45# forgings to ensure mechanical performance.
- Main cylinder piston guide sleeve uses a copper sleeve; all seals follow the standard priority series; the main oil seal is imported Austrian AGCO.
- Finish, hardness, matching dimensions, forging quality, and seal quality are inspected before assembly, followed by a pressure test after assembly.
Main Cylinder Parameters
- Thrust: 180 tons (two cylinders)
- Structure: Piston structure with front and rear flanges
- Test pressure: 31.5 MPa
- Working pressure: 0–25 MPa
- Inner diameter: 220 mm
- Outer diameter: 273 mm
- Piston rod diameter: 160 mm
- Material: 45# steel
- Effective stroke: 4 m
Main Engine Structure
- Composed of underframe, cylinder support plate, movable push plate, front baffle, and tug boat.
- Body welded and assembled from Q235A medium plate, channel steel, and round steel.
- Push plate and underframe use an upper pulley and guide rail structure for stable operation.
- Front baffle and cylinder are equipped with hydraulic mandrel adjustment cylinders.

Hydraulic Pump Station
- Maximum working pressure of the hydraulic system: 25 MPa; test pressure: 31.5 MPa.
- Fuel tank inner and outer surfaces are anti-rust treated, with an internal filter screen and liquid level and oil temperature indicators.
- The entire hydraulic system is cleaned before oiling and trial operation.
- Three-stage pump station design for coordinated high-pressure and fast-motion control.
- Integrated block connection for stable, leak-free operation.
Pump Station Stages
- Stage 1: 63 L/min high-pressure main pump with 18.5 kW motor for pushing and attack control.
- Stage 2: 80 L/min gear pump with common four-stage motor for fast forward and fast rewind; maximum advance speed 1200 mm/min, maximum rewind speed 1800 mm/min, working speed 0–500 mm/min infinitely variable.
- Stage 3: 10 L/min gear pump for auxiliary hydraulic actions such as gate operation on pipe benders.
Design Form
- Hydraulic propulsion with stepless speed regulation.
- Intermediate frequency heating.
- Chain feed system.
- Hydraulic insert plate, hydraulic tug wheel, and manual gate.
- Centralized power supply and motor operation control on a single operating cabinet, including power shutdown, break-off, and cooling water pump start/stop control.
