Hydraulic Pipe Bending Machine Manufacturer,Supplier and Exporter in India

Product Code : EL-SWES-8750
Jlab Export is a leading Hydraulic Pipe Bending Machine Manufacturer,and suppliers in India

In a hydraulic pipe bender, a hand-operated hydraulic ram pushes a shaped former into the pipe and bends it cold. This machine is made in 9, 19 and 21 ton models. They take pipe from 21.3 mm up to 60, 88.5 or 108 mm, with wall thickness from 2.75 mm up to 4.5, 5 or 6 mm.

Choosing Between the Three Models

The 9 ton model has formers for 1/2, 3/4, 1, 1-1/4, 1-1/2 and 2 in pipe, a 250 mm stroke and a weight of about 53 kg. The 19 ton model adds 2-1/2 and 3 in formers, a 320 mm stroke and walls up to 5 mm, at about 117 kg. The 21 ton model adds a 4 in former, a 370 mm stroke and walls up to 6 mm, and weighs about 200 kg.

Pipe Bending Practicals for ITI Trainees

Trainees mark the start of each bend with a Tape Measure, bend steel pipe to a right angle and check the result with a Protractor. A common exercise is an offset: two equal bends that step a pipe run round an obstacle and back into line.

Pipe ends are cut square with a Hacksaw Frame while the pipe is held in a Pipe Vice. Welding students then join a bent length to a straight one, with the Pipe Welding Clamp holding the two in line.

Frequently Asked Questions

Which model should I choose?
Choose by the biggest pipe and the thickest wall you will bend. The 9 ton model takes pipe up to 60 mm with walls up to 4.5 mm. The 19 ton model reaches 88.5 mm and 5 mm walls, and the 21 ton model reaches 108 mm and 6 mm walls.

Why must the former match the pipe size?
The former supports the inside of the bend. If it is too large or too small for the pipe, the wall flattens, ripples or kinks. Use the former for the pipe’s nominal size, from 1/2 in up to the top size of your model.

Can it bend thin-wall tube or soft copper pipe?
It is made for pipe walls from 2.75 mm upward. Thin-wall tube and soft copper tend to kink in a heavy former. Bend them on a hand tube bender such as the Lever Type Tube Bender.

How do I allow for springback?
Steel pipe springs back slightly when the ram pressure is released. Bend a test piece first, measure the angle it settles at, and take each later bend a little further to make up the difference.

What does the maximum stroke tell me?
It is how far the ram can push the former. That is 250 mm on the 9 ton model, 320 mm on the 19 ton and 370 mm on the 21 ton. Larger pipe needs a longer ram travel to go round a full bend.
