TUBE SLOTTING MACHINE

Our customer is a major manufacturer of OCTG seamless and welded pipes:

his need was to produce a new range of seamless pipes aimed to shale oil

extraction and become a top player within that industry.

His difficulty was to find out a supplier of a reliable and repeatable technology

able to industrialize the production of slotting machines, that have been

manufactured at handicraft level so far. For this reason, he turned to LAZZARI,

his technological partner for many other pipe finishing machines.

The pipes to be machined have a range from 2 7/8” to 7”, thickness from

2.5mm to 11mm and lengths from 6m to 13,7m.

The slotting machine works in a dedicated line, being the constraint to

keep the slotting on the complete pipe surface within a 60 min cycle.

www.lazzarigroup.com lazzari@lazzarigroup.com

The technical innovation introduced by LAZZARI consists of:

maximum flexibility, as the machine is made of repeatable modules

allowing to design and build larger or smaller machines depending on

the needs;

high productivity with mandrels supporting one to four blades

equipped with quick change system;

machine handled by the operator based on multi-pattern solution i.e.

he can easily change the cutting patterns

www.lazzarigroup.com lazzari@lazzarigroup.com

As it happens in new projects, we experienced to overcome some

difficulties: for example to find out data about the cuts geometry, their

position all around the pipe (cut pattern) and the optimum type of cutting

tools as well as to solve the problem of their needs to be changed.

Moreover, a challenge has been to select the proper lube-cooler to reduce

the blade wear and machine vibrations: we spent a lot of time and trials to

get the best solution.

www.lazzarigroup.com lazzari@lazzarigroup.com

The project has been really large, by the involvement of ten peoples by

LAZZARI and the customer throughout 18 months: we have built a prototype

designed to become a series.

During that time we carried out the machine basic design, the design of

prototype module, the prototype validation, the machine production and the

internal tests before the installation at customer facility.

The uniqueness of the project comes from the first machine designed and

manufactured to get high pipe slotting production for a large variety of pipes.

ADVANCED SHOULDER POINT DETECTION SYSTEM FOR COUPLING MAKE UP MACHINES

ADVANCED SHOULDER

POINT DETECTION SYSTEM

FOR COUPLING MAKE-UP

MACHINES
Lazzari, in collaboration with an important Spanish tube producer for the Oil & Gas sector,

developed the function to automatically detect the shoulder torque and position of a coupling

make-up premium connection.

www.lazzarigroup.com lazzari@lazzarigroup.com

Our customer’s need was to help the production

operators and managers to verify the compliance of the

make-up according with the connection quality

requirements.

Our experience in the premium connection processes and

our availability to study and manufacture a completely

customized solution oriented the customer to ask

LAZZARI the proper solution to match their needs.

Our work started collecting and analyzing the customer

premium connection production data; then we designed a

solution able to reach the goal within the current

hardware and software state of art and we completed the

project in a new report station’s application with new

features.

www.lazzarigroup.com lazzari@lazzarigroup.com

In few months we have been able to start the

installation and test the new application: the

first goal was to avoid disturbing the

production and let the machine work also

with the original report system

simultaneously.

As we got a very positive result from the

tests, one month later we released the new

report station’s application for shoulder

point detection.

Our new algorithm analyzes the torque trend

data and detects the shoulder point (cyan

line red circle) in terms of torque and

position values; anyway the operator has the

possibility to detect it manually and confirm

it. The advantages of this new feature are:

1. make the operator not fully

responsible of the recognition of the

shoulder

2. allow a quick make-up post process

evaluation and analysis of the data

stored in a dedicated database

3. help the production manager to

confirm the goodness of a connection

4. certify the goodness of the

connection, completing the information

with a make-up printed report.

If you need a new coupling make up machine or just want to improve the quality process of your

existing one, this solution suits your needs.

A full customizable application and report generation fulfils all your possible requirements.
