φ114 High Frequency Welding Tube Mill Plc Automatic Control System

1 General Introduction

Ф114Q high-frequency welded pipe production line is designed to produce welded pipes of 20～114mm in diameter and 0.8～4mm in wall thickness as well as square and rectangular pipes and formed sections of the corresponding size. The products conform to BS/ASTM Standard. Adopting the advantages of the equipment of the same kind at home and abroad, each element of the production line is designed with new ideas. The application of Germany pass technology, PLC automatic control system and British Eurotherm digital speed regulating unit guarantee that the production line works reliably and operates and maintains easily. Being the best inside the state, the production line can also rival the advanced ones in the world.

• Quality and Service Warranty

Pre-sales service:

·We can provide pictures of the finished equipment before shipment to ensure the authenticity of our products.

·If the government does not allow the seller to leave China and go to the customer's country for equipment debugging, we will provide online remote guidance to the buyer’s engineer, and do seller’s best to provide a clear and complete layout to help the buyer with equipment installation and commissioning.

·If the Chinese government can allow the seller to leave China and go to the customer's country for equipment debugging, we will send engineers there as described below:

Equipment arriving at the buyer, the technical services personnel at the scene debugging, maintenance, equipment commissioning, commissioning, operation and maintenance instruction, responsible for technical training for equipment operation and maintenance personnel of the buyer.

The debugging time is one month,within one month The buyer need pay for the engineer salary EUR 150.00 one day one person,the supply the atrtickets for round trip,also need supply the local cost,like food, rooms and transform.If due to the buyer reason,delay the debugging time,the buyer need pay for the engineer EUR 150.00 one person one day.

Number of equipment commissioning engineers:At least three.

After-sales service:

Used in users abide by the rules, under normal operating equipment, since 12 months from the date of the arrival of the equipment, such as positively impact on the quality to use, parts damage lead to equipment can't normal work, factory will give the repair or replacement free of charge.The debugging time is one month,within one month The buyer need pay for the engineer salary EUR 150.00 one day one person,the supply the atrtickets for round trip,also need supply the local cost,like food, rooms and transform.If due to the buyer reason,delay the debugging time,the buyer need pay for the engineer EUR 150.00 one person one day.
