Descripetion of welded pipe equipment
This specification covers nominal (average) wall seamless and welded carbon and alloy steel pipe intended for use at low temperatures. Several grades of ferritic steel are included as listed in Table 1. Some product sizes may not be available under this specification because heavier wall thicknesses have an adverse effect on low-temperature impact properties.
1.2 Supplementary Requirement S1 of an optional nature is provided. This shall apply only when specified
by the purchaser.
1.3 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining
values from the two systems may result in nonconformance with the specification. The inch-pound units shall apply unless the “M” designation of this specification is specified in the order.

High Frequency Welded Pipe Line

Article by: http://www.greatwall-machinary.com/Φ76-High-Frequency-Welded-Pipe-Line-1146.html
Product Description:

The Φ76 High Frequency Welded Pipe Line is the main equipment in the high frequency welded pipe production line. It can be divided into different types according to the diameter and the wall thickness of the pipe. The mill can produce circular pipe, square and rectangular pipe and special pipe using low carbon steel & alloy steel.

The specific process flow is: 

Steel strips are first fed into the machine then are shaped into pipe blanks by rollers.

Then, under skin and proximity effects of high frequency electric current, induced electricity is concentrated onto the bonding surface of the pipe profile fringe.

The heated up pipe profile fringe is quickly moved to the welding temperature and finished welding under the squeeze roller's pressure.

After cooling, sizing and broad straightening,  the steel pipe of needed specification is achieved.

Our products such as roll forming unit, FFX forming unit, cage forming unit can produce X80 and J55 API petroleum casing pipes and petroleum and gas pipes, which conform to the standard of API-5L, API-5CT.

This unit can also produce special pipes for air cooling condenser used by electric power plants or steel mills.
