ERW Steel Pipe

ERW Steel Pipe is also called Electrical Resistance Welding Steel Pipe (HFW STEEL
PIPE). ERW steel pipe is one of our most professional products. And it is not as the
same as an ordinary pipe welding process, the welding basic metal is melted by its
own steel body, so it has better mechanical strength than the normal welded pipe.

• Features: ERW represents resistance welding, resistance welding with high
efficiency, low cost, saving materials, ease of automation and other characteristics.
This welding technology is usually used for small sizes pipes from 34mm-610mmm.
• Products details: the OD is 34~610mm, thickness:1mm-14mm, the
length :5.8m-25m.
• Standard: API 5L PSL1,PLS2,ASTM standard, EN Standard, GOST Standard, ect.
• Inspection: Raw Material Test Tensile Test, Yeild Strength, Elogation, Impact Test,
Chemical Analysis, Hardness Test, Charpy Impact Test, Metallographic
Examination, Final Product Test Hydraulic Test, On-line and off-line Ultrasonic
Test,Tensile Test ,Yeild Strength, Elogation, Hardness Test, Charpy Impact,
Flattening Test Chemical Analysis,Metallographic Examination.
• Application for Electrical Resistance Welded pipe: it is widely used in aviation,
aerospace, energy, electronics, automobiles, light industry and other industrial
sectors, it is an important process of welding technology.

Our

products

has

been

exported

to

many

other

countries

such

as:

America,Russia,Canada, Pakistan,India, Africa and so on. And we keep good
relationship with many national oil company ,such as EGPC,PETROJET,PDVSA,
NNPC, CNPC, ect.

EN Standard ERW Steel Pipe
Our Allland could also supply EN standard ERW steel pipe, since EN standard ERW
steel pipes are popular in the European market, such as EN
10219,EN10217,EN10224, EN S235/S275/S355 ERW pipes.

EN10219 Cold formed welded structural hollow sections of non-alloy and fine grain
steels.

ASTM ERW Steel Pipe

ASTM ERW steel pipe is the most widely used pipes expect the API 5l standard in
the national market. There are many types of the ASTM ERW steel pipes standards,
such as ASTM A53, ASTM A500 ASTMA106,ect.

Application for ASTM ERW steel pipes:it is a general, all-purpose pipe used in
generator plants, refineries, compressor stations, natural gas transmission, and
steam conduction. It is acceptable for welding, flanging, and bending.
We manufacture our ERW/HFW steel pipe at several U.S.-based facilities that
produce high-quality tubular products with low-residuals in a wide range of
strength levels with superior toughness.

API 5L PSL1 ERW Steel Pipe

• Introduction: API 5L PSL1 ERW steel pipe is one of our professional
products. The whole spelling of ERW is Electrical Resistance Welding. ERW
represents resistance welding, resistance welding with high efficiency, low cost,
saving materials, ease of automation and other characteristics. This welding
technology is usually used for smaller sizes pipes compared with LSAW steel pipes.

• Inspection: Raw Material Test Tensile Test ,Yeild Strength, Elogation, Impact Test,
Chemical Analysis,Hardness Test, Charpy Impact Test, Metallographic Examination.

• Final Product Test: Hydraulic Test, On-line and off-line Ultrasonic Test,Tensile
Test, Yeild Strength, Elogation, Hardness Test,Charpy Impact, Flattening Test,
Chemical Analysis, Metallographic Examination.

• Application for Electrical Resistance Welded pipe: it is widely used in aviation,
aerospace, energy, electronics, automobiles, light industry and other industrial
sectors, it is an important process of welding technology.

• Sales experiences: Our products has been exported to many other countries such
as America, Russia, Canada, Pakistan,India, Africa and so on. And we keep good
relationship with many national oil company ,such as EGPC, PETROJET, PDVSA,
NNPC, CNPC, ect.

API 5L PSL2 ERW Steel Pipe

API 5L PSL2 ERW steel pipe is one kind of the ERW steel pipes. API PSL2 ERW steel
pipes increases the chemical composition, notch toughness, strength and
supplemental NDE (nondestructive testing) mandate, behind the material number

should take note for delivery condition such as N, M, Q, R, etc. You can check the
chemical composition for PSL2 pipe as following

Table 5 . Chemical composition for PSL 2 pipe with t 25,0 mm (0.984 in)

(1) Based upon product analysis. For seamless pipe with t 20,0 mm (0.787 in), the
carbon equivalent limits shall be as agreed. The CEIIW limits apply if the carbon
mass fraction is greater than 0,12 % and the CEPcm limits apply if the carbon mass
fraction is less than or equal to 0,12 %.

(2) For each reduction of 0,01 % below the specified maximum for carbon, an
increase of 0,05 % above the specified maximum for manganese is permissible, up
to a maximum of 1,65 % for grades W L245 or B, but u L360 or X52; up to a
maximum of 1,75 % for grades L360 or X52, but L485 or X70; up to a maximum of
2,00 % for grades W L485 or X70, but u L555 or X80; and up to a maximum of
2,20 % for grades L555 or X80.

(3) Unless otherwise agreed, the sum of the niobium and vanadium concentrations
shall be u 0,06 %.

(4) The sum of the niobium, vanadium and titanium concentrations shall be u
0,15 %.

(5) Unless otherwise agreed, 0,50 % maximum for copper, 0,30 % maximum for
nickel, 0,30 % maximum for chromium and 0,15 % maximum for molybdenum.

(6) Unless otherwise agreed.

(7) Unless otherwise agreed, the sum of the niobium, vanadium and titanium
concentrations shall be u 0,15 %.

(8) Unless otherwise agreed, 0,50 % maximum for copper, 0,50 % maximum for
nickel, 0,50 % maximum for chromium and 0,50 % maximum for molybdenum.

(9) Unless otherwise agreed, 0,50 % maximum for copper, 1,00 % maximum for
nickel, 0,50 % maximum for chromium and 0,50 % maximum for molybdenum.

(10) 0,004 % maximum for boron.
