The major equipment such as Plate Edge Milling Machine, Plate Edge Crimping Machine, Pipe Forming Press, Tack Welding Machine and Pipe Expander all adopt the technology and equipment of SMS MEER.
As a lsaw steel pipe factory, we will share the information and news about lsaw pipe. Like what is LSAW, the differences between LSAW and SSAW, or the differences between welded pipe and seamless pipe. And to show the lsaw pipe inspection method, lsaw pipe manufacturing process.
We have whole set of manufacturing and inspection equipment. And we have more than 15 years export experience. We have got API certificate, ISO certificate and CE certificate for many years. And through the news we hope our customers know our products and our factory in details. If you have any questions please tell me, and I will do my best to help you.
When we distinguish API 5L PSL 1 and PSL 2, we learn it from this 5 aspects: in Chemical Properties; in Mechanical Properties; in Manufacturing; in Inspections and defect repair; in certification & tractability.
How to select a good lsaw pipe manufacturer? When you need lsaw pipe, which companies to choose is a big question. If you want to choose a good lsaw manufacturer, first thing you must make sure is that the company is a factory, not a trading company.
LSAW is short for Longitudinally Submerged Arc Welding steel pipe. And these 5 aspects will help you recognize what is lsaw pipe. I will clarify from the aspect: raw material of lsaw pipe, weld seam, lsaw pipe size range, welding method, and length of lsaw pipe. From this five aspects, you will know the characters of lsaw pipe in these simple way.
Longitudinal submerged arc welded pipe can express as LSAW steel pipe. LSAW steel pipe, a type of longitudinally welded steel pipe produced by using the double sided submerged arc welding method.
In manufacturing processes, we can see SAW pipes (LSAW, SSAW) and ERW pipes are entirely different right from formation and welding etc.
We say the differences between steel pipe and tube from the 12 aspects such as diameter, wall thickness, producing process, and structurer and so on. You will find them below.
ERW steel pipe manufacturing process includes HFW. ERW have low, medium, high frequency welding processes, and HFW is specially for high-frequency electric resistance welding. The differences between ERW and HFW steel pipe, is EFW is a type of ERW process for ordinary and thin-wall thickness steel pipes.
We distinguish ASTM A53 and ASTM A106 steel pipe from 4 aspects below. Steel pipes according to different specification have different properties and application. And we will see the details differences between them.
This standard specifies DIN 30670 requirements for and methods of testing extruded and fused polyethylene coatings. It is applied at the works to DIN2448 or DIN2458 steel pipes that will be in contact with soil or water. It is intended to be used for quality assurance purposes.
