Steel pipe can be seen everywhere in our daily life. It is widely used in heating, water supplying, oil and gas transmission and other industrial fields. According to the pipe forming technology, steel pipes can be roughly divided into the following four categories: SMLS pipe, HFW pipe, LSAW pipe and SSAW pipe. According to the form of welding seam, they can be divided into SMLS pipe, straight seam steel pipe and spiral steel pipe. Different types of welding seam pipes have their own characteristics and have different advantages due to different applications. According to different welding seam, we make corresponding comparison between LSAW pipe and SSAW pipe.
LSAW pipe adopts double-sided submerged arc welding process. It is welded under static conditions, with high welding quality and short welding seam, and the probability of defects is small. Through full-length diameter expansion, the steel pipe has good pipe shape, accurate size and wide range of wall thickness and diameter. It is suitable for columns for bearing steel structures such as buildings, bridges, dams and offshore platforms, super long-span building structures and electric pole tower and mast structures which has requiring wind resistance and earthquake resistance.
SSAW pipe is a kind of steel pipe widely used in industry, construction and other industries. It is mainly used in tap water engineering, petrochemical industry, chemical industry, electric power industry, agricultural irrigation and urban construction.
