SSAW pipe full name is Spiral Submerged arc welding pipe. The pipe is formed by spiral submerged arc welding technology which is called SSAW pipe. Generally speaking, when it comes to the same standard and steel grade, the price of SSAW pipe is cheaper or lower than ERW pipe and LSAW pipe. The strength is higher than the straight seam welded pipe.

JOCE LSAW Welded Steel Pipes (Press Bending)

Longitudinal submerged arc welded is produced by using a single medium and thick plate as the raw material, pressing (rolling) the steel plate in a mold or forming machine into a tube blank, using double-sided submerged arc welding, and expanding the diameter.

Galvanized Welded Steel Pipe

Galvanized welded pipe is hot dip galvanized on the basis of welded steel pipe (that is, the zinc is dissolved in the zinc pot, and then the steel pipe is immersed in liquid zinc for a period of time, and then cooled and dried). The inner and outer walls of the steel pipe are simultaneously attached with a zinc layer. Galvanized pipes are generally used for conveying low pressure fluids (i.e. water, liquid gas).

ERW Straight Seam Welded Pipe

High-frequency welded pipes are generally straight-slit, but straight-slit welded steel pipes are not necessarily high-frequency welded. The high-frequency straight-slit electric resistance welded steel pipe is formed by the skin effect and the proximity effect of the high-frequency current after the hot-rolled coil plate is formed by the molding machine, and the edge of the tube blank is heated and melted, and pressure welding is performed under the action of the pressing roller to realize the production. The high-frequency resistance welded steel pipe is different from the ordinary welded pipe welding process. The weld is made of the base material of the steel strip body, and the mechanical strength is better than that of the general welded pipe. The surface is smooth, high precision, low cost, and has low weld seam height, which is beneficial to the coating of 3PE anti-corrosion coating

EN 10025-2 Seamless Steel Pipes

En 10025 Pipes manufacturer produce these carbon steel pipes with carbon, silicon, manganese, phosphorus, and sulfur content. The carbon content is 0.2% of the total weight. The EN 10025 Steel Pipes is made in seamless and welded conditions. The difference between the two is that the welded pipes have larger diameters and high absolute roughness where the En 10025 Seamless Pipes have low absolute roughness and smaller diameters.

ASTM A671 Welded Steel Pipe

A671 Pipe specification covers electric-fusion-welded steel pipe with filler metal added, fabricated from pressure vessel quality plate of several analyses and strength levels and suitable for high-pressure service at atmospheric and lower temperatures. Heat treatment may or may not be required to attain the desired properties or to comply with applicable code requirements. Supplementary requirements are provided for use when additional testing or examination is desired.

ASTM A53 Seamless and Welded Steel Pipe

ASTM A53 and ASME SA53 is intended for mechanical and pressure applications and is also acceptable for ordinary uses in steam, water, gas and air lines. It is suitable for welding and for forming operations involving coiling, bending, and flanging, subject to certain qualifications.

Seamless Steel Pipe Thick Walled Tube

The pipe diameter and wall thickness ratio of less than 20 is called thick-walled steel pipe, which is mainly used in petroleum geology drilling pipe, petrochemical used cracking tubes, boiler tubes, pipes and automotive bearings, tractors, aviation structures with high precision tubes.

Seamless Steel Pipe Structural Tube

Structural steel pipes are hollow cylindrical tubes that are strong enough to transport chemicals and bear heavy weight loads, which is why they have numerous applications across a range of industries.

Seamless Steel Pipe Mechanical Tube

Mechanical pipe, with high strength, high pressure resistance, easy installation, low cost, long service life and many other advantages, widely used in oil, natural gas, gas, water, medicine, health, products and other long-distance pipeline and petrochemical enterprise process pipe network, urban central heating pipe network, gas pipe network and other projects. In the use of construction machinery, there are often pipeline oil leakage, oil leakage problems, most of these problems are caused by unreasonable pipeline layout. Hydraulic piping system includes hydraulic oil tank, hose assembly, steel pipe assembly and connecting joints, etc. It is a hydraulic power transmission system of construction machinery, which can be described as the blood of the whole machine. However, in the design of construction machinery hydraulic system, pipeline as an accessory is often ignored. In actual use, due to the unreasonable layout of the pipeline, the pipeline is easy to be damaged, once damaged oil leakage, light pollution of the environment, affect the normal play of the system function

Seamless Steel Pipe Fin Tube

Finned tubes are the main components of heat exchangers. They are a series of tubes where fins have been added on the outside to increase the contact area with the outside fluid, to exchange heat and between the fluid inside the tube and the fluid outside the tube.

Seamless Steel Pipe Boiler Tube

Boiler tubes is a one of seamless pipe. Manufacturing methods is the same as seamless tube, but it has the stringent requirements for manufacture of steel pipes. According to the temperature level,boiler tube is divided into general boiler tubes and high pressure boiler tube.

ASTM A192 Seamless Steel Pipe

SA192 / ASTM A192 Is a high pressure seamless carbon steel / manganese boiler tube used in super heaters, water wall panels, heat exchangers, condensers, marine application, refineries, paper pulping, petrochemical applications, pressure vessels, and general engineering applications.

ASTM A106 Seamless Steel Pipe

ASTM A106 and ASME SA106 seamless pressure pipe is commonly used in the construction of oil and gas refineries, power plants, petrochemical plants, boilers, and ships where the piping must transport fluids and gases that exhibit higher temperatures and pressure levels.

ASTM 4140&4130 Seamless Steel Pipe

ASTM 4140 Steel is a Alloy Structural Steel belong to ASTM A29/A29M Steel Grade standard. AISI 4140 used in Oil and Gas industry and Large Machinery Strutural.
