Gas metal arc welding (GMAW) is an effective method for joining light-gauge metals such as carbon steel and austenitic stainless steel. Thin-gauge materials24-ga. to 0.1875-in. carbon steel and 18-ga. to 0.1875-in. stainless steelare used in applications such as HVAC, automotive, mobile machinery guards and cabs, and small parts, as well as stainless steel food service and processing
Difference between ERW, SSAW, LSAW. Steel pipe for pipe technology, can be divided into (SML), mainly as the Oilfield internal transportation pipeline and small-diameter high-pressure natural gas pipeline, used for a small number of long-distance gas pipeline, the vast majority of long-distance pipeline with Direct seam high frequency (ERW), spiral submerged arc (SSAW), LSAW three (LSAW).

High frequency welding (HFW) steel pipe is that ERW pipe produced with a welding current frequency equal to or greater than 70 kHZ. Through high-frequency current welding resistance, the heat generated in the contact objects, so the objected surface are heated to the plastic state, then with or without forging to achieve a combination of steels.

Spiral Pipe Gauge We manufacture spiral pipe in 18, 20, 22, welding seam gauge spiral pipe steelsamp; 24 gauge galvanized metal. Stronger than other pipe Our pipe is up to 20% stronger than smooth pipe systems of the same gauge, due to the added spiral reinforcement. No painting required, will last years outdoors. Spiral Pipe Diameter Available in 3-inch to 36-inch diameter
Spiral Round Duct - Spiral Pipe of TexasThe 4-ply spiral lock-seams of spiral duct create a product that is stronger than traditional welded-seam round ducts of the same gauge. Spiral lock-seams have practically no leakage, and are the only mechanical seams exempted from sealing under energy standards such
The spiral steel pipe is a spiral seam steel pipe which is made of steel coiled coil as raw material, which is often heated and extruded, and welded by automatic double wire double-sided submerged arc welding process. The spiral steel pipe feeds the strip steel into the welded pipe unit.

Spiral Steel Pipe Submerged Arc Welding Process and Spiral Steel Pipe Process Spiral steel pipe submerged arc welding process Automatic submerged arc welding was invented in 1940, a new kind of welding method, it adopts slag protection as manual welding, but is not coated electrode, the slag is specially welding flux smelting.
Spiral Welded Pipe - Nucor SkylineThis allows for a lot more variation in diameter and thickness than ERW pipe. Spiralweld pipe is most commonly used for pipe diameters between 24 in. and 120 in. and for thicknesses of 1.0 in. or less. Manufacturing Process. The spiralweld manufacturing process is one of the most cost effective ways to produce steel pipe.

Spiralweld Pipe Naylor Pipe CompanyNaylor Spiral Buttweld Pipe features two welds along the spiral seam. This creates a pipe structure in which the weld is as strong or stronger than the parent metal. UNIFORM WALL. Because thickness tolerances of steel strip are governed by the standards established by the American Iron and Steel Institute, uniform wall thicknesses are assured.

The strength of the spiral welded pipe is generally higher than that of the ERW welded pipe.
What is a SSAW steel pipe?_news_Alloy steel pipe,Carbon SSAW steel pipe (spiral submerged arc welded steel pipe) is formed by spiral bending of hot-rolled strip steel, and spiral seam steel pipe (also called spiral welded pipe, spiral pipe spiral steel pipe) is formed by automatic welding of submerged arc for inner and outer joints. It can be widely used in the production of large diameter steel pipes for the following reasons:
The most popular process for large diameter pipe uses a longitudinal seam weld. Spiral welded pipe is an alternative process, spiral weld construction allows large diameter pipe to be produced from narrower plates or skelp. The defects that occur in spiral welded pipe are mainly those associated with the SAW weld, and are similar in nature to those for longitudinally welded SAW pipe.
Production process of spiral seam - nan-steelSpiral submerged arc welded steel pipe (SSAW Steel Pipe) refers to a metal pipe with spiral seam welded by submerged arc welding. Production Process. 1.Raw materials are strip steel coils, welding wires, and fluxes. Strict physical and chemical tests are required before investment.
