SJ101: GB/T F4A4-H08C F5A4-H10Mn2
AWS F7A4-EH14
1.Description:
LH-SJ101G is a special-purpose sintered flux developed especially for welding steel pipes that are used in the project of Transporting the Natural Gas from the West to the East. With the alkalinity of approx 1.8,it is shaped as grey,round grains and its grain size is 2.01.40 mm(1445 meshes). It can be used with either AC. or DC. The welding wire is connected to the posiitive electrode when used with DC. It has stable arc combustion,good slag detachability and a good appearance of weld. The weld metal has higher low-temperature impact toughness.
As a peculiar production technique is adopted,the flux possesses better moisture resistance and good strength of grains,which may satisfy the requirements for regular transportation,storage and recycling use in welding.The flux has less specific gravity when it is bulk packed.And it is consumed less during the welding.
2.Usage:
Matching with suitable welding wires (H08C,H08MnA,H10Mn2,H08MnMoA,H08Mn2MoA),it may weld many kinds of steel pipes,such as X52,X60,X65,X70,etc.It may also be used in multi-layer welding,double-side single-pass welding ,multiple-wire welding and narrow-gap submerged arc welding

5.Our Factory Introduction
LAIWU HULING WELDING is one of leading biggest manufacturer of Submerged ARC welding flux in China. The annual capacity of production is growing and up to12000 metric tons of agglomerated flux and 5000 metric tons of fused flux. The factory has established the R&D laboratory with the advanced inspection equipments in field of welding materials. Our company is located at Laiwu City near by the Jinan International Airport, and also is near the TAISHAN Mount of Shandong Province, China.
The Submerged-ARC welding flux has been approved and passed the inspection of quality with the province grade and the national grade in China. We strictly executed and produced the welding flux according to the industrial standards of GB/T 5293-1999, GB/T 12740-2003, GB/T17854-1999 and the China Classification Society-1996 completely. Our quality management has passed IS09001-2008 Quality System Certification.
The welding flux has been widely used in the Chemical engineering equipment, Heavy machinery, Pressure vessel, Boiler, Gas cylinder body, Spiral welded steel pipe, Steel structure building H-beam steel etc. We have been exported the welding flux to India, Indonesia, Egypt, Japan, Philippine and Jordan. The foreign customer usually purchased and preferred to the high quality Agglomerated flux ( LH-SJ101;LH-SJ301;LH-SJ501;LH-HF101G ) and Manganese oxide fused flux.
