　Slip-On flanges are commonly lower in price than weld-neck flanges, and to this effect are a popular choice for our customers. However, customers should bear in mind that this initial cost saving may be diminished by the additional cost of the two fillet welds required for proper installation. Moreover, weld-neck flanges have a higher life expentancy than slip-on flanges under duress. 　　The slip-on flange is positioned so the inserted end of the pipe or fitting is set short of the flange face by the thickness of the pipe wall plus 1/8 of an inch, which thus allows for a fillet weld inside the SO flange equal without doing any damage to the flange face. The back or outside of the slip-on flange is also welded with a fillet weld. 　　We have a staff of 298,including 80 professional technicians,and our company covers an area of 160,000 square meters.In order to provide high quality,economically priced industrial tubes,carbon steel pipe fitting,and industrial pipe fitting,we have purchased testing equipment which is used for chemical analysis,water pressure testing,X-ray inspection,ultrasonic testing,eddy current inspection,tension testing,chemicaltesting,etc.We are also ISO9001:2000 approved
