Alloy steel Long Sweep Swivel Joints, Brand Name : Taizhi

Long sweep or long radius swivel joints are designed and manufactured in line with world famous brand products to handle a complete range of high pressure and abrasive oilfield fluids, and swivel joints can be interchangeable with those world famous brand products.
Long sweep Swivel joints are made of high quality forged alloy steel that meet ASTM or AISI standards, and the forged material are free from cracks, blow holes and other forging defects. After full heat-treatment, each forging are checked for surface cracks by performing hydro test. Swivel joints features uniform thickness of wall, long radius and streamlined bore, such can assure swivel joints to serve with super performance, and assure swivel joints can handle crude oil, natural gas, brine, steam, water, mud, cement slurry, acids or any mixture of above at a cold working pressure from 5000psi to 15000psi in high-pressure discharge lines, water lines, temporary flow lines, well testing lines, cementing and circulating lines, and other high-pressure applications at temperature and temperature of 20° to 250° F.
Long radius Swivel joints are designed with tri-race ball bearing to join subs of swivel joints for rotation, such can assure axial load capacities, and each swivel joints can rotate 360°. For ball bearing of swivel joints, ball races are embedded with snap ring made from hardened alloy steel SS-304/EN-47/AISI-6150 and the grooves of balls are properly greased with good quality grease. The groove surface are hardened and tempered up to BHN 350-450 with a depth of hardness from 0.8-1.00 mm.
