Make sure you mount new wheels properly using the correct mounting flanges and that the outer mounting flange nut is not over-tightened.

To install the bolt body, it is inserted in the hole through the two flanges with the sleeve in the elearanee position. Hydraulie pressure pushes the sleeve into the final (interferenee) fitted position, and the puller draws the bolt baek into the sleeve. The nut is fitted at one end and the bolt is hydraulieally tensioned with the other nut. The entire proeess takes about 15 min per bolt. 

Material requirements for pipe, flanges, fittings, bolts, nuts, and gaskets. 

Nobody knows why this had been done. Probably one nut was tighter than the other, and in attempting to tighten this nut, the whole stud was screwed through the second nut. Whatever the reason, it produced a dangerous situation because the pressure on different parts of the flange was not the same. 

Carbon Steel Bolting. Except where limited by other provisions of this Code, carbon steel bolting may be used with nonmetallic gaskets in flanged joints rated ASME B16.5 Class 300 and lower for bolt metal temperatures at -29°C to 204°C (-20°F to 400°F), inclusive. If these bolts are galvanized, heavy hexagon nuts, threaded to suit, shall be used. 

For all flange joints, the bolts or stud bolts used shall extend either completely through the nuts or one thread short of the full nut. 

Flanged openings shall be provided with metal closures at least 5 mm (0.19 in.) thick, with elastomer gaskets and at least four full diameter bolts. For studded openings, all nuts needed for the intended service shall be used to secure closures. 

The myriad types of l.c. fittings produced by a great number of vendors have led to confusion among chromatographers about the proper choice for each application. Fortunately, fittings that are more universal in their applications are now available, and one of the most useful of these has a knurled flange on the nut, and a replaceable, polymeric ferrule. These fittings may be sealed by hand and re-used many times without failure.

When flanges or the cover of vessels should be opened it is recommended to remove the nut of bolts only turn by turn and to prove that there is no pressurised content behind the flange or the cover. 

Some cadmium-plated bolts and nuts were purchased and installed as a test in the plant. More bolts were purchased and eventually some of the cadmium-plated bolts were installed on the outlet piping flanges of a cracking furnace. The high temperature outlet flanges on the furnace started to weep a bit. An experienced, intelligent pipefitter attempted to snug up a few bolts and the nuts crumbled. (The cause of the failure was later determined to be due to corrosion phenomena called liquid metal embrittlement. )... 

The pressure vessels are hollow cylinders, of 100- to 10,000-liter capacity, having a flange onto which the cover is fastened by means of bolts and nuts. The bottom of die vessel is usually hemispherical for greater strength. Autoclaves are almost always made of iron, either cast steel or cast iron, the former being safer to use at high pressures. Sheet iron is also used, in wall thicknesses up to 40 mm., in either riveted or welded construction. The reluctance in many dye plants to use welded autoclaves is entirely unjustified and has arisen simply because in the early days of the industry welding processes had not been perfected. 

All Flanges Include prorata of gaskets, bolts nuts. Trims Include 3/4 in. coup, and 3/4 In. plug valve.
