How do you know what is the right pvc fitting for the right pipe size?

Corners pipe size can be determined by using pipe calipers.  Fitting sizes can be determined using sizing charts which can be found on Manville’s site (www.johnsmanville.com) under zeston fittings or on IDC’s site (www.idccorp.com) in Fiberglass Pipe Insulation or PVC Fittings.  http://www.idccorp.com/index~ID~,Mechanical.Insulation,PVC.Fittings~path~to~ds~dept

How to use a pvc fitting with an insert and without an insert and when to do that.

PVC fittings are never installed unless there is insulation in place on the fitting.  So do not use a PVC fitting so without some sort of insulation insert to place underneath it.  If you get PVC fittings that don’t have inserts, we recommend adding at least some unfaced insulation. http://www.idccorp.com/index~ID~,Mechanical.Insulation,PVC.Fittings~path~to~ds~dept

What is the correct way to apply a pvc fitting on a pipe?

Many of the 90 degree (AKA elbows) and 45 degree fittings are shaped so they are opened and shipped over the insulated fitting.  Some are elongated and must be pressed over the fittings to close.  Stainless Steel tacks are then inserted to secure the fittings on cold applications, all joints must be taped. PVC fittings must be installed over an insulated fitting.  A procured fiberglass insert is recommended but fittings of other types of material may be used. Tees, flanges, couplings and all Victaulic fitting are in two halves.  The two halves are trimmed to fit, need together with tacks and taped if necessary.

What are the various pipe covering options and the benefits of each

INSULATION JACKETING
INDOOR USE
Pipe insulation is sold with an all purpose jacket with a self sealing lap closure system.

INDOOR / OUTDOOR – PVC jacketing and fitting to enhance finished appearance indoors.
PVC should not be used where surface temperatures are above 140°F.
Outdoors PVC jacketing (at least .020″) and fittings can be used for enhanced appearance and weatherproofing. (PVC becomes brittle when ambient temperatures are below 20°F.

 

OUTDOOR – Aluminum jacket .016″ with smooth, corrugated or embossed finish can be used with preformed aluminum fittings up to 16″ IPS or PVC fittings. Jacketing thickness is also available in .006″, .010″, and .020″ depending on job requirements. The .016″ is most commonly used.

Stainless steel jacketing is used where corrosive conditions dictate. Most commonly used is 304, .010 .016 can be used when a more damage resistant finish is desired. Where extreme corrosive conditions are encountered, 316 stainless steel should be used.

An additional product for outdoor use is FlexClad 400 for weather sealing ducts and pipes, available in aluminum, white and gray; it is a laminate of aluminum, high strength polymer film and rubberized asphalt adhesive. The adhesive system is designed to adhere to faced insulation.

What is the difference between iron pipe size (IPC) and Copper pipe size for pipe insulation?

There are four sizes of copper where the iron pipe size is so close to copper that fiberglass insulation manufacturers make one size to fit both. (see table below). This is not true with manufacturers of elastomeric insulation (like Aerocell EPDM rubber insulation) who make copper sizes for those four sizes.

1/2 in. copper = 5/8 in. copper = Buy 5/8 in. copper (.625 diameter)
3/4 in. copper = 7/8 in. copper = Buy 1/2 in. Iron Pipe Size (0.84 diameter)
1 in. copper= 1 1/8 in. copper = Buy 3/4 in. Iron Pipe Size (1.05 diameter)
1 1/4 in. copper = 1 3/8 in. copper = Buy 1 in. Iron Pipe Size (1.315 diameter)
1 1/2 in. copper = 1 5/8 in. copper = Buy 1 1/4 in. Iron Pipe Size (1.660 diameter)

The following are the same:
2 1/8 in. copper = Buy 2 1/8 in. copper
2 5/8 in. copper = Buy 2 5/8 in. copper
3 1/8 in. copper = Buy 3 1/8 in. copper
4 1/8 in. copper = Buy 4 1/8 in. copper
5 1/8 in. copper = Buy 5 1/8 in. copper
6 1/8 in. copper = Buy 6 1/8 in. copper
and so on..
