Why does the tee need to do the blasting before painting?

Blasting before painting is an essential step in the process of preparing a tee for coating. The main reason for blasting is to remove any impurities, contaminants, rust, or old paint from the surface of the tee. These impurities can prevent the paint from properly adhering to the tee, leading to premature paint failure and corrosion.

Advantages and Disadvantages of Socket Weld fittings

Socket weld fittings are commonly used in piping systems for their ease of installation and ability to withstand high pressure and temperature. One of the main advantages of socket weld fittings is their ability to provide a strong and leak-proof connection.

General application of pipe flanges

A pipe flange is a method of connecting pipes, valves, pumps and other equipment to form a piping system. It also provides easy access for cleaning, inspection or modification. Flanges are usually welded or screwed.

Advantages and Disadvantages of Socket Weld fittings

Radiography is not practical on the fillet weld; therefore correct fitting and welding is crucial. The fillet weld may be inspected by surface examination, magnetic particle (MP)

Why does the tee need to do the blasting before painting?

Before painting, pipe tees must do the blasting. The blasting process adopt compressed air to form a high speed jet beam, spraying the material on the surface of the tees

Steel pipe bends material and caculating

Pipe fittings are necessary to join together pipes, or to change the direction of an existing pipe. Pipes and pipe fittings are made of a variety of materials, depending on the fluid or gas being transported.

Do you know what are the sides of the flange？

The Raised Face flange is the most common type used in process plant applications, and is easily to identify. It is referred to as a raised face because the gasket surfaces are raised above the bolting circle face.

The differences between ASME B16.5 and ASME B16.47 Series A, Series B

ASME B16.5 standard covers Steel Pipe Flanges and Flanged Fittings from NPS 1/2 through NPS 24 Metric/Inch in pressure class 150 to class 2500

Advantages of flat welding flange and its precautions

The flat welded flange not only saves space, reduces weight, but more importantly ensures that the joint is not leaked and has good sealing performance.

What's the difference between the butt weld fittings and socket fittings?

Butt welding connection is to fix all the two parts after spot welding, of course, the welder's requirements are also slightly higher

Which flanges are we often used？

The Socket weld flanges are attached by only one fillet weld, only on outside, and are not recommended for severe services. These are used for small-bore lines only.

Product information about elbows

Steel pipe elbow (sometimes also refereed as bends) is a key part in a pressure piping system used to change the fluid flow direction. It is used to connect two pipes with same or different nominal diameters

What are the materials of flanges

Carbon steel flange. This is the most common flange material, mainly composed of carbon and iron, the price is relatively low, suitable for a variety of environments and occasions, such as municipal engineering, shipbuilding, chemical, oil, natural gas and so on. Carbon steel flanges have high strength and poor corrosion resistance, and need to be regularly maintained and replaced.
