Must stainless steel bolts be used for stainless steel flange?   There are often many owners who force the contractor to rectify the stainless steel flange by selecting carbon steel or alloy steel bolt, but the Contractor’s numerous grievances are hard to explain. But is it really hard to explain?   Actually, it’s a good

Blind Flanges What is a Blind Flanges. A Blind flange is round plate which has all of the relevant boltholes but no center hole, and because of this feature this flange is used to close off the ends of a piping systems and pressure vessel openings. It also permits easy access to the interior of a line or

What is a Weld NeckFlanges. A Weld Neck Flanges (also known as a high-hub flange and tapered hub flange) is a type of flange. There are two designs. The regular type is used with pipes. The long type is unsuitable for pipes and is used in process plant. A Weld Neck Flanges  consists of a circular fitting with

Slip On Flange 1.What is a Slip-on Flange. Slip on Flange, also called SO flange. It’s a kind of flange slides over the pipe with internal design is slightly larger than the pipe. Since the inner diameter of the flange is slightly larger than the outer diameter of the pipe, the SO flange can be directly

Flange is also called flange plate. Flange is the part connecting the pipe to the pipe, which is connected to the pipe end; it is also useful for the flange on the equipment inlet and outlet, which is used for the connection between two equipment, such as the reducer flange. Flange connection or flange joint

Forged flange is one of the products with the best mechanical properties in flange products. Its raw material is generally tube blank, and then it is cut and hammered continuously to eliminate segregation, looseness and other defects in ingot. The price and mechanical properties are one grade higher than that of common cast flange. Flange

The shape and size of the casting blank are accurate, the machining amount is small and the cost is low, but there are casting defects (porosity, crack and inclusion); the internal structure streamline of the casting is poor (if it is a cutting part, the streamline is worse); The advantages of the casting are that

FIGURE 8 BLIND FLANGE is a solid plate or common steel plate used to block the pipeline equipment at the connection of two flanges. The purpose is to test the pressure, leak and block the pipeline of pipeline equipment. The product pipe size range is & frac12; “to 96”, and the flange grade range is

Production reached a record high. From January to June 2013, China’s total production of crude steel was 390 million tons, up 7.4% year on year, 5.6 percentage points higher than that of the same period last year. In the first six months, the average daily output of crude steel was 2.154 million tons, equivalent to

There are some points of SEAMLESS PIPE welding: 1. Adopt the power supply with vertical external characteristics, and adopt the positive polarity (welding wire is connected to the negative electrode) when DC. 2. It is generally suitable for the welding of thin plates under 6mm, with the characteristics of beautiful weld forming and small welding deformation.
