Pipe flanges

SunnySteel is a merchant exporter and supplier of pipe flanges. Pipe flanges are disc, collar or ring that attaches to pipe with the purpose of providing increased support for strength, blocking off a pipeline or implementing the attachment of more items.  Pipe flanges are usually welded or screwed to the pipe end and are connected with bolts.

Pipe flanges

Pipe flangea are method of connecting pipes, valves, pumps and other equipment to form a piping system.

The most used flange types in Petro and chemical industry are:

Blind-flangesBlind flanges

Blind pipe flanges are pipe flanges used to seal the end of a piping system or pressure vessel openings to prevent flow. Blind pipe flanges are commonly used for pressure testing the flow of liquid or gas through a pipe or vessel.

Lap Joint Flanges (LJ Flanges) are used on piping fitted with lapped pipe or with lap joint stub ends the combined initial cost of the two items being approximately one-third higher than that of comparable welding neck flanges.Lap Joint Flanges (LJ Flanges)

Orifice Flanges generally come with either Raised Faces or RTJ (Ring Type Joint) facings.Orifice Flanges

Orifice Flanges are used with orifice meters for the purpose of measuring the flow rate of either liquids or gases in the respective pipeline.

A reducing flange consists of a flange with one specified diameter having a bore of a different and smaller, diameter.Reducing Flanges

RTJ Flanges, Ring Type Joint FlangeRTJ Flanges, Ring Type Joint Flange

Ring Type Joint Flange is a method of ensuring leak proof flange connection at high pressures. A metal ring is compressed into a hexagonal groove on the face of the flange to make the seal. This jointing method can be employed on Weld Neck, Slip-on and Blind Flange.

Socket welding flangesSocket welding flanges

Socket welding flanges are counter bored to accept the pipe before being fillet welded. The bore of the pipe and flange are both the same therefore giving good flow characteristics.

Slip-On flanges or SO flanges are commonly lower in price than weld-neck flanges, and to this effect are a popular choice for our customers. Slip-On flanges, SO flanges

Slip-On flanges or SO flanges are commonly lower in price than weld-neck flanges, and to this effect are a popular choice for our customers.

Threaded flanges look very similar to Slip-On flanges but the main difference is that the threaded flange has been was bored out to match a specific pipe inside diameter. The backside of this center opening is then threaded with the relevant-sized tapered pipe thread.Threaded flanges

Weld-Neck flanges or welding-neck flanges can be differentiated from all other types of flange by their long tapered hub. In addition, there is also a gentle transition of thickness in the region of the butt weld that joins them to pipe or a fitting. Weld-Neck flanges

We have the professional engineers, measurement the size of Pipe flanges.

Measure the size of a flange

At some point, with all the possibilities of thread form, diameter, and pitch, you need to send it off to SK Grimes or another machinist.

Gaskets for Flange ConnectionsGaskets for Flange Connections

Flange gaskets are used to create a static seal between two flanges faces, at various operating conditions, with varied pressure and temperature ratings.

Forged FlangeForged Flange, Forged steel flanges

Forged flange is defined as a plate type device, normally round, that is attached to the end of a pipe, fitting, valve or other object to facilitate the assembly and disassembly of a piping system.

Advantages of Expander FlangesWhat is an Expander Flange?

Expander Flange is a Welding Neck pipe flange where the nominal size of the non-flanged end is larger than the nominal size of the flanged end. They can be used to change the size of a pipe run.

China Hit With Heavy Cold-Rolled Steel Duties, Korean and Russian Imports Mostly Unharmed

Today, the Commerce Department announced its affirmative preliminary determinations in the countervailing duty investigations of imports of cold-rolled steel flat products from Brazil, , India, and Russia, and its negative preliminary determination in the CVD investigation of imports of cold-rolled steel flat products from South Korea.

The investigations cover cold-rolled, flat-rolled . It should come as no surprise that the largest subsidies are being assigned to Chinese importers.

Chinese Imports Take a Hit

In the China investigation, Commerce preliminarily determined that mandatory respondents Angang Group Hong Kong Co., Ltd. and Benxi Iron and Steel (Group) Special Steel Co., Ltd. and, a non-cooperative exporter — Commerce’s term for companies that do not respond to requests for information in the investigation — Qian’an Golden Point Trading Co., Ltd., received whopping subsidy rates of 227.29%.

All other exporters of cold-rolled steel flat products from China will be subject to that same subsidy rate of 227.29%. The rates are based on adverse facts available. Commerce determined that the Government of the People’s Republic of China, and the mandatory respondents, did not fully cooperate in the investigation.
