There are applications within petrochemical, metals and minerals, power generation or pulp and paper plants that can be quite demanding on the valves and piping installed at the facility, and these requirements can vary greatly from a one process to another.

Big Taps Valve Consultants understand how Corrosive acids, extreme operating conditions, high temperature reactors, critical safety applications, high-pressure conditions, and abrasive service make high demands and affect the performance and life span of your valves.

Typically, every plant has a few severe services hotspots, these piping and valve hotspots can be extensive and essential pieces of equipment that need to be protected, reliable Taps Valve Consultants can specify the correct industrial valves, alloys and design all specifically devised to meet the challenges of your particular application.

The use of high-alloy valves is therefore significant within the demanding processes. Exotic alloy valves provide processes with safety, durability, efficiency and functionality. Super duplex valves, for example, are highly suited for marine, subsea and desalination applications. Monel valves, on the other hand are mostly found in alkylation processes where HF acid is involved, and oxygen services. Acids and slurries might also require special material valves to withstand wear and tear.

The proper performance of a valve will not only ensure the process’s integrity and plant personnel’s safety, but also the rate at which the plant can manufacture products. In most processing plants, there are multi-stage or single letdown systems between the raw-material processing, upstream end of the process, and the downstream, final end product. These systems may include reducing the pressure in the flow while at the same time ensuring the media’s integrity. By decreasing pressure, energy can be released in many stages in order to stabilize the media’s flow before it arrives downstream to deliver the required process or product conditions. Special valves installed along different points at the facility can offer the desired control characteristics.

Severe service valves are installed both at the injection (beginning) and the withdrawal (end) of the process. The ones located in the end of the process’s reaction are often exposed to harsh conditions, which could be punishing to the usual commodity valve, hence the use of alloy material. The usual conditions that extreme valves should handle on the reactors may include abrasive media, high pressure or high temperature, acids, slurries.

Chemical & Petrochemical

Our valves meet the standards required by a wide range of petrochemical applications, such as ethyulene cracking, steam cracking, FCC, EDC, liquid sulphur, VCM, cracked gas, PVC, polymerisation, dichlorehane, product discharges from reactors and CCR.

Acids & Slurries

A slurry is a thin sloppy mud or cement or, in extended use, any fluid mixture of a pulverized solid with a liquid (usually water), often used as a convenient way of handling solids in bulk. Slurries behave in some ways like thick fluids, flowing under gravity and being capable of being pumped if not too thick. The abrasive or corrosive nature of some slurries warrant the use of exotic alloy valves.

Corrosive Gases

Oxygen, nitrogen, argon, LNG, chlorine or similar challenges?

HF acid and alkylations service at UOP plants

Looking for K500 monel valves suitable for HF acids and alkylation for hydrofluoric acid service we can help. Valves for HF acid and alkylation in A494 MR-35-1, both according to UOP as well as ConocoPhillips (formerly Phillips) specifications, as well as the demanding NACE 5A-171 specification covering "Materials for Storing and Handling Commercial Grades of Aqueous Hyrofluoric Acid and Anhydrous Hydrogen Fluoride".

Cryogenic & Low Temperature Service

Cryogenic valves are designed valves for use at temperatures down to -196C. Cryogenic valves are constructed from austenite stainless steel for high corrosion resistance in marine environments. They are ideal for LNG service, as well as nitrogen and LPG applications. The cryogenic nature of some applications warrant the use of exotic alloy valves. The valves come with an extended stem and bonnet, and are generally metal seated.
