21/4/2020· Sulfuric acid is one of the most widely used chemicals across a range of industries. Despite this ubiquity, however, each sulfuric acid appliion requires careful material selection and evaluation, as the wrong gasket will quickly deteriorate, posing a multitude of risks when exposed to this aggressively corrosive medium. It is absolutely critical that sulfuric acid […]

Flexible hoses are not generally used in a sulphuric acid plant except where absolutely necessary because they represent a weak point in the piping system and there is a higher potential for leaks and accidents involving hoses. One loion that flexible hoses are used is in the offloading of railcars or tank trucks.

Sulfuric Acid Loading Arms. OPW has provided many solutions to frustrated producers who have struggled with their Sulfuric Acid (H2SO4) loading operations for years. If dealing with Sulfuric Acid in concentrations of 93% and above, an OPW Loading Arm is an excellent way to improve the Safety & Efficiency of your loading operations.
A Teflon® PTFE-lined hose is acceptable for 93-98% sulfuric acid service. The hose should be designed with a 200-psi minimum working pressure and be full vacuum rated. The end fittings must be crimped or swaged - banding is not recommended. The hose manufacturer must list the hose as "satisfactory" for 93-98% sulfuric acid service.
12/9/2011· Re: Material of construction for pumping sulphuric acid at 98% concentration. Too small flow for a centrif. This is metering pump territory. You could use a hose pump a la dvmdsc, or diaphragm type metering pump (PTFE or similar diaphragm). Maybe a small helical rotor pump if available in resistant materials.

changing to a higher concentration acid. In concentration of 98.3 percent or higher, sulfuric acid has a natural contaminant, known as sulfur trioxide (SO. 3). The SO. 3. associated with concentrated sulfuric acid has very affinity for water, and can actually chemically dehydrate polyester or vinyl estertoyieldacharred surface. SO. 3
