PIPE SPACER

Our range of pipe casing spacers / insulators centre water and sewer pipes in casings. They are used to support and electrically insulate a pipeline from a casing pipe through which it must pass. The spacers are easy to install, are virtually corrosion proof, and provide insulating protection from a possible electrical shorting between the carrier pipe and casing. No special tools are required and they are easily applied by a single worker. The casing spacers eliminate the need to fill the casing annulus with sand and as they are so easy to remove, it allows damaged pipes to be repaired or replaced quickly. Let us know what your required runner height is (annular clearance between the inner pipe and the outer casing) and we will offer you a suitable solution for your pipeline.

HYDROFLUORIC ACID ALKYLATION SERVICES UNIT

HF-N Piping Products are Suitable for are suitable for use with hydrofuoric acid (HF) as a catalyst in converting isobutane and low-mole-cular-weight alkenes into alkylates. The process occurs in the presence of a strong acting acid such as sulfuric acid or hydrofluoric acid (HF) as catalyst. Depending on the acid used, the unit takes the name of SAAU (Sulphuric Acid Alkylation Unit) or HFAU (Hydrofluoric Acid Alkylation Unit). Depending on the acid used, the unit takes the name of SAAU (Sulphuric Acid Alkylation Unit) or HFAU (Hydrofluoric Acid Alkylation Unit).
