An Injection Assembly typically for use with High Pressure Access Systems consists of an Access Fitting body with a side Tee through which the fluid transfer takes place. The Tee may be threaded or welded. Welded Tees are either flanged or buttweld nipples. Threaded Tees depend on an NPT tapped hole on the fitting body. The Tee size is rated depending on the injection rate and the injected chemical's viscosity.

Crystal Industrial's Flareweld Access Fittings are the most popular type of corrosion fitting mounting configuration. We are one of the most proven manufacturers and exporters of the product. The model AFI Flarweld access fitting body is designed to be welded directly onto the pipe or the vessel. The corrosion access fitting has a radius that matches the curvature of the pipe or the vessel, with a maximum weld gap of 1/16”

Clad plates are utilised as raw material for the manufacture of metallurgically cladded pipes. The plates comprise a base material and a corrosion resistant alloy material. They are bonded together firmly by a diffusion bridge. Crystal Industrial's Cladded Pipes & Fittings are employed in industries of water, oil and gas refineries besides in sub-sea applications. In our cladded pipes the weld metal is layered on the surface of the work, as against merely joining two pieces of material. This is usually done for achieving wear and corrosion resistance. We use a range of materials including carbon steel, stainless steel and low alloy steel.  

Cladded plate is a composite steel plate produced by bonding any cladding material (like stainless steel) plate to one side or both sides of a carbon steel or low. Hence a clad steel plate not only has adequate strength expected of structural materials (base metal) but also has other features like resistance to heat and corrosion (cladding material) and is more cost-effective then using similar products made entirely of the cladding material. Crystal Industrial's cladded plates are used in a range of industries including construction, ship building and manufacturing of heavy-duty tanks.

Circular coupons are most usually used along with holders that mount the coupon flush with the interior of the pipe or vessel. They come with a chamfered hole which allows recessed mounting accompanied by a stainless steel flathead screw. Flush disc coupons are usually used where pigging otherwise requires the taking out of intrusive-type coupon assemblies before the pigging operation; or alternatively where water-drop out at the bottom of the horizontal pipe runs causes corrosion problems. The disc coupon diameter is 1¼" (32 mm) with a thickness of 1/8" (3 mm). The insulation and the mounting screw is provided along with the coupon holder.

Corrosion coupons are strip shaped or cylindrical pieces of metal that can be installed in nearly any accessible location in the system. They are mounted on the appropriate coupon holder and usually placed directly in the flow line and used to calculate a corrosion rate.
