Frequently asked questions
What is inhibited hydrochloric acid and where is it used?
Inhibited hydrochloric acid (CAS 7647-01-0) is an aqueous HCl solution with an added corrosion inhibitor; depending on grade it contains 22-32% HCl by mass. It is used for acid stimulation (matrix acidising) of oil and natural gas wells; chemical cleaning of inorganic deposits from boilers, heat exchangers and industrial equipment; acid pickling of ferrous and non-ferrous metals; carbonate dissolution; and surface preparation before galvanising.
What packaging is available and is it kept in stock?
It is supplied in bulk in airtight tanks made of materials resistant to hydrochloric acid (rubber-lined or enamelled steel) (UN 1789). It must be stored at 5-30°C in well-ventilated, closed warehouses protected from sunlight and precipitation. KORKİMYA ships ex-stock and keeps local stock against import lead times.
Is it REACH-registered and is a safety data sheet provided?
Yes. The product is registered under the Turkish KKDİK / REACH framework and ships with a compliant safety data sheet (SDS). As the acid is corrosive, the SDS instructions to store and transport it separately from alkaline and organic substances must be followed.
How can I get a sample and a price quote?
KORKİMYA offers samples and price quotes with invoicing. Grade values such as HCl content, corrosion rate and iron content, plus a certificate of analysis (CoA), are shared on request. Specify the grade you need (A, B/C, D), quantity and delivery location to receive a quote.
