There are a number of casing pipes suppliers who manufacture seamless pipes and casing pipes with various grades of steel and its alloys. They offer pipes with description such as API 5I Gr B Pipes, API 5I Gr x 65 pipes, API 5I Gr X 52Pipes, etc. These names indicate different grades of pipes which have been tested using specific testing methods as per the area of application. They are designed to suit specific requirements in variety of industries such as petroleum, oil and gas, fluid and gas transfer, etc.
These pipes made of carbon steel or stainless steel is available in various shapes, sizes and grades to meet the variation in demand of the industries. The steel casing pipes also known as the encasement pipes are commonly used in the underground network of utility lines in oil rigs, petrochemical plants, etc. It is important to go to the reputed casing pipes suppliers to guarantee product and people safety.
These encasement pipes are welded into ribbon and then pulled through a pre bored hole under the highways, rail lines, water, etc. Another way is to jack the pipes into a hole in segments and then connect using welding or threaded ends. Their ends are sealed with the pull on or wrap around seals. Utility lines such as water, gas, electricity, power cables etc. are mounted within the steel casing pipes using spacers. Socket weld fittings and screwed threaded fittings are commonly used. Since these utility lines are usually underground it is essential to use the expertise of known casing pipes suppliers. They will ensure safe onsite installation, check their operation as per stringent quality standards and verify on the job performance by continuous monitoring before handing it over to the client. Such renowned suppliers also provide the necessary training and documentation to meet the safety norms of the industry.
The various grades of casing pipes API 5I Gr B Pipes, API 5I Gr x 65 pipes , API 5I Gr X 52Pipes, etc. are fabricated in various shapes like square, rectangular or round and are made from carbon steel or other steel alloys. This depends on the customer requirement and the end use. These numbers confirm a strict control on testing that is undertaken before installation in a particular industry. Their yield and tensile strength tolerances are as per the intended use. This is to ensure increased life span of the utility lines by making them resistant to corrosion due to harsh environmental conditions. For example, in an oil and gas industry the utility lines which experience tremendous external pressure, high collapse material is used to increase the endurance. Factors like temperature, deep well service and thermal service are considered to protect the utility lines from damage.
Our daily lives are totally dependent on the effective functioning of utility lines. Encasement pipes play a vital role in this regard as they form a protective cover around the utility lines which run under our roads and also safeguard everything above them.
