Categories of Steel Pipe
According to methods of steel manufacturing, steel pipe is divided into two types: welding steel pipe and seamless steel pipe. Seamless steel pipe is made from high-quality carbon steel or alloy steel, which includes hot-rolled, cold-rolled pipe. Welded steel pipe is formed by rolled steel with the shape of a tube, which is welded together in the seam or spiral seam. As per manufacturing methods, it can be divided into welding steel pipe for transportation of low-pressure fluid, seam welding spiral steel pipe, welded steel pipe etc. Seamless steel pipes can be used for a variety of liquids, and gas pipelines, while welded pipe can be used for water pipes, gas pipes, heating pipes and so on.

Steel Casing Pipe
Steel Casing Pipe, also known as encasement pipe, is most commonly used in underground construction to protect utility lines of various types from getting damaged. Such damage might occur due to the elements of nature or human activity.
Steel casing pipe is used in different types of horizontal underground boring, where the pipe is jacked into an augered hole in segments and then connected together by welding or by threaded and coupled ends, or other proprietary pipe connectors. The steel casing pipe can also be set up and welded into a “ribbon” and then directionally pulled through a previously drilled hole under highways, railroads, lakes and rivers.
Uses
Steel casing pipe protects one or many of various types of utilities such as water mains, gas pipes, electrical power cables, fiber optic cables, etc. The utility lines that are run through the steel casing pipe are most commonly mounted and spaced within the steel casing pipe by using “casing spacers” that are made of various materials, including stainless steel or carbon steel and the more economical plastic versions. The ends of a steel casing pipe “run” are normally sealed with “casing end seals”, which can be of the “pull-on” or “wrap-around” rubber varieties. Steel casing pipe is also used in the construction of deep foundations.
Specification
Steel casing pipe generally has no specific specifications, other than the need for the material to be extremely straight and round. In some areas A.S.T.M. specifications may be required by project engineers. The specification most commonly called for is A.S.T.M. 139 Grade B. This specification gives parameters for minimum yield and tensile strength of the steel pipe being used for casing, and tolerances of straightness and concentricity.
Steel casing pipe is often specified as ASTM A-252 which is a structural grade material that does not require hydrostatic testing and the inspection requirements are not stringent and it usually costs less than other grades such as A-53, A-139 or API 5L. Used natural gas line pipe is also used as casing on many projects because it is often reclaimed in very good condition and can offer a significant cost savings when compared to new steel pipe. Used pipe is most likely to not have any testing data associated with it and is generally used when the only required specification is a given diameter and wall thickness of steel casing pipe.

Corrugated stainless steel tubing
Corrugated Stainless Steel Tubing (CSST) is a type of conduit used for natural gas heating in homes. It was introduced in the United States in 1988. CSST consists of a continuous, flexible stainless-steel pipe with an exterior PVC covering. The piping is produced in coils that are air-tested for leaks.
In the United States, about 500,000 new homes per year have CSST installed; that number is about half of the number of new homes that have natural gas for heating or cooking. As of 2007, about 2 million homes in the United States had CSST installed.
CSST is installed much like electrical wiring, and thus more quickly than traditional black-steel pipe, but the cost of the material is several times more than black-steel pipe.
In mid-2007, four CSST makers settled a class-action lawsuit. The settlement provides money to fix problem pipes The settlement provided money to fix problem pipes by bonding the CSST to the electrical systems with thicker wire.
