HYDROSTATIC AND NON-DESTRUCTIVE ELECTRIC TESTING

Hydrostatic inspection test pressures for plain-end pipe are listed in follow table of the A53 / A53M industry specification. Test pressures are maintained for a minimum of five seconds. Non-destructive electric testing of the weld seam is required on each length of ERW pipe NPS 2 and larger.

erw 生产工艺流程

Products description

ERW (Electric Resistance Welded) pipes are welded longitudinally, manufactured from Strip / Coil and can be manufactured up to 24” OD. ERW pipe cold formed from a ribbon of steel pulled through a series of rollers and formed into a tube which is fused through an electric charge.

 ERW are used for mechanical and pressure applications, and for ordinary uses in steam, water, gas and air lines. More than 350 different combinations of finish, end treatments and lengths are available on standard pipe. Our standard process is hot-dip galvanization to ASTM A53 requirements.
