ISO 11960 Certifications
ISO 11960 Accreditation provide SO 11960 Certification . ISO 11960 offers with Petroleum and natural gas industries — Steel pipes for use as casing or tubing for wells.
ISO 11960:2010 decides the specialized conveyance circumstances for metallic channels (packaging, tubing and household dog joints), coupling stock, coupling material and adornment material and builds up necessities for 3 item determination levels (PSL-1, PSL-2, PSL-3).The requirements for PSL-1 are the idea of ISO 11960:2010. The requirements that characterize various stages of preferred specialized prerequisites for PSL-2 and PSL-3, for all evaluations apart from H-40, L-eighty 9Cr and C110.
For pipes covered by way of ISO 11960, the sizes, loads and wall thicknesses in addition to grades and relevant give up-finishes are listed. By agreement among the client and producer, ISO 11960 can also be carried out to different plain-cease pipe sizes and wall thicknesses.
ISO 11960 is relevant to the following connections according with API Spec 5B:
For such connections, ISO 11960 identify the technical delivery situations for couplings and thread protection. Supplementary requirements that may optionally be agreed for improved leak resistance connections (LC) are given.
ISO 11960 can also be applied to tubulars with connections no longer blanketed by ISO/API standards.
The four agencies of merchandise to which ISO 11960:2010 is relevant encompass the subsequent grades of pipe:
Group 1: Involving all casing and tubing in grades H, J, K, N and R
Group 2: Involving all casing and tubing in grades C, L, M and T
Group 3: Involving all casing and tubing in grade P
Group 4: Involving all casing in grade Q
Supplementary necessities which can optionally be agreed between consumer and manufacturer for non-detrimental examination, completely machined coupling blanks, upset casing, electric-welded casing, tubing and doggy joints, impact testing, seal ring couplings, take a look at certificates, tensile checking out and sulfide stress cracking testing are given.
