Questions
Frequently asked questions
What is the difference between E6013 and E7018 electrodes?
E6013 is a rutile general-purpose electrode: easy to strike and run, good appearance, suited to thin material and non-critical work. E7018 is a low-hydrogen basic electrode with higher tensile strength and toughness, required for structural, pressure and code work where cracking resistance matters. E7018 must be kept dry — vacuum-packed or oven-stored — and the -1 suffix denotes improved low-temperature impact properties.
What does EN 853 2SN mean on hydraulic hose?
EN 853 is the European standard for wire-braid hydraulic hose. 1SN has one steel wire braid, 2SN has two, giving higher working pressure for the same bore. The equivalent SAE designations are 100R1AT and 100R2AT. Working pressure falls as bore increases; the standard tables give the rating for each size. EN 856 4SP and 4SH are spiral-wire hoses for higher pressures.
What certificate should come with lifting gear?
Every item of lifting equipment must be supplied with a manufacturer’s certificate of test and conformity stating the working load limit, the standard, the proof load applied and a unique identification number matching the marking on the item. Before first use, and periodically thereafter, a thorough examination by a competent person is required under most national regulations. CRS PLUS supplies the manufacturer’s certificate with every lifting item.
What is the difference between grade 8.8 and 10.9 bolts?
The property class in ISO 898-1 gives the tensile strength and yield: 8.8 has a minimum tensile strength of 800 MPa and yield of 80 % of that, 640 MPa; 10.9 has 1000 MPa and 900 MPa. Grade 10.9 is used where higher clamping force is required and for high-strength structural connections; 8.8 is the general-purpose structural grade. Both must be marked on the head.
Which steel grade for structural work in the Gulf and Africa?
S275 and S355 to EN 10025 are the standard structural grades in projects following European codes; A36 and A572 grade 50 in projects following American codes. S355 and A572 grade 50 are broadly equivalent. Plate for pressure equipment is normally A516 grade 70. The project structural specification states the grade, and the mill certificate must show it.
What is needed to quote consumables?
A bill of quantities stating, for each line, the classification or grade, size, quantity and packaging, the finish where relevant, and the certification required. For hose assemblies, the bore, pressure, length and end fittings. For lifting gear, the working load limit and the standard. Repeat-order schedules can be held for regular call-off.
Where are the materials sourced from?
CRS PLUS sources consumables and materials from its qualified supplier base of certified manufacturers and mills in China, India, Europe and the Gulf. Origin and certification are stated on each quotation. CRS PLUS does not name manufacturers on this page and holds no distribution or agency agreement with any of them.
