Malleable Iron Npsl Threaded Lock Nut

Description

This threaded lock nut, made of malleable iron, is commonly used in low pressure flow applications and is ideal for linking air, water, fuel, oil, and inert gas lines. The cast iron fitting undergoes forging, heat treatment, and coating treatment to ensure good corrosion resistance, making it suitable for high temperature and high pressure environments. It follows standard U.S. pipe threads, also known as NPSL, and threads directly onto the male end of the fitting for added security against loosening due to vibration. Its simple and compact structure is available in a range of sizes, making it adaptable to various pipelines and easy to install by hand or tools.

Features

2. Accurate dimensions: Utilizing cast iron material with excellent ductile properties and ease of formability, this Npsl Threaded Lock Nut demonstrates precision in its structural design. Automated processing equipment further ensures that all products conform to required specifications, providing impeccable accuracy in dimension and quality.

The versatility of this pipe fitting is evident in its availability in three different structures - heavy, medium, and light. But despite their varying weight and size, all structures possess remarkable strength and a minimum tensile strength of ≥300MPA. This means that the fitting can withstand heavy loads without cracking or deforming under pressure. The high strength of this pipe fitting ensures longevity and reliability, making it an ideal choice for commercial, industrial, and residential applications.

Corrosion resistance is a key feature of this product, and it offers three effective surface treatment methods: galvanizing, electro-galvanizing, and black oxidation. By utilizing galvanizing and electro-galvanizing, a protective zinc layer is applied to the surface, safeguarding the cast iron substrate against corrosion. Alternatively, with black oxidation, a reaction occurs with oxygen, forming a resilient black oxide layer. This layer not only shields the metal from corrosion but also improves the surface hardness of the product. Hence, customers have multiple options to ensure the longevity and durability of the cast iron substrate.
